Wireless charging cant get much better than that
I've heard banter about wireless charging over time, never really looked into it,
Being part of the device such as DNA will they be selling what accessory to allow this? a Mat or ?

Case with wireless charging
Can we have a case on the device when we're wirelessly charging or do we have to repetitively take the case on and off when we charge? That would be a big let down if we had to. Thanks in advance.

once i find a case that will fit i will give it a try, since the wireless pad is on my to purchase list tomorrow
Sadly, what I've been reading is that it depends on the case. Wireless charging seems to be out for the outer box users out there.
How about disruption?
If I for example, took my DNA, Keys, change etc out of my pocket and just plopped it all down on the charge pad, would the keys/change effect it's ability to charge?
Is it induction? Using Magnetic Fields etc...
Is it using the same wireless charging standard as the Nexus 4?
Correct me if I am wrong, but the DNA (at least) is using the Qi standard (http://en.wikipedia.org/wiki/Qi_(inductive_power_standard)), same as Nokia's new line up. But IDK about the Nex4.
Edit: seems like they both use Qi after all. Standards are great when they actually are used, haha. But hopefully this means the price of chargers will decrease. My only hope is that there are magnets on the back of the DNA to hold it in place, like on the Nex4.
I'm quite sure that the "wireless charging" technology is not wireless power. It's just a way of charging where it passes through the back of the case and it's at such a low voltage that you don't have to worry about touching the mat yourself. It's called wireless because it doesn't use an actual wire/cord, but calling it "cordless charging" would have been more accurate.
So I'd assume that most cases would block it, unless they are thin enough for the electricity to easily pass through. Even if it does charge, the case might slow it down.

actually the surface of the charger is not electrified at all. Its etromagentic which means the charge or field origninates from within the device and therefor there is absolutely zero danger due to physical contact and the case only has an effect based on the distance it moves the inductive coils in the phone from the base station. It cannot slow the charge unless it somehow has a faraday effect blocking out the electromagnetic field. http://en.wikipedia.org/wiki/Wireless_charging

excuse spelling errors
It's like an induction hob for a kitchen cooker.
There will be a magnetic coil in the pad that, once the phone is placed onto it, will complete an electro-magnetic circuit and power the phone. iirc...
But I remember reading about how it's very different technology than "wireless power" and that you couldn't use this to power something like a PS3 because it would be dangerous and shock other things, where as something like MIT has done could power a room full of devices and you wouldnt have to worry about things getting a charge that weren't meant to. Could be wrong though, or might have been on older "wireless charging" units.
First there are many forms of wireless charging (ie. wireless transmission of electricity). In the context of the DNA (and other phones: Lumia's, Nexus 4, etc.), the method used is "Inductive Charging" (the Qi standard linked in my previous post). In this situation, the only damage that can be caused is via magnetic interference; for example, the consortium supporting Qi, posted some guidelines that hint at potential interference (AM radios, key fobs, etc.), but I don't think that this is a severe problem. Keep in mind that inductive charging has been around for years; it has just only recently become efficient enough to use (practically) in mobile devices.

The ps3 wouldnt pull a charge from it period. It must have an inductive charging coil inside of it to conver the AC electromagentic field to something useful otherwise the charging pad would have little effect on it other then subjecting it to an EM field. There is no actual physical connection established between the device and whatever its charging outside of the EM link thus "wireless" charging.

Well, I meant something as powerful with an adapter to receive the power, not putting some coils next to it and hope for some magic to happen if you give them enough power. lol

Currently the Qi standard has provisions for both "low" and "medium" power devices. Low caps out at 5W (I believe), suitable for mobile phones, etc. But the Medium power spec does hold the potential for larger more energy consuming devices.
Keep in mind, however, that the transmission process is lossy, and you only get 60-90% efficiency (okay for small devices, harder to justify for a PS3 ).
I have a wireless "Inductive" type charging mat for my Wii controllers and it works with the rubber cases still on them

Hi Folks
After digging through mounds of tech docs, I was able to verify that the G-Tab uses the TI TPS658621A power management processor for charging.
Good news - you can plug just about anything into it from 9V up to 18V and it should charge it. Theoretically, it should also support step up charging from USB (trickle charge) but I've yet to prove that. (The power management processor supports it, but it might not be in the hardware.)
Bad news - it's just out of reach for a standard laptop charger (19V) so we still need a converter.
So, if you find a connector that fits it, plug it in. Don't worry about the current draw - as long as it's 1A or GREATER it should work fine (the device won't pull more than an 1A, even though our chargers are spec'd for 2)
Technical specs are available here - http://focus.ti.com/docs/prod/folders/print/tps658621d.html
This is awesome info! That means for the car all we need is a fused line to the right plug (center positive of course.)
This is great news, this means that the iGO tip that sends out 19v is safe to be used on the GTab.
Thanks for sharing.

