Is there any kind of portable charger for HTC touch pro 2 battery which can charge battery via USB?
For example to charge battery from computer (like phone charges the battery).

But I am not talking about cradle chargers which can accommodate battery and phone at the same time.
and also not these chargers, they just support the USB as an output not as input!
So with this charger you can charge battery and phone only with AC power.
OK, gotta ask
Why you want this? You can charge the phone directly with a USB to USB-mini cable, and if you have a laptop and use it for any length of time you will plug it in (so one of the cheap plug in chargers would work for this purpose).
For the above reasons I don't think anyone has made a device such as you describe.

Thanks for reply.
I want this kind of charger to charge batteries with some cheap and non-reliable sources during traveling.
Like:
If I charge mobile pone directly I am afraid that the phone will be danaged.
whats wrong with a cradle charger for that? just because it has the dock for the phone doesnt mean you have to use it, and you can get the cradles for cheap on ebay, and ive never seen one just for charging batteries
I was buying some stuff and found this

I'm afraid your link does not have the charger itself, just the accessory.

OK, you must be going to some rough country where there may not be power, correct? I think you may be stuck with simply powering the phone via the USB cable. So long as your manual hand crank only puts out the standard USB voltage, you should be fine.
He didn't want the charger...he's using the hard crank
if you have a multimeter you can check the voltage of the hand crank to determine if its safe to charge the phone directly

Nice diagram you drew out that CLEARLY spells out what you are looking for. Not sure how other people could not understand what you are looking for, as that's something I require for any new phone platform I use. The ability to charge a spare battery from USB power (5v, 500ma+) for when you are somewhere you need to swap batteries and keep the spare charged at all times, etc.
So to answer the OPs original inquiry:
1. HTC OEM spare battery charger, model "HTC BC S300". Uses USB power to charge the spare battery as it has no direct AC input.
2. Seidio's charger that allows for AC or USB powered charging of a spare battery, model "BD3-BCSI3HTP2-BK"
This one is pretty decent as you have two options to power the charger. I can confirm it works either way. The other benefit is you can just replace the charging plate to support other battery types. I bring this charger on any extended trip I go on and keep one in my luggage at all times.
You'll have to google for the model numbers I put in quotes as I do not have enough posts to include URLs in my replies yet. The first hit you get on google should show the relevant info.
As for how you obtain your USB power safely, that's a separate issue that you are on your own.

From the website it appears the HTC BC S300 is for the Touch Diamond or Touch Pro.
http://www.mobihand.com/productaccessories.asp?id=29936&n=HTC-External-Battery-Charger-(BC-S300)
However, the other model should work, but the picture indicates that one would have to buy a male-to-male USB cable rather than the normal A to B cable for it to charge. I think this model would be the one to use.

35 dollars is pretty steep for that IMO
and for the record, i understood what he wants, i was just curios why the combo dock+battery charger was unacceptable, since it has a USB powered battery charger (at least the one i got did, 25 dollars shipped on ebay, even came with a second battery, much better than the 35 for the OEM battery charger)

Oops, I just edited the post you quote. That one was for the original Touch Pro, NOT the TP2.
He wants one that will charge FROM the USB port, evidently so that he can use a portable USB hand-powered generator to charge the batteries. The ones on E-bay will output USB power, but not charge a battery FROM the USB power.
Are you saying you found an e-bay model that charges from the USB? Can you post a link?

No worries.
The Touch Diamond and Pro use the same default 1500mah battery the TP2's do. So the HTC OEM spare battery charger would work fine. That's one thing I love about HTC is they try to maintain the same type of batteries in most of their model line ups. Even their new Sprint EVO phone uses the same battery, nice!
That Seidio product link you listed is the same as the model number I posted. Good point on the cable. You would need a male to male type A USB cable to run from USB power. I carry various USB adapter plugs when I use it.
As for defaultdotxbe's post, seems you have the same concerns... he/she may have overlooked that the OP wanted a charger that runs off USB power. I have yet to see any of the combo docks on fleabay run strictly off USB vs providing USB power.

I guess it is the angle of the picture on the first battery. It is squished flat, and I thought the contacts were on the side rather than the bottom.

