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.

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.

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).

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.

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.
Hi just wanted to check if its safe to charge my flyer with a usb connected to a wall socket.
When I bought my HTC desire s I got one usb cable along with a wall unit. So I use the cable to charge + sync.
I travel a lot n it would be convinient to carry one wall socket and 2 cables one for desire s n one for flyer.
But is it safe to charge the flyer from a usb which connects to the wall unit ...since they gave a seperate wall charger in the box.
Please help
Its very safe, but most likely the charging will be much slower especially if the Flyer is on. I would recommend you power down the Flyer when charging but this method. The special charger that comes with the Flyer provides a higher voltage and current than a standard USB charger and cable so it charges faster.

Yeah you can...if the Desire is mini-USB then you could even just carry the one cable too - a normal mini-USB cable will fit in the Flyer socket (sort of upside down to how you would expect it to fit).
But the difference is 9v/1.67a Vs 5v/1a (or even 0.8a depending on the USB charger you are using) so charging would be a lot slower. On the road, if you only have one charger then you can't charge your phone and tab at the same time...if you're like me and don't like leaving stuff out in a hotel room when you leave for dinner, then you might find that it is so slow you can't get phone and flyer charged overnight!
If you travel by car, you can get 5v/2a chargers, and even twin 5v/4a chargers (2a per socket) which would turbo your charging - but I don't know what circuit protection HTC uses and I guess there is always a chance of goosing your battery...
Technically charging with lower current is better for battery, it more " deep" and " real"
But you have to wait up to 12 hours to make it full charge *_*. if you keep the screen on and charge with 5v 1A, the battery still drop *_*
9*1.67 ~ 3 * (5*1) . it mean it only take around 3+ hours if you using wallcharger, same as normal handphone.
So it just up to you But sure that it safe.

You mean Micro USB. Mini USB will not fit the Flyer (nor the Desire, I believe.).
Thank you guys ...yes the charging on the usb is very slow. Takes lot of time.
Like when I land I would go for dinner to aocal pub n would want it to have enough charge to catch a movie before I wind down ...usb wouldn't be the best choice.
I guess ill have to carry 2 chargers. Hopefully one day I find a 9 v wall unit to make life comfortable.
Right now I'm using a wall unit that came with my dv cam which is 5v.
Anybody tried to use standart HTC 5V wall charger for Flyer?
I have HD2 and its charger can safely give 1A. This type of chargers have USB data pins shortened. So all HTC devices conneced by standart USB cable identifies it as AC charger. I have tried to connect Flyer for a half a minute. Charger was identified as AC and as I remeber (not shure...and afraid to test once more) Flyer was sucking more than 1A (Battery monitor pro).
Flyer AC charger is 9V 1.62A, standart charger 5V 1A so question is do Flyer detects difference between Flyer charger and Standart 5V charger? Is it safe and possible to use standart 5V charger?
yes you can use standard USB, it will just charge slower

Have you tried or you just think so?
If flyer tries to get more than 1A, yes it will charge slower, but it will also burn charger.
I charge with reg usb all the time
Sent from my PG86100 using XDA App
I do it routinely. The device cannot draw more than the usb port will supply. PC ports supply only 0.5 amp. So they will only work if you turn the power off the Flyer. Wall chargers vary, some supply 1 amp. The original is 9v 1.6 amp were usb chargers typically are 5v so they will charge slower, much slower in some cases.

Sorry for last several anoying questions. Just want to be shure.
1. Do you use HTC charger or other vendor? In most cases only HTC 5V chargers are identified as 1A AC chargers. If not - device will not request more tha 500ma in order not to burn USB port (device thinks that it is port in that case)
2. Did you see that Flyer identified charger as AC source?
3. Did you charge when battery was less than 10%, what was charge current value on Flyer
Ok, now its getting annoying, did you actually read the information I put in the post you quoted? You just ask me the same questions I already answered.
The chargers all run on AC and produce DC . Flyer original output is 9 Vdc 1.6 amp .

Sorry but I think you did not gave the anwer. My english is not so good so maybe the question was not clear. I will try to explain once more, it is up to you to answer or just end this conversation/thread if you think i asked same stupid question once more.
1. Usually non HTC 5V chargers on HTC devices are identified as USB port and thats why devices draws no more than 500mA. It made so no to burn USB port.
2. All 5V HTC chargers on HTC devices are identified as AC 1A, so devices try to get as much as thay can (usually phones request less than 1A).
3. HTC Flyer with empty battery can request no more than 9*1.6A=14.4W. Flyer charger can handle that. Standart can handle only 5*1A=5W.
The question was: do 5V 1A HTC charger will not burn because Flyer identifies charger as AC and can request more than 1A. USB ports usually have protection from current. I do not know if 5V HTC chargers has protection or do Flyer identifies difference between 9v and 5v chargers and sets max current it can get from charger?
extra pins not present on a usb cable for mains charging. if using usb cables the the flyer is a usb device and has the same power restrictions as any other device...simple as that.