While you might be able to do that, I don't recommend it. If you do it anyway, do yourself a favor and NEVER EVER EVER leave it plugged in while you are starting the car.
From Wikipedia:
A second problem is that nominally "Twelve-Volt" power in cars fluctuates widely. The actual voltage will be approximately 12.5 volts when dormant, (less when cold) approximately 14.5 volts when the engine and the alternator/generator are operating, (more when cold) and may briefly drop as low as 5-6 volts during engine start.[7] DC/DC converters will usually compensate for these small fluctuations.[citation needed]
Rarely, more extreme cases of voltage fluctuation can occur when the car battery is disconnected while the engine is running, or when the car receives a jump start. When the battery is disconnected, a load dump transient can produce very high voltages. A car receiving a jump start from a truck will be subject to its 24 V electrical system.[8] A "double battery jump-start" is performed by some tow truck drivers in cold climates.[9]
Design wise one has to take into account intermittent contact, and voltages outside the nominal 12 V DC like top voltage 9-16 V continuously, top voltage at 20 V during 1 hour, 24 V during 1 minute, 40 V during 400 ms.[10] Protection component tolerance example ratings are +50 to -60 V DC[11] Besides this there's also varying temperatures between -40 till +85 °C to contend with that can affect humidity and condensation.[10] Equipment connected this way must tolerate large variations in electrical- and climate environment.
For more, look at table 20-1 in http://www.fordemc.com/docs/download/EMC_CS_2009rev1.pdf which is reference [10] in the Wikipedia article. Granted, that's very conservative, but a 1A 12V low drop out regulator is cheap insurance for a piece of kit like our tablets.
Interesting. If you plug in tablet and that part number into Google you get lots of familiar looking pictures:

I agree, and thanks for the info. I do ham radio and already know to not plug things in until the car is running, actually learned that from xda years back from cell phone charging. I also use Anderson Powerpoles for the connections, very highly recommend these. This does mean that given the same precautions I already follow I can make up a nice charging cable pretty easily. And I'll certainly look in to the low voltage protection, just in case.
edit:just saw the call sign, 73s!
well unfortunately I can say that this:

My husband just remembered that we bought a power converter years ago to charge a laptop while traveling in Europe.
Would this work without any problems with the Gtab?
Found the model here: http://www.crutchfield.com/S-jg9JaV...er-Pocket-Inverter-175.html?tab=detailed_info
You mean by plugging in the AC charger to it? Should work fine. The output of the stock charger is about 24W so even if it is grossly inefficient, a 140W power inverter should be fine.
Naturally, I assume no risk, yada yada yada, your mileage may vary, void where prohibited by law.
Hey, if it helps anyone at all, I bought this car adapter from the radio shack and it works well. None of the included tips worked with my Gtab, so I cut the tip off my included wall charger and using two of the adapt-a-plug connectors also available at the shack, I made it so I can use the tip on either my wall charger or my car charger. Just gotta remember to take it with me, and of course get the polarity right. Its a regulated 12 volt charger, so it reduces some of the spikes and drops from the car battery, the amperage is correct, and the on/off switch means you can wait to turn it on until after the car is started. Reduces the amount of plugging and unplugging nicely.

So I apologize for what I'm sure is a dumb question but I don't know squat about electricity.
Will this or will this NOT work with a Igo charger. Deals.woot (today only) has a 90W slimline charger that apparently outputs about 19V. The first post would lead me to believe this will not work while a subsequent one indicates it would.
I'm inclined to believe this WILL NOT work but wanted to check.

Another member reported earlier that he has researched the power management chip on the GTab and it will apparently run up 18v, this justify why many has been using the iGO Asus netbook tip successfully for so long.
Now for the woot deal, I wouldn't bother with a "refurbished" item when you can get the tried and working travel adapter for $18 (shipped) and $20 (for the version with the auto and airplane adapter) there is a confirmed tip that fits the gtab included.