As I see the cradle charger is the best solution from the point of price and practice.
Just I was expecting something simplier and respectively cheaper than that cradle charger but as I see there is no cheaper.

its actually a 10 cent capacitor (or battery) that makes any charger reliable, like my 2 dollar car charger
like this one for example: http://inspectusa.com/emergency-han...r-vzl3883-with-flashlight-compass-p-1109.html
the cranking isnt putting voltage over the USB directly, it charges a button cell battery which in turn charges the phone, so it works like a UPS for a computer system and regulates the voltage going to the phone, so its safe to charge directly (im actually thinking of buying that one myself, lol)
@stevedebi
the only cradle ive ever used was for my old sprint mogul and it charged the battery through USB so i assumed all cradles worked this way
defaultdotxbe
I found cheaper solution:
it applies USB power directly on moving pins to charge battery.
As usb voltage is compatible for HTC TP2 battery charging it will work as portable usb charger.

Hi all,
Just got my hands on my new Asus Transformer. Just getting to grips with the USB 3.0 charging problems, etc... Sorry for not reading through the other posts in there entirity, in a bit of a rush to go on holidays and need mobile charging!
I need to keep the device alive and charging in the car (kids, angry birds, i'm sure you understand!).
What can I use? I thought my 12v cigar to USB would work as with my old android phone, but it clearly doesnt as it doesnt charge while the device is on.
What are my current options for immediate purchase here in the UK?
Thanks in advance.
Hi
There are no options, at the moment, either here in the UK or elsewhere.....
....except if you make your own charger....cable.....trouble is that two things : first, the 40-pin proprietary plug that connects to the TF/dock; these are not available anywhere yet and secondly that regular 12v USB chargers do not chuch out anywhere near enough juice for the TF
ASUS UK are in the process of getting TF accessories available see here .... but that's it, unless you want to make your own.
Your only option right now is to get a Car power inverter and use the wall charger.

I'd definately have a go at making my own, if only I could get the connectors! As for the 12v USB adaptors, im sure I could make some mods to get enough power! ;-)

check out this post of mine in the "short cable" thread:
http://forum.xda-developers.com/showthread.php?p=16320775#post16320775
you can do it for about £27 with generally-available parts.
goes without saying i hope ---- triple-check polarities/ voltages etc. before plugging anything in!

To sum up that post, all you need is any car charger that puts out close to 15v at 2amps or more. Then you put a regular USB female port on the end of it (either through an adapter or by wiring it up directly). Then you use the standard ASUS cable to connect it to your tablet.

Most car's electrical systems are at 14-14.5V when the car is running. I've seen posts that say the TF will start charging at 11V, so even with the car off, there should be enough voltage to charge directly from the car's electrical system. Obviously a fuse is recommended, and voltage regulation would be nice, but shouldn't be necessary.
I haven't had the need to charge my TF in the car yet, but I plan to put a usb 3.0 socket in my car, and use a switch, or watch pin 7 for ground(or whichever it was, will double-check obviously), to toggle between a 5V supply and the car's 12V system.
Hi, thanks for the info. Do we know the pinout for the female USB socket? Thanks.

You'll be connecting ground to pin 4 and +11-15V to pin 1. Do not use with normal USB devices, it will supply the 11-15V to the same pin that normal USB uses for +5V, so it's a fairly certain instant-fry. Change pin 1 to 5V for normal devices. To switch between 5V and ~15V, I plan on using the same method the wall charger uses, watching for ground on pin 7(pin number needs verification). If you switch it manually, or don't switch at all, you can use a standard USB 2.0 socket instead of the 3.0(The pic is 2.0, 3.0 has 5 extra pins behind the first 4, there will be fewer pins to get in your way when soldering).
If you buy one of these http://www.amazon.com/Portable-Inve..._1?s=automotive&ie=UTF8&qid=1312550809&sr=1-1
Then just plug the Asus charging power block into that. This looks like the easiest solution right now.
You don't need a 175 watt one, that's just the first one i saw on amazon. The power block has a max of 2A rating with 15v so that is only 30 watts(v * a = w).

Nice. Lots of 110v 75 watt items on ebay, too.
75W 12V DC To 110V/220V Power Inverter Car Adapter USB
Car AC Power Inverter 150W Pop-can 12V To 120V w/USBH42 (This one looks pretty cool in my opinion)
I have no idea if these will work with TF101. Has anyone tried yet?
It should work.
I used to have this one: http://www.amazon.com/Cobra-CPI-150-Micro-150-Inverter/dp/B000F6NULK/ref=cm_cr_pr_product_top
Small enough to carry around + airplane adapter.
An inverter is a good solution for charger the TF without much fuss. If someone wants to wire something directly to the cig lighter, be sure to unplug your TF when starting the car to avoid voltage spikes.

Find one with high and low voltage protection and you don't have to worry about spikes.