You are not right.
HTC 5V HTC mains charger comes with standart USB cable with no extra pins. Thats true. But mains charger has Data+and Data- shortened inside what makes HTC phones think that it is mains... with any USB cable. So power restrictions will not be as for USB....but as for AC. I have tested that in practice. I made belkin car charger and iphone charger able to be treated as mains chargers just by connecting pins (iphone charger data pins should be disconnected from schema before connecting. I have secret how to connect pins without opening unopenable iPhone charger....).
So the question is Flyer is able to identify mains 5V1A and 9V1.6A difference and do it apply different restrictions. Now for both shows it as AC source and I think sucks as much amps as it can up to 1.6A. So teoretically it should burn 5V charger if it will suck more than 1A.
What are you trying to do exactly?
---------- Post added at 06:29 PM ---------- Previous post was at 06:28 PM ----------
by the way, it is standard, not standart.
I use the Flyer with a variety of USB wall chargers, car chargers and PC ports and have never experienced fire or explosion, only charging and slow charging. Are you trying to figure out how to use a different charger and still get a rapid charge rate?
Ok, I think I understand what the question really is but it is poorly phrased.
On my previous statement I agree with your answer in terms of how it is possible to read what I had said, in fact probably the logical way to read it on re-reading what I wrote, what I meant was electrically present, not that there were extra physical pins, whether electrically present is hi or lo doesn't matter.
If the question is can you rapid charge at 5V from a sufficiently powerful 5v then the answer is no, even if you pull D+ and D- to ground. Also it is highly likely that in the AC charger a resistor rather than direct connection is used to pull them to ground and these resistors could be electrically significant in the overall charging circuit.
The most probable reason for this is that there are two parallel charging circuits in the flyer ( almost certain of this ), and hence why 9v is used. The charge voltage for a 3.7v battery is 4.2 volts and somewhere around 500-750mA, the second charging circuit will have an isolation circuit to ensure that it is only engaged for charging purposes and does not directly feed the tablet that would be the purpose of the modified connections of d+ and d-, activate the secondary charging circuit.
Assuming you feed the device 5v from usb that would mean that the second circuit would receive a 0.8v supply, probably (hopefully) not enough to activate it so you just burn up the extra as heat in the circuit. In theory you would see a higher current draw by asking the flyer to run as if it was connected to an 9v supply when you connect a 5v supply. Best and most likely case scenario you're just being inefficient, medium case you burn out a component or protection (eg thermal fuse), worst case scenario you reverse the battery and it gets damaged or explodes.

This is what i meant! I was curious which one of scenarious will happen in practice.
From DigitalMD post above I can make a conclusion that in reality we will have 1st scenario (just inefficient).
Thank you guys.
I recommend you look at the following USB battery charging spec. A properly designed charging circuit will have current limiting and can recognize the power capabilities of the port vs. device vs. cable. This is why some charging circuits use a special cable vs. a standard USB data cable.
http://www.usb.org/developers/devclass_docs/Battery_Charging_V1_2.zip
Nice link, it's got some pretty decent information in it.
Honestly to answer your previous question I can't tell, I'm guessing nothing except some heat, but that doesn't mean that you couldn't thermally damage something ( eg the screen ).

I think that there is no chance to damage Flyer thermally But theoretically, if Flyer wll requests more than 1A charger can overheet and possibly damage the Flyer. But if Flyer can detect that charger as 5V1A and if it can request less than 1A, then it is safe. Also if charger can detect current higher than 1A and can limit it - that also should be safe to use it.
I will read pdf maybe there will be some good info.
I use a self powered usb hub as a daily charger for both my Flyer and Kindle. Works fine. With no "burning out". At work, I use a generic 5v 1a charger, no problems either except for charge speed...
The charge state shows USB instead of AC, so it appears there is some sort of voltage/amp sensing going on?