Best of luck,
The first post says the top end is 18V by the data sheet. Where have you seen someone quote 20V?
I've been using an iGo netbook charger for 3 weeks without any problem. I found it on sale at Office Depot for $8 the week before they dropped the GTab price to $300. Three weeks is probably only 7 or 8 charge cycles, but I've paid attention looking for hot spots, etc. and haven't noticed anything. I don't love the stiffness of the cable, but it was $8. I'm not complaining.
My only charging "problem" is that the silly thing wakes up when it hits 100% (VEGAn-TAB Ginger). Having the screen come on at full brightness just when I'm falling asleep was funny the first time, but it's getting annoying that I keep forgetting to power it off.

the end in the tablet itself, or the end with the wire that goes to the wall?
if it's the wire end, you can get new plugs at radioshack. But requires some soldering skill to get them on there.
or you can get a universal 12-18V / 1amp charger with multiple tips.
Ok so I know many people are waiting on wireless charging. My question is, is wireless charging already here just sitting under our nose?
I haven't found any threads talking about this, so I apologize if I am wrong, but the NFC antennae is built into the battery. Could this also be the wireless charging ability unleashed by a powermat?
From: http://www.itproportal.com/2012/03/23/update-duracell-powermats-wicc-power-matters-alliance/
"Duracell Powermat's key message is that adding wireless charging is now easier than ever before. The wireless charging functionality could be built directly in the battery, as a WiCC card inserted by the manufacturer in the phone or available as an off the shelf after market accessory."
They have also shown their WICC card in the S2, so we know they are pals with Samsung. Also, Powermat has kept saying "coming this summer" for their new line of products. Perhaps the "delay" with the wireless charge kit for the S3 is actually a delay on the part of Powermat getting their new product line.
So I ask, once again...If you set the device on a powermat as is...does it charge?
No comments to this? I thought someone would at least have a powermat to squelch any thought of this I had.

That's a fantastic question and would love to know myself.
I suspect the two pins to the left of the battery are for the wireless expansion. You could be right through.
Any update on this?
These are going really CHEAP http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=360471423929&ssPageName=ADME:X:AAQ:GB:1123
ADC
it could be on the optional back cover , the two pins are for the connections , also there are claims that it can charge further away then sticking it on the dock or charging mat , i find it quite pointless if charging has to stationary , i rather just plug it in into my charger
The two pins next to the battery seems a good shout. Means Samsung can sell compatibility battery doors.
Anyone got a schematic and know how to follow the PCB wiring to see if the pins feed the charging circuit?

No, NFC is not used for wireless battery charging.
It's already been discussed and modded using a Palm Touchstone here:
http://forum.xda-developers.com/showthread.php?t=1710089
I had previously made a wireless charging car dock by combining the internals from the LG wcp-700 with an iBolt Alumina ProDock, it worked well for me but wasn't pretty and required 120v power. I had 120v power in my work truck, but I needed a solution for the wife's car, which doesn't.
So, I was finally able to pick up a couple of the Nokia dt-900 charging pads. They were out of stock everywhere around me so eBay was kind enough to provide some for me.
To start, I popped open the nokia charger and it looks like this. The board and charging coils are all one unit that is fastened with screws to the base of the pad.

}
I needed to lose the base to save the thickness, so I removed the screws and used 3m mounting tape to hold the board/coils to the face of the pad.
Then I removed the small cover plate from the car dock, again to save thickness. Never mind all the holes cut in the car dock, that was for the previous version.
Then I just used more 3m mounting tape to hold the charging par to the dock, and this is what we have. All that's left is to wire it up to 12v power, it only takes .75a so you won't need anything special. I wired off of the constant power for the stereo with an inline fuse. I wanted constant power so the phone could charge with the key off.
Not exactly elegant, but it's much better than my last version. The reason for all the thickness reduction was so that the arms of the car dock would be long enough to hold the phone with a case on it, an Otterbox Commuter case to be exact. And it works quite well, here a video of me testing with the wife's phone in the case. It's a little awkward to get in the dock because with the case, it's a very snug fit in this dock, definitely wouldn't hold anything larger.
http://youtu.be/Wl3ZFquNqJE
So, I think it worked out okay and was pretty simple to do. It's a little costly with the dock being $30 and the charger being $50, but it's worth it to me to save plugging the phone in 10 or more times a day. I have had more than a couple phones usb ports get broken from abuse over the years, so if I can reduce that risk and add some usefulness, I certainly will.
Really nice job:good: I'm curious how it does on charging? I guess what i want to know is does it actually charge well when streaming music using nav and say making a call heavy load i guess ????
Looks awesome! Nice work. Two questions though -- what brand of dock is that and where did you get it?
I'm currently using the Nokia charger in my car with a power inverter. That works fine enough for me and I intend to stick with it rather than hard wiring. However, my mounting solution leaves something to be desired. I'm using an Exomount right now. I just put the Nokia pad in between the clamps and then set the phone over it. It works okay when driving, but each time I take the phone out, the Nokia falls out as well. Would love to pick up the same mount you have.
Thanks for the kind words, as far as charging speed goes, it's about equal to the cheap car chargers. I have no problem streaming Pandora all day and taking 20-30 bluetooth calls through the stereo. I don't use navigation much, but I think if you were running nav while streaming with the screen on high brightness, you would be lucky to hold power.
The dock is from iBolt, called the Prodock Alumina. It's about $30 on Amazon right now, that and a little mounting tape is all you'll need.