He said that in regard to directly wiring to the car's electrical system, not an inverter. Are you suggesting he buy a car with over/under voltage protection?
P.S. @ zepheris.hk
Since the TF expects 15V(and the internal regulator should be able to handle up to 37v for a couple seconds), I doubt you need to worry about spikes from a direct connection to the car's system. Besides, I've never seen a car that spikes when starting. You'd notice all the lights get brighter, instead of dimming as they normally do(from the voltage sag induced by the starter's amp draw). That isn't to say that there can't be other spikes if something is wrong with your electrical system though. I recommend a resistor to limit amperage at the very least, if you're brave, the internal regulator should be able to handle any over/reverse voltage(within reason) as long as there's current limiting.

110v inverters are all the same, basically, so as long as it meets your wattage requirements(30W) it will work. I suggest 90-100W though so you can charge a laptop also, if needed. Most laptops are 60-100W.
My experience so far...
Yesterday on a long journey I used a 175w 12vdc - 230vac inverter with the original mains adaptor that comes with the TF. Can't link to the inverter, I bought it a while ago from Maplin (UK) and hadnt used it.
All worked fine.
The TF AC adaptor got a bit warm, slightly more than usual, but nothing to get worried about. The charging went fine, I couldnt use it permanently connected and in use because of the stupid length of the cable and my 3.0 USB extension hadnt arrived before we set off.
I've just bought another 3.0 USB cable and a cigar lighter plug and will attempt to connect it up by using the (approx.) 13.8vdc directly from the cigar outlet in my car. I can't see why that wont work?
I might just wait until the warrantly company confirm my TF is on their database before I attempt this, but will post back soon.
Thansk for all the tips and info guys.

Like I said, the cigar outlet should work fine, but you don't need a 3.0 cable, you can just use a 2.0 to simplify the wiring, and using a 3.0 cable won't protect other devices from overvoltage anyways.
I recommend a 7.5 Ohm resistor to limit the amperage to 2 amps: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=TR50JBD7R50-ND
This one is a 50W, so it should be able to handle 2 amps without heatsinking.
Long term, I'd suggest adding a decoupling capacitor to get rid of some of the noise from the car's electrical system, something like:http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=P12389-ND.
For just one trip though, you should be fine without any added protection. I would suggest the resistor though, as the outlet will give it up to about 10 amps, and I don't know if the internal regulator in the TF is limited by itself, or by the charger(which only puts out 2 amps). If you don't use a resistor, watch the battery/case temperature like a hawk, especially when the battery is being charged from a very low level(0-25%), this is the highest draw portion of the charging cycle, and consequently, the hottest.
Transformer needs 1.5A output cigarette lighter. If you can find one, you're golden.
I bought a Griffin Powerjolt Dual Micro adapter (http://www.amazon.com/gp/product/B0042B9U8Q/ref=oh_o01_s00_i00_details). It supposedly can do 1A on each port. I modded it as the commenters on Amazon suggested (open up, solder the middle pins on each side together so that it's recognized as an AC charger rather than USB).
Both my Flyer (Leedroid HC rom) and Evo 4G see it correctly as an AC charger. However, monitoring the current via Elixir says it's not getting near 1A. For example, the flyer was showing somewhere between -500ma and -700ma while unplugged (GPS on, wifi tethering). When I plugged it into this charger, it was showing around -50ma. So it's getting only around 600ma of juice, not 1000ma.
Testing my Evo on the charger showed the same.
Using an actual HTC AC charger (old one, from my TouchPro2 days, but rated for 5V 1A) both devices indicate they're getting somewhere around 900ma, much more like I'd expect.
So is this charger just crap? Or is that normal for a car 1A charger? I'm debating getting something else - ideally one of the chargers that claims to have both a 2.1A port and a 1A port, since I want to run both the flyer and evo (for tethering) in the car. Got suggestions on any that are good? Small would be best since a big charger blocks my cupholder
You'll be best off getting a small 12 /120 inverter. The magic is in the HTC charging cord connector not the power supply. Just use the inverter with the HTC wall wart. It produces 9v at 1.2 A. Since the Flyer has two batteries, it really needs more than 5v
That just seems like such a ridiculous way to do it - 12V in car, converted to 120v AC, then BACK to DC at 9V...
I tried another USB adapter that I had lying around, a really really cheapo one that claimed to be 1A. Well, my phone shows it's getting around 900ma from it. So not too bad, and certainly better than the name brand that I modified. So looks like I'm back to the hunt... either a dual-usb 1A each adapter, or better yet, a 2.1A/1A dual adapter that can actually output that much.
But still, even the modded one isn't too bad. at only 50ma net drain, that flyer battery would last longer in the car than I will