Your flyer identifies charger and hub as USB and limits current to 500ma. The initial discussion was about the case when 5V1A charger is identified as AC. This case happens when standart htc phone charger is used (eg HD2 charger). That charger has data pins shortened inside that makes HTC phones (conected by standart USB cable) think that charger is AC. Surprisingly Flyer identifies it also as AC. In that case flyer do not limit current and possibly tries to draw 15W from 5V charger which can deliver only 5W ! I think that good chargers should have protection from oveload....
So soldering data pins together in you generic charger would make it more efficient. I modified my all generic chargers even genuine iphone charger and now all HTC and possibly other phones identify them as AC !! But I still not shure is that safe for flyer.
Little bit offtopic:
Yesterday i dissasembled Griffin car charger thas has 2x1A USB ports. In fact there is a chip inside that can deliver up to 3A. The chip is XL1583E1. This chip can be set to deliver other voltage than 5V by changing resistor.
It would be nice to get somewhere flyer pinouts and see if it uses the same pins for 5V and 9V charging. If the same - it means that this car charger can charge flyer as fast as flyer mains charger just coupling data pins (now it has identifications circuitry for iphone -resistors between vcc,data,data,vdd). If not - it means that charger shoud be modified to deliver 9V and special cable with extra pins will be needed also.
you sure are going through a lot of contortions just to do same things that the HTC charger that comes in the box already does. Why not use the adapter made for the device?
Can anybody recommend an external power pack that works with the flyer/view? I was looking at this:
http://www.amazon.com/New-Trent-IMP...FO/ref=sr_1_20?ie=UTF8&qid=1324398340&sr=8-20
It will work with your Flyer, but it will charge much slower than the HTC power cord due to the USB connector. It may or may not keep your unit powered during normal use depending the way you use your device since the current supplied will be limited by the standard USB cable (~500ma) vs. the propriety HTC charging cable (1200 ma). I would test by powering your Flyer off a standard PC USB port and see, This should be roughly equal to what this device will supply.
Hmm, me thinks I just spotted hardware hack number 3.

This would be great please keep us updated
I picked up a Dreamgear iSound 8000 ma model on sale from expansys, seemed like a nice unit and was supposed to be able to push 2amp but it's no faster with the HTC cable than a regular generic microUSB cable hooked up to a usb port. The biggest drawback was the thing completely died on me before the first cycle, I mean DEAD, won't charge and the flashlight doesn't even work. So much for on sale, return shipping $$.

As I posted previously in this thread it does not matter what current the source supply can provide. The cable is the magic. Standard cable, standard charge rate of 500ma which is about 30% of what the HTC charger will give you
DigitalMD, reread his post. He clearly states that using both the HTC flyer cable, as well as a standard micro USB, gives him no difference. So while your conjecture that "it does not matter what current the source supply can provide. The cable is the magic." is interesting, it is not, in fact, entirely accurate. Perhaps the cable is "the magic" in certain environments, but clearly not all.
No conjecture at all, in this case it is a fact. The Flyer cable has extra pins and conductors that are not in a standard USB cable. This tells the Flyer when a power supply is connected vs. a standard USB and the Flyer then allows for higher charging rate. Whit out that special cable, it will only charge at 500ma or aprox. 30% of the HTC power supply rate.
Actually less than that even. The htc charger runs at ~9v > 1amp. A lithium battery can rapid charge in the range of 900mA to 1.2A depending on the cell(s) in the battery.
There are two cells or two packs (can't tell which on visual inspection) in the flyer battery running in parallel. A proper htc charger running at 1A provides approximately 10W of charging power, a 5 volt source running at 500mA provides 2.5W so the USB charging will be 4 times slower.
As discussed in another thread shorting USB D+ and D- will allow the flyer to recognise a wall charger and charge at 5v 900 mA, the same could be applied to a battery pack capable of providing 900 mA sustained. It wouldn't be as quick as the wall charger but it is probably enough to provide for charging while using the device, rather than just slowing discharge.
On the question of leads, using a htc cable or standard micro USB makes no difference by default. When connected to a USB socket the flyer/view cable behaves like any other USB cable, the wiring modification is done inside the charger for a wall charger, and would most safely be done the same way for a battery pack.
The flyer internally uses a threshold voltage plus the D+ and D- pins to determine if it is charging from 5v or the dedicated higher voltage wall charger.
yes your post is a more accurate explanation, thanks
Thanks for the input. I will give that one a try and take my View cable with me. I have long road trip coming up.
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.

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!

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.

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.

Yes I already know this. I can always return the charger if it does not work properly. Also last night, I tested an OEM HTC charger that came with my older HTC Desire Z and it outputs exactly as the OEM Samsung Note charger. I used your command line in Terminal Emulator.
Got it today. Wow it charges fast.

OK I was wrong it does not charge faster. It actually allowed my battery to drain at about 1% per 4 minutes, during driving. I DID NOT USE PORT 1A. Will try 1A tomorrow.

What did you get? The motorola one or the Blackberry? Link please.
Thanks for this. Will be ordering the PowerGen. Just got back from a trip to Chicago from Ohio and left with 100% and arrived with 70%. Figured the charger just wasnt putting out enough power.
Now I just need a good adjustable windshield mount that will accept my phone with a case on it!

I just got this one: http://www.amazon.com/Satechi-Lighter-Converter-BlackBerry-Playbook/dp/B004X71HXU
It comes with a adapter that shorts the pins to enable rapid charge.

Even with GPS running my battery is fully charged when driving to work. I ordered a couple extra adapters from the Satechi website to throw in my laptop bag to rapid charge over the USB 3.0 port and one for my wife's car. Now she can rapid charge her captivate with the high current car charger finally.
Sent magically through the air from the mighty Note!