I too cracked open my nokia charger just to see what the insides were like(we all do this right?). Its basically the same insides as the palm touchstones, but just much larger, in the palm charger it was a small coil, maybe 1" in diameter. So it got me thinking, as they were both basically the same coil, just exactly how hard would it be to create your own coil. Like say you use that charger, find whatever wire you would use for this application, remove the existing coils and splice in your own. I need to research a little more, mainly what type of wire is needed, but it looks like you could maybe splice into the existing wires from the nokia board and just make your own, larger coil. I would try, but I don't want to mess around too much with my $50 charger lol.
From my understanding the tech isn't too complicated, its just an alternating magnetic field between the charger and phone that is what does the actual charging. Its not some magical stuff, just a current running through a wire. Maybe the larger the coil the bigger the current need, I don't know, anyone else want to try this

I'd be interested to try something like this, trying to create a bigger "sweet spot" for the phone to rest. The Nokia version, as you all can see has 3 coils and it is pretty forgiving as to placement. The LG version on the other hand only has one coil, and in my experience was a bit temperamental about phone placement, especially with a case on it. You'd have to find out what the exact spec is for the wire, then you could freely experiment with different sized coils. I have no idea if this wire is special so someone smarter would need to figure that out.

Indeed the nokia charger has decent amount of give when it comes to placement. For future reference, the size of the sweet spot on my wooden nightstand is 6.5"x3.5", and keep in my that's all while going through what id say is probably 1/8" of wood, and the fit isn't exactly flush with the bottom of the board. The size of the spot is great for easy placement considering the DNA is just a little over 5.5"x2.5", so I have nearly 1" of space to play with.
Id like to see someone find how large the "sweet spot" is for a single coil while going through different materials too. That way we can find out how much area a single coil can cover or see if overlapping them(like the nokia) can make a difference in terms of area coverage. So that way if we ever want to create something like an entire charging surface on a desk we can know if a single large coil would be need, or just a few well placed small coils would be suffice.
I might post a picture stand, but its not pretty lol. It was just something is just decided to do on a whim, and is still a little rough, but it works really well.
Comparing the Nokia 3 coils to the LG 1 coil, it's obvious that the LG sucks.
The LG pad is probably .75" larger than the phone in each direction, but I only have about .25" of forgiveness from center. It's a pretty small sweet spot. This is with a commuter case on though, I'm sure it's better naked. Because of this, I switched to the Nokia dt-910 for the night stand, plus it holds the phone up so I can see my alarm to hit the snooze.

Curious how you are powering this JTNiggle?
I know the pad gets 12v from the included charging brick. Do you have a regulated 12v source? Or does the charging pad seem to deal with the 14+V you get while your car is running? If it can deal with the extra voltage, that'd be pretty awesome. Just a straight wire to either a CIG plug for portability or even to a fused source for permanent install.
I really want to make something like this. I never use the charging pad for many of the reasons listed around the net. Esp for end of the day things when my battery is pretty low and I want to keep using. I have found some regulated DC-DC set ups. The ones that come with multiple tips...but I havent checked to see if one will fit the charging pad.
Oh..one other question... When you assembled the charging pad, is the 3M tape between the cover and the coils? Or is it between the cover and the back of the board. If its between the cover and coils, do you think you could get it back apart again if you wanted or would it destroy the coils?

If it can deal with the extra voltage, that'd be pretty awesome. Just a straight wire to either a CIG plug for portability or even to a fused source for permanent install.
I really want to make something like this. I never use the charging pad for many of the reasons listed around the net. Esp for end of the day things when my battery is pretty low and I want to keep using. I have found some regulated DC-DC set ups. The ones that come with multiple tips...but I havent checked to see if one will fit the charging pad.
Oh..one other question... When you assembled the charging pad, is the 3M tape between the cover and the coils? Or is it between the cover and the back of the board. If its between the cover and coils, do you think you could get it back apart again if you wanted or would it destroy the coils?