I think there is easier way. Griffin 2A car charger has chip inside, it can give up to 20 or 30V and 3A! Voltage is regulated by changing only one resistor. I have datasheet somewhwere, but you can google. Datasheet will explain what resistor and wat value is needed for 9V.
So changing resistor should be enough, but I am not shure 100% because I do not know if Flyers original charger uses specific pins or the same usb pins for charging
Sent from my HTC Flyer P510e using Tapatalk
Well, you don't really want to change voltage I don't think. I know the official charger does 9V over the same pins as the usual microUSB 5 pins, but I don't know for sure if the flyer has to do anything special to know 9V is coming. Or if the pinout is different.
So for now, I'm planning to just get an ipad-type 2A 5V charger, mod it (since the ipad doesn't use standard methods of knowing the charger can do more than 500ma), and see how that works.
I'm not terribly concerned about CHARGING the flyer in teh car. I just don't want to lose too much battery while on a long drive. So even a true 1A charger would be fine - that's more than the flyer draws. I just thikn the charger I got isn't actually doing what it says.

You are not right. It gives up to 3A, but voltage is too low for Flyer. To charge properly Flyer needs 9V voltage and up to 1.2A. If voltage will be only 5v - you never will never get 1A with flyer. Tested various 1 or 2A chargers (even genuine Iphone) with data pins connected. And i also said that griffin circuitry is capable of giving more than 1A. HTC HD2, draws its maximum ~800mA from griffin, so you theory would say that Flyer can draw more than 500mA too but it doesn't so it is due to voltage or special pins.

The flyer does not NEED 9V - it's just faster. Heck, the thing came w/ a USB cable which is only 5V and it will charge, just not as fast.
I've got some REALLY cheap USB car chargers (look like this http://www.aliexpress.com/product-f...obile-Cell-Phone-White-Color-wholesalers.html and I got them for like a buck a piece). Sticker says it'll do 1A. On both my Evo and my Flyer, I get around 900-950ma out of it. So yes, the flyer can indeed draw 1A from a charger that can do it.
I think the charger I've got (the one in the original post) is just crappy. I ordered another model (http://www.amazon.com/gp/product/B0056VNVV8) which claims to have a 2A port and a 1A port. I'll try it out, don't expect it to actually do that stock since the ipad is the main device that uses 2A and uses proprietary methods to signal that. Then I'll open it up and short the data pins and see what I get. HOPEFULLY I can pull enough juice from it to keep both the flyer and evo happy.

Yes, Flyer does not need 9v, but only when charged from usb port. In USB case Flyer identifies power source as usb and do not try to get more than than 500mA. By shortening data pins we make Flyer identify power source as AC, so it thinks that it draws power from charger ( it expects 9V 1.62A) so charging from 5V 2A doesn't work as from 9V source. I have already tried Samsung 2A charger, Griffin car charger 2A, iPhone 1A charger.... (With data pins shortened) Flyer identifies them as AC source but current do not rise more than 500mA and only when power/screen off. When on - I think charging do not work because Battery Monitor Pro shows opposite current flow (discharge).
So:
a) Your charger is not crappy...
b) 5v*2A=10W is less than 9V*1.62A=14.58W

Not sure why you had no luck w/ all those chargers. I've used both the flyer and my evo 4g to test, monitored w/ elixir (showing the ma flow either direction, use or charging), and several adapters both AC and car.
My flyer absolutely could draw 900ma or more out of the cheapo car charger at 5V. That's plenty to keep it charged and even add some charge slowly (about 300ma gain) while using GPS, full bright screen, and tethered over wifi to my phone.
The problem is that is a single USB charger, and my car only has 1 cig lighter port. So I'm looking for a dual-USB charger. I'll post the results of the new one that's on the way.
i used a Griffin USB charger in my car for a while, and it didn't do a bad job. I think it was rated as 2.1 amps. I had to try several USB-to-microUSB cords to find one that was wired for charging, and not just data transfer/trickle charge.
Finally, I gave in and bought the proprietary HTC car-charger from Sprint, and it works great! If I turn on everything I can (mobile data, wifi, gps, screen brightness, nav app, etc) it will keep my EVO View running great and charge the tablet in fairly short order.
Ok, update. Got my Bracketron adapter last night. Looks like this:

First I tried my HTC Evo 4G phone. From the 1A port, it pulled a great 1A charge. From the 2.1A, it shows usb charging and only 500ma. That was as I expected, since the only device most people know of that uses 2A is ipad and it uses stupid proprietary methods to detect the charger's abilities.
Next I hooked the flyer up. No surprise, it showed the same result from the 2A port. But from the 1A, it said AC charge, but only drew 500ma. So that's the same thing linuxis saw, that the flyer would only pull half amp. Not sure how/why it gets 900 from my other charger...
I also opened up this charger. Looks well built inside. However, I can't solder the data pins on the 2A jack cause there's not room. A long, thin soldering iron could do it, but I've only got a normal tip. So I think I'll try hacking up a usb cable and try that, see if I can pull more juice from this thing. Otherwise, I'll stick to my ultra-cheapo adapter and get a 2 port 12v adapter (you know, turns one lighter socket into 2) to run two chargers that way.
Hate to see you torture yourself over this.
$10,
120v @ 100w + 5v @ 500 ma. from one 12v socket
Attached wall wart and USB cable
Charge and power Flyer /View + cell phone and add in a laptop if you want.
Problem solved.
Ah, this isn't torture. this is playing around with something. Yep, there's a simple solution, but it's ugly and crude and wouldn't fit my car very well (stupid car has the socket right under the cupholders, so using that would mean I couldn't open the cupholders at all, so I'd need a 12v extension to put the inverter on the floor).
So I'm playing around with finding a better solution... and sharing my findings so others can learn from my lessons
OK, that's good. I thought you were in imminent need of a solution.
Onward and upward.
Im sorry but when will the auto industry wakeup and provide a better accessory power port? Do we really need that clumsy, pita, half ass, eyesore in our cars? How about a multi pin port where the cable jumps pins to get 12, 9, 5 and 3 volts.? How about auto sensing like some generic laptop chargers? Come on Europe, you did ok with mico usb ports on phones can you go after the auto industry now. I would gladly pay $100 to have a multivoltage port in the dash and the trunk/back. I know some cars had an inverter option built in as an option.
I wonder if there is a dev could come to the rescue. I remember some rom developers making their roms charge faster and also making them charge to 100%.
Anyone know where I can find the special plug that HTC used for the charger? I already have a few 9volt chargers collecting dust, would be nice to make one work for the cost of a plug?
Keep dreaming the auto makers are never going to provide anything like that. That's why smart phone makers standardize to 5v 500ma. Except for those that don't, like HTC...LOL
Tablets are more power hungry. HTC choose to use 2 x 3.6v batteries rather than on big ass battery, probably because they had them laying around and because it's cheaper and easier to run batteries in series and do 9v @ 1.2A than to do 5v at 2A . Therefore the need for 9v for fast charging.
As far as the HTC connector its only available from HTC and I don't think they sell them to anyone.

Ok, is there anything in software that affects charging? There's gotta be something at some level, since for example it won't charge while going thru some of the rooting/flashing stuff.
I ask because I retried my cheapo charger and now get just 500ma from it even though it's recognized as AC charger. I KNOW that a week ago it was giving me 800-900ma. But I've also flashed my flyer a dozen times in between, and I have no idea what I was running when I did that earlier test.
timropp said:
However, monitoring the current via Elixir says it's not getting near 1A. For example, the flyer was showing somewhere between -500ma and -700ma while unplugged (GPS on, wifi tethering). When I plugged it into this charger, it was showing around -50ma. So it's getting only around 600ma of juice, not 1000ma.

I just posted this in my other thread Information on charging the note, but that thread is really lengthy and I thought this was worth mentioning in its own thread for anyone who might be looking for a good car charger, but doesn't want to read 8 pages of other information.
I had been looking for good one, and started with the motorola charger that I've seen recommended a few times. It's cheap, nicely made, and does have the data pins shorted, but for me, it didn't meet my needs because when using GPS in the car. With the screen on, the phone actually discharged and did not charge. It discharged at about 6% per hour. This is not surprising because when measured, it does not put out the max current that the note can accept (it puts out about 850mA of charging current via my measurements).This charger, on the other hand, puts out the max charging current your note can take (1000mA). I have verified this. When using GPS with the screen on, on my note at least, it actually charges the phone at a rate of ~3%/hour instead of discharging. It will even charge the phone if you are using GPS + screen on + also streaming music (ie pandora). That 150mA difference may not seem like much, but for me, it's the difference between discharging or actually charging the phone while using GPS.
A couple of notes... this charger does not come with a cable, so you'll need a generic usb type a to mirco usb cable. Nothing special is needed in the cable... you can get a "charge only" or a data version, any cable will be fine. Amazon has some very inexpensive ones with low shipping costs if you search. There are two ports on the charger, clearly marked on the charger itself, a 1A port and a 2A port. The 2A port will NOT charge your note at the AC charge rate as the data pins are not shorted -- it will charge at 500mA, and your phone WILL discharge instead of charge if you are using this port with GPS, etc. So ignore the 2A port unless you have an iDevice you want to charge with it. The 1A port, however, WILL charge your note at the AC charge rate, and DOES put out the rated 1A. This is the port you want to be using for your Note.
So, if anyone is looking for a good charger for the car, that's it. The only negative thing I have to say about it (so far) is that it is a little bit wobbly once seated in the cigarette lighter. Not enough to come out or cause any problems or anything, but enough to be annoying (to me). Nothing a little electrical tape (or any tape) can't fix quickly and easily, though, if it bothers you enough.