It's wired direct, in line with the stereo constant power. I only see 12.6 to 13.1 volts there, the pad has had zero trouble.
The mounting tape is between the coils and the face as well as between the board and the car dock. The tape isn't that strong, it's rated for about 2lbs with a 4" strip and only used 1.5". I was able to disassemble the first version vairly easy.

I had previously made a wireless charging car dock by combining the internals from the LG wcp-700 with an iBolt Alumina ProDock, it worked well for me but wasn't pretty and required 120v power. I had 120v power in my work truck, but I needed a solution for the wife's car, which doesn't.
So, I was finally able to pick up a couple of the Nokia dt-900 charging pads. They were out of stock everywhere around me so eBay was kind enough to provide some for me.
To start, I popped open the nokia charger and it looks like this. The board and charging coils are all one unit that is fastened with screws to the base of the pad.
I needed to lose the base to save the thickness, so I removed the screws and used 3m mounting tape to hold the board/coils to the face of the pad.
Then I removed the small cover plate from the car dock, again to save thickness. Never mind all the holes cut in the car dock, that was for the previous version.
Then I just used more 3m mounting tape to hold the charging par to the dock, and this is what we have. All that's left is to wire it up to 12v power, it only takes .75a so you won't need anything special. I wired off of the constant power for the stereo with an inline fuse. I wanted constant power so the phone could charge with the key off.
Not exactly elegant, but it's much better than my last version. The reason for all the thickness reduction was so that the arms of the car dock would be long enough to hold the phone with a case on it, an Otterbox Commuter case to be exact. And it works quite well, here a video of me testing with the wife's phone in the case. It's a little awkward to get in the dock because with the case, it's a very snug fit in this dock, definitely wouldn't hold anything larger.
http://youtu.be/Wl3ZFquNqJE
So, I think it worked out okay and was pretty simple to do. It's a little costly with the dock being $30 and the charger being $50, but it's worth it to me to save plugging the phone in 10 or more times a day. I have had more than a couple phones usb ports get broken from abuse over the years, so if I can reduce that risk and add some usefulness, I certainly will.

Great Job...Glad to see more interested in expanding the wireless charging spots. have a question about you running power to constant power, did you put a power switch between that connection? The pads etc do draw power even when not in use, they just use less then say a a/c wall adapter for old way of charging.
It's like any electronic that can be controlled by a remote, even though the unit is off, it stills draws power to be on standby to be able to receive the remote command. As these pads are always looking for that Handshake to start sending power to receiver of the Wireless Charger. This is the only way it would be able to activate itself....Eventually draining your vehicle battery....
Thanks and good luck...

I'd be interested to try something like this, trying to create a bigger "sweet spot" for the phone to rest. The Nokia version, as you all can see has 3 coils and it is pretty forgiving as to placement. The LG version on the other hand only has one coil, and in my experience was a bit temperamental about phone placement, especially with a case on it. You'd have to find out what the exact spec is for the wire, then you could freely experiment with different sized coils. I have no idea if this wire is special so someone smarter would need to figure that out.

Yeah the only units that would be able to have a larger area to accept charging is the multi coiled pads. The simple basics for Induction Power is that the Receiving Coil is of Exact Size of the Transmitting Coil. This was proven by Tesla over 100 years ago and hasn't changed that Basic need since then.
The Palm Touchstone coil in battery cover is just under the size of the Charger Disc you put the phone on. The Touchstones don't have a circuit board in the design as do other Designs which is needed to do the Handshake between the receiver and Transmitter parts so that charging begins in order to make this safe and not activate by something metal etc coming in contact with the charger.
Like placing a induction abled phone on a Induction Cooktop, it will detect that it is induction and metal parts inside the phone and it may start up but then shut down which is a Good thing for your phone not becoming a melted hunk of junk...LOL...
Someone put a kila-watt device on a charging pad, and said that it drew 0 across the board until the phone was placed on it. Here's the link.
http://forums.wpcentral.com/nokia-l...ing-plate-not-power-vampire-thanks-nokia.html
Hoping that is true, because I wasnt going to put a switch on mine in the car. I still think I might just install a cig plug on mine in case I take my wifes car and want the mount. But maybe Ill get a cig plug with a switch built in so I dont have to unplug. I have a jetta...so it has all sorts of power feeds that act in different ways (always on, on with key, on for a timed period, etc).
I was just concerned about seeing the close to or over 14 volts when running. But its sounding like that might not be an issue. I measured the output of the wireless pad's power brick and it was a pretty constant 12.19 volts. I cant wait to tinker with this.

Hey, Sorry their are people out there that refuse to listen or believe Tested Facts and push their own Opinions as Facts...lol...Below I got the info for you from the Qi standard Group and other Groups also supply the Technical Specs on this Technology...Enjoy..
*********************************************************************
Wireless Power Efficiency
The energy consumption of battery chargers has two main contributors: charging efficiency and standby power consumption.
STANDBY POWER CONSUMPTION
Unfortunately, many people leave the chargers and cradles connected to mains power when the charger is not used. The standby power consumption (also called “no-load power consumption”) is significant. A simple calculation shows that power consumed in standby mode is about the same as the energy consumed when loading the battery.
We assume that many people will also keep their wireless battery chargers continuously plugged into the mains. One of our main design goals was, therefore, minimize standby power. Go low!
We did go low. In the mean time we have demonstrated a system with only 0.0001 Watt (100 µW) standby power consumption. And that is probably not the bottom.
An estimate of power consumption by wireless chargers.
WHAT ABOUT WIRELESS CHARGERS?
Our wireless chargers also contain an AC-DC power adapter. Let’s assume that is has the same efficiency (72%). Let’s also assumes that it has the same standby power (0.12 W). [footnote: Wireless chargers can have a much lower standby power, but this keeps the comparison easier.] The transfer efficiency of the wireless power link is typically 70%. And assume that the wireless charger replaces 2 wired chargers. The total energy consumption is:
•charging: 1 hours * 4 W / 72% / 70% = 7.9 Wh (we are now charging 2 devices simultaneously)
•standby (no load): 23 hours * 0.12 W = 2.8 Wh

easiest way to check if it's still receiving power while the car is off is simply place the phone on the dock and see if it charges with the engine off. if it's wired with the stereo's negative wire as well (you only stated wired to the constant power) than it wont receive power until the car is on acc. or on anyways. that should calm down anyone's fears about it draining the car's battery while you're gone.

He wanted to have power always, that's why he chose the constant-on on the head unit which is always hot to keep clock and/or memory or Like My Jeep's Infotainment that has to have a constant on so the Hard drive can shut down properly etc.
But that Kill-a-watt post he read, the guy tested it and it shows 0.00...
***************************************************
The Manual for the Kill-a-Watt ez:
Kilowatt-Hour display:
1. To display the total consumed power in Kilowatt-Hours, press the MENU key until “KWH” is indicated in the display.
2. Consumption will be displayed in Kilowatt-Hours (from 0.01 KWH to 9999 KWH). As KWH accumulate, the decimal point in the display will shift to accommodate a full reading.
*****************************************************
The problem is the reader only reads to a 0.01 kwh which this unit is for Home meter testing of kwh usage times Power company rates...
And the tester needs to read down to: From the test site and results from the lowest possible/available from their design tests:
(we have demonstrated a system with only 0.0001 Watt (100 µW) standby power consumption)
I DEF wont be wiring it to constant on power. It'll be switched. My little insert about my jetta was just me brainstorming...that car has some power circuits that are on timers. So without the keys, you can turn on the stereo for a pre-determinted time, etc. A few more options if I decided to hardwire. Having a switch on the power plug would be nice if I use my wife's car, as both her cig lighters are constant on.
In the end...Ill be wiring mine to a plug so I can move it from car to car easily. Just like a GPS. I just picked up a regulated DC-DC adapter that Im going to test. Says it holds 12 via IC control, and it comes with a tip that SHOULD plug right into the power pad. We'll see. I can always fall back on wiring it straight.
And the link I posted...That guy's test is still pretty useful. Its showing that its not exactly sapping energy when not in use. I guess some other charger power bricks pull some measurable power when left plugged in..? I think .0001 watts is pretty insignificant dont you? Even if wired straight to the battery it would take quite a while to drain it any significant amount. Unless Im misunderstanding things...which happens more than I like to admit
Regardless, it wont be wired to any constant source, at least in my car. So it should be good. I cant wait to get my mount and try to fit everything together. Little projects like this are fun!