Personally I like the Motorola Chargers as they have a nice wound cord, although they only charge one device.

That is the other charger I was talking about that is not nearly as good as the one I'm suggesting. With that charger, if you use GPS while the screen is on, your battery will discharge instead of charge. Even without GPS or the screen on, in the best case scenario, it will still charge slower than the one I've recommended. If you're OK with that, then yes I suppose it's an OK charger. It's cheap, looks pretty cool, and seems well built. But for my needs for a charger, I need a) the fastest charger available, and b) for a car charger, I need one that lets me use the GPS on my phone without losing battery life. That's why I searched and found the one I'm recommending.
I personally hate the wound cord because it puts tension on the phone if you try to use it beyond the wound range (which I almost always seem to do), but that's a totally personal preference. The cord is always fighting me when I'm typing on my phone while driving (Not that I do that )

WHAT? Nonsense. First off, the phone is not going to draw more than 1A, and that is a 1A charger. Second, with the big screen on this thing at high power with GPS it's not too surprising if it just maintains its current charge, but in my week of owning my Note I know it does charge while it's on it, and my Nexus One charged on it just fine.
And the cord is very long, not sure where you're plugging your phone in..
OP said he tested the Motorola charger and it only put out 850mA, not 1A. Another poster in a different thread mentioned that his phone still discharged while using that specific car charger as well. So with heavy use it looks like it is possible for the phone to still discharge with the Motorola charger.
Thanks for the info. Had a Verizon car charger for my defunct droid razr and wasn't giving out enough juice to keep the Note running. Heck, it wasn't even able to keep the droid running.
Will look into the ones mentioned here.

I'm not saying the the phone is drawing more than 1A. I'm saying that the motorola charger does not provide the full 950mA it claims (only provides 850mA), and this one I'm recommeding DOES put out the full 1A it claims. Either way, though, there's one thing I know for sure: the one I've recommended above charges faster than the motorola one, and allows your phone to charge in some scenarios where the motorola one does not. It is a better charger, from the aspect of actually charging the phone. The motorola charger might be fine for a lot of people. 850mA is still a good rate of charge, but unfortunately is just shy of being able to maintain or actually increase the state of charge of your note's battery under a common (for a lot of people) scenario in the car -- using the GPS with the screen on. If, however, the motorola charger is working perfectly for you, that's great. I don't care if you buy the other charger or not, I have no affiliation with the company or amazon or anything, I'm just providing the data so everyone can make an informed decision.
The wound cord thing is totally personal preference, I'm not gonna argue that one way or another.

Just FYI I cannot confirm that this charger has the data lines shorted, so you may not charge at the full ac charge rate. Just because it says 1.8A doesn't mean anything. If it does not short the data lines, it will charge at 500mA (half the rate of the OEM AC charger), whether it's rated at 1A, 1.8A, or 1,000,000A.. Sorry if you already knew this, I just don't want any more people getting confused thinking that as long as the charger says it's rated at 1A+ that they will be charging at the full 1A. This is not the case with our Notes (or most/all? Samsung phones). No charger can or will charge faster than your OEM charger, unless your OEM charger is defective. The speed can only be matched, not exceeded.
Here's a scenario using the Motorola charger that is baffling me. I agree with the OP...using my Note with GPS and playing mp3 music at the same time does discharge the oem battery at a slow rate. But if I follow the same scenario, but use a cheap Hyperion 2600mah battery in place of the Samsung oem battery, it actually charges during use! Not fast, only about 3% an hour, but that beats a discharge situation! Why is this?

Great informative post OP! Thanks! I was actually looking into this yesterday and your post is exactly correct. I currently have two Motorola chargers and yup, the Note discharges when using the GPS. I was looking into a new charger and ordered the exact same one you mentioned (in white).
What is surprising to me though is how you mentioned the 2A plug will not output the proper amp, so I have to use the 1A port instead? Do you know why they made it this way? It is just weird how they designed it.
Thanks!

they are all over Ebay now for around $13. got one today and it works great. These chargers don't have a USB port the cable is connected directly to the plug. much better than paying the $40 for another charger.
Amazon has similar items. Waiting on mine in the mail.