Yeah just find the RAP Fuse etc, (Retain Accessory Power) and connect their...It works great. You may even have the Option like My Jeep does and change the Time-out minutes to suit your needs.....Yeah what he did was Great, and I did give him a Compliment on his work, problem is just that the Kill-a-Watt is for A/C power meter tests/results and the device being tested is D/C power...kWh is a measure of energy, whilst kW is a measure of power...
•a kW is 1000 W and a W is 0.001 kW;
•a kWh is 1000 Wh and a Wh is 0.001 kWh;
•a MW (megawatt) is 1000 kW and a kW is 0.001 MW;
•a MWh (megawatt hour) is 1000 kWh and a kWh is 0.001 MWh
Yeah this is Fun Stuff isn't it???/ LOL...right now I'm doing custom install of a double charger and a single charger, wireless chargers, in my jeep. I'm Hiding the double charger to the underside of the tray inside the center Console and single charger underside of the Tray on Driver's side. You won't be able to see that their is a charger in each location....
Like to see what you do when you get it up and going....

I do not have a switch for this charger wired in, I did not see the need. The amount of power that this unit draws while not charging is very minimal and the vehicle is driven daily, so we have not had any trouble. I need to make a second one now to put back in my work truck, where I will just wire in line with the existing 12v accessory outlets as they are on 100% of the time. I just like being able to park the car and leave the phone charging if I need for a few minutes or an hour if necessary. If you have to leave the key on then you have a whole bunch of extra accessories trying to run at the same time and then you may kill your car battery trying to boost your cell battery,
For multi coil wireless chargers, I thing we will eventually see them built into all kinds of things, at least I hope so. We have that JBL charging speaker, which is way overpriced, but a more basic clock radio with charging coils on top would be nice. Not just one spot, but say the whole top had coils in it and you could set the phone anywhere. Laptops could have an area below the number pad with a coil or 3 in it, that would be great too. It seems to be useful enough that a few people here have cut wireless charger into their desk or night stands, obviously there is a desire for the tech to grow, so I'm sure it will only keep growing in the near future. I think I may end up building one into the kitchen counter for the wife, she likes to use the phone for recipes and music, so it would be great if I can find a neutral spot that isn't too likely to get wet.

Funny enough, one of them is the same one you just posted, just a different brand name. Worked good for my Nexus 5, but my LG G3 usually just stays at the current level when I put it on there with Ingress or Waze plus BT Streaming going on. If it is hot out it loses charge slowly.

Does your DigiYes consistently charge your phone? I have one of the DigiYes models, but I'm finding it frequently stops charging, often within seconds of beginning charging, though sometimes it lasts a few minutes before giving up. I always get the "Wireless Charging" message on the display, never the "slow charging" warning.
I tried swapping their 2.1A cigarette lighter adapter for an Anker 2.4A charger -- same deal. Tried adjusting the vertical position in the charger -- sometimes seems to last a little longer before giving up, but generally doesn't help at all. When it stops charging, the blue light stays on (rather than going back to green).
When it does charge, I seem to get a decent charge current out of it. Very confusing, and probably going to get shipped back.
Edit: it seems to drop out less when charging from wall power, though it still happens -- perhaps correlated with greater power demands on the phone (Google Earth).
I did state above that it charges my phone, but if Navigation and BT Streaming is going on it keeps it at a steady level, or if hot discharges slowly.
If you don't have a 3 coil QI charger, positioning is very important, if it charges and stops, it is a positioning issue for sure.
Changing to a higher amperage charger won't help, as Qi only puts out so much. The new Qi standard coming out should fix this for us though, it transmits 2 amps I think, and has more distance so positioning shouldn't matter AS much.

Does the DigiYes disconnect constantly like the one I have? Or no?
Nope.
My other one did, but after adjusting how high it sat with the bottom brace that problem went away.
My air dock keeps the phone at a steady charge while running navigstion, bluetooth (aptx) via stock music app, and 100% brightness. The thermal protection activates eventually and lowers the brightness to 90%, and then it starts to very slowly charge. It charges fast if not running anything.
Also, you don't need 3 charging coils. My powerbot disk style charger easily works without worrying about position. I opened it up and the whole thing (~2.5") is one big coil. The air dock works well too, but I haven't opened it up.

It works perfectly fine. Does yours use both magnets and the suction pad? I believe they were separate options in one development point. Also, my car was dusty and it did get some dust on the pad which made it not hold, but wiping it with a damp cloth and letting it dry fixed that issue.

My DigiYes 3 coil frequently disconnects, sometimes in a constant connect-disconnect loop. Other times it holds for a while. It seemed to do better when I put it on a higher amperage charger than it came with, along with the original G3 cable. However this could be coincidence. When it does charge, the charging rate is comparable to any of my desktop qi chargers.