The power of the Internet is that one can link to things.....So...share that link!
I bought one on ebay for $9.50 coming from China. Made my touch screen go haywire. This one has the usb end so I can use my stock usb cable to it. I wanted to get it to extend my cable. I've also seen one with the 40pin charging connector on ebay and amazon that some reviewers mention had the same effect on touch screen. You can test yours by not touching the tablet and just use your finger across the screen. Once you touch the tablet with the other hand it grounds the tablet and works fine. I'm not sure I would trust these chargers not to damage the tablet eventually since they are not properly grounded. Here's a video i sent to the seller who promptly gave me a refund. So just be careful...

Had the same happen with mine. Has a fixed 40 pin plug. Told the seller and he send me another one -guess what - same thing.
Be careful ordering these. They have issue as shown.
Given that I spent $500 on the tablet, and another $150 on my dock I don't know it is really worthwhile to skimp when it comes to buying a charger for my Prime.
These off-brand Chinese chargers have zero quality control and there is no way to know what voltage they are actually delivering to the tablet. They could be destroying your tablet's battery.
IMO, if you need an extra charging cable you are better off just spending the $30 on an original Asus TF101/201 charging adapter.
Have mine put together from adaptaplug stuff at Radioshack. More quality control than Asus as I haven't had this one fall and have killed two of theirs. Bought the cheap one just because.

Stop being cheap and spend money on the OEM charger. Buying third party electrical stuff with sensitive electronics isn't a good idea.
What did you save, $10-$13?

Yeah, 100% savings is bad, right?
Please, I have bought so many after market phone and tablet accessories that function just the same as the OEM overpriced name brand stamped accessories.
If anything, I think it is more of a douche move to spend 2x the money on an OEM part to get essentially the same product as those from over seas

To put the opposite spin on your story, I have purchased TONS of aftermarket no-name chargers for cell phones and other electronics, and at least 1/3rd of them were bad. I mean bad, in that they damaged the batteries of the devices they were used with.
Many of them work fine even to this day, but one bad one can turn your $10-15 in savings into a $500 loss pretty quick.
Its your device, and it is your money but keep in mind these no name unbranded chargers come with some risks.
I'm all for saving money too and I buy a lot of 3rd party accessories. But in this case though I really made a mistake of trying to save $15. You can say youre saving 100% but really that depends on the actual value. Thats like saying if you can get an OEM part for $2 but a knock off is $1 and the $1 dollar can break easily, you cant say you would still buy the $1 one. Now if you were saving $50 or more then yea that logic makes sense.
Here's another example, my friend has both iphone and an HTC phone. Instead of buying 1 charger for each she bought a 2 in 1 so she can save $. Turns out it was outputting too much amp on the micro usb side of the cable even though it says compatible. And guess what, she damaged her HTC phone. So even though she ended up saving $20 shes now out of a $500 phone. She didn't have insurance.
Anyhow after I saw what the charger did to my tablet I started googling for others and they all look identical to what I bought, so I'm assuming theyre coming from the same source in china. And the one on Amazon has the same issue. If you really still want save $ then atleast find one that doesn't look the same as the one I posted in the video.
This what I bought for your reference. 99% of the chargers sold on ebay or Amazon has the same wall plug.

This proprietary charger is really pissing me off. I too buy a lot of ebay chargers, but I typically spend the extra dollar for name brand. Not necessarily the OEM name brand but some name brand (LG, HTC, Moto, etc).
In my living room, I have a LG wall block, a 6 ft usb extension cord and a LG micro usb cord. So I unlocked the LG micro usb part and plugged in the Asus cord. Tablet wouldn't come on (yes I let it die). So I changed out LG block for the Asus block but left the 6 ft extension in. The tablet powered on but even after about 15 minutes still showed 0% battery. So I powered it off for an hour and powered it back on. It was at 5%. So I removed the extension cord which meant I had to set it down to charge (with it powered on). Within an hour or two it was at 75%.
I may at least buy a USB 3.0 extension cord do I can charge and play at the same time. Just which they'd put micro usb's in tablets like they do phones.

No charger that was included with a phone will charge the Prime. The Prime needs 15v to really charge and most cell phone charging blocks only output 5v. If you turn the Prime all the way off, it will charge very slowly but that isn't all that useful since it could take longer than 15 hours to fully charge the Prime from 0% to full using 5v source.
Also, because of the Prime's higher power requirements if you want to use a USB cable as an extension you will need to make sure that you use a USB 3 compatible cable. USB 2 isn't wired up to support higher voltage so anything plugged into the cable will only charge at 5v which is true to USB 1/2 specification.
Don't get mad at the Prime's proprietary charger, pretty much all 10" tablets have the same kind of situation including the iPad, Galaxy Tab, Xoom, etc.

Yea, I figured that out. I'm not mad, persay, at Asus as every tablet I've owned has had a proprietary charger. I'm currently the highest bidder on a OEM charger and usb cord on ebay. I've checked out the usb 3.0 cords for about $6. I may pick one of those up if I win the charger.

If you miss out on the eBay charger remember that you can pick one up from Office Depot for $30.

They're on Amazon for about that much, too. I just had to buy a new one because my original charger broke.
I am able to charge my Prime from my computer's usb port, but the dock can't be on, and it charges REALLY slow. It took about 30 hours on the computer to go from 40% to 95%.

Hi!
I noticed my phone takes a long time to charge and some times when using it while charging I will get a message about the phone being discharging as the power supplied was not enough or something along those lines.
I downloaded the battery status widget and noticed that at best, the charger goes to about 850 but for that I have to keep moving it as it seems some where inside the ac adapter and the USA adapter plug connected to it, something is going wrong.
I tried the original Sony usb cable and a different one as well.
Either way, when I move the AC Adapter parts connected to the wall, the charge changes and go crazy on the Batter Status widget , sometimes even shows like not even plugged any more :/
So I thought about trying my Transformer prime charger or I can try ordering another one that you guys may recommend.
Thanks!
Here is a pic of the specs on that adapter.
Or maybe I can use a Samsung one like this?
Samsung Charger 2A
Although the above seems to be a fake...so maybe just go with a sony one?
Sony

Looks like your Asus charger is 1.2A (1200mAh), so it's not the beefiest one out there. I'm not sure what the Sony one is, but i think it's 1.5A. Mine outputs around 800 - 1300mAh on the magnetic charger, and it uses around 2 hours to charge it from 0-100%. I usually charge it when i go to bed, but i'm always using it when it's charging in the dock, like wathcing YouTube videos and TV shows. I have never gotten a notification that says it's being discharged while i charge.
Does it get hot when it charges? (spoiler: it shouldn't do that)
I would buy a new - genuine, Sony charger. The thing is, if you buy or use a different charger and your battery goes to ****s, you can wave goodbye to your warranty. Also, since the battery isn't replacable you should treat it like your own son.
But let me summon @hamdogg for you. He knows a lot more about batteries than i do. I guess he'll show up in a minute or 12 hours. Hard to tell But he's on his way.

hahahahah, you see that Asus charger confuses me because it says but then below it also says Output 5V=2A or 15V=1.2 I dont want to fry my phone!
So you get from 800 to 1300 using the Dk30?
Also, what is the model of your Sony charger. I want to try finding one with USA plug already so maybe that Sony one is the best option for me even though I would like to start going with Magnetic charger myself OR charging an external battery (if I get one) to avoid using the USB port too much.
I got the DK30 bundled with the phone. The charger model is EP880 and it outputs 1500mAh. It only says Sony on the dock itself.

Got ya. Well I decided to get the DK30 even though now I am having second thoughts since some user seems to be having luck just using the magnetic adapters and connecting any usb cable to that adapter instead..but oh well, I guess I will get the DK30 and see how it works out for me.
Still trying to decide on that 4500mAh case/battery too!

Sorry have been away for a few days...
amps are fine no matter what the range. So 1.5 right up to 4.0 amps will not damage your device.
Volts on the other hand can damage your device. Don't go above 6v.
You should be able to get 5.v and 2.0 amps out of a wall charger, if not then its not been made properly, or not efficiently
[I have a 2.1amp unit and it suits me fine]
The difference is that your device will pull what ever I can up to a maximum, It look like the ultra can only pull 2200 (give or take) out of a charging unit, so any wall charger that states its over 2.5 amps will be a waste.
-So don't pay extra for anything above 2.2amps thinking you'll get faster charging. You wont.

I got a free 5000mhz solar charger unit sent to me to review. I'll make a video for my channel shortly about this unit. Think it retails for $15 USD. Look pretty good, just need to test it on my ultra in a few days.
The thing with battery packs, is that it needs to be 200% larger than the internal battery. So if your Ultra battery is flat, then it charges off the 5000mhz battery pack, that would mean to it wont fully charge the ultra. It will get to 2500mha, and the battery pack will get down to 2500mhz, and then it wont be able to transfer charge. (Unless you can give charge to pack)
So my solar pack can charge my device to 75%, and then continue to charge it while the solar panel charges the pack..
Does that make sense??
There we go