Yes you can. But only Huawei has the 15w option. Others are limited to 5w-10w. At least I believe that's the case.
I just received my wireless charger yesterday.
I know some alternatives exist, but at least in Canada, 15W Qi charging options are as expensive as this charger was, so I chose the Huawei proprietary tech for the same price.
I am loving this wireless charger. I finally have quick wireless charging, and the pad feels premium.

I'm quite sure Xiaomi has 20w
Well, I ordered one of these from FastTech, and it arrived about a week ago. Amazingly quick shipping considering I bought about a dozen little el cheapo goodies and paid about $2 for the postage. The charging pad is genuine Huawei, in general anything on FastTech that outright claims to be genuine is. It came in a very nondescript tough plastic bag that held a white sealed box. Inside there is a meaningless tiny little pamphlet in Chinese, but why would you need any information anyway? As was mentioned, it doesn't come with a power supply - again, why would it? I crammed my official charging cable into it, works fine. The charging pad is quite a bit smaller than I expected, I guess it doesn't need to be anything more than it is - I would say about 2.75" in diameter and about half an inch thick. The surface is very 'grippy', I wish the TPU case that came with the phone was this sticky. Speaking of which, I throw my phone on the pad with the TPU case and it works fine. In fact, just in the name of science I just tried seeing how thick of material the charger would still work through, and it easily triggers through even 1/8" of paper - so this will work with *any* case that isn't made out of metal.
At first I thought that the placement was *extremely* finicky, because sometimes it seemed like it wouldn't trigger. I've learned since that it just takes a second or two sometimes no matter where you put it, so you just learn to trust it. The phone does have to be somewhat 'centered', but it isn't crazy specific. So, you plop your phone down and the nice green bubbly animation pops up with a pleasant sound, and the icon in the center shows that it is charging via lethal levels of radiation rather than safely through a wire. There is a very small LED under the lip of the pad, that lights up when it is charging. Obviously the LED on the phone will either be green or strobing for a notification while this is going on too. As far as charging speed goes, I haven't done any rigorous testing of any kind but it is most definitely not 'slow'. You put it down, and when you pick it up it has charged up enough that I have never thought "hmm, this is slow". Yeah, I know - real scientific. Oh, and the phone gets 'barely warm' when charging, and I do mean 'barely warm'. This is good, I've heard some combos out there result in a cooking hot phone - and that isn't good for anything.
Otherwise, not much to say. It is very, very nice not to have to plug my phone in - wearing out a charging port is an actual worry, and this way the bottom speaker isn't muffled to nothingness (a strange move, but when you take aggressive hyper efficient space and waterproofing into account it makes sense). One thing to mention, you obviously can't use your phone while it is charging. I mean you *could*, but you won't. If I had to gripe about anything, it is that the pad is a little thicker than I would like. It doesn't hurt anything, but if you have it teetering up on a high spot or something you will need to be a little wary about how you place your phone.
On a side note, not that anyone really 'needs' it in the real world, but don't forget we do have wireless charging in reverse. From reading up on it, the placement between two phones is *extremely* picky, and I would say that if both phones had a case it probably wouldn't work. The other thing they mentioned is that once you initiate a reverse charge, any movement between the two phones of any kind will break the connection - and it is a pain to get going again. Did you know we also have the option to charge something else via the Type C port? It is listed in the settings, I haven't seen that mentioned anywhere. That would be crazy useful - especially since we have SO much battery to spare. Think about it, you could charge wireless earbuds, bluetooth speakers, whatever. No idea at what rate it would charge (theoretically it could be fairly substantial) and of course the kind of cable you would need to do anything with this doesn't really exist... I am going to patch together a Type C to one of those 'multi-pronged charging ends', just to try this out. I have a very neat cable with one end that with one fixed end can fit both Micro-USB and Lightning ports - no one believes me, and honestly I didn't believe it myself at first either. When you eyeball it you think "now why aren't there more of these out there?"
Anyway, for the $20 this charging pad is a no brainer. It is legit, authentic, and works like a charm. One last thing - I swear I can feel the thing radiating from a foot away. I know that is 'impossible' given the inverse square law, but I'm not kidding.

Excellent and very helpful review, thank you very much !!!
@kaibosh99
Did the LED and cooling fan switch off automatically when the M20P was fully charged?
So does it show on the screen that it's fast changing?
