Does anyone know how to enable "rapid charging" on CM10. You know, where you trick your phone unto thinking it's connect to a AC adapter when it's really connect to a USB cable? The reason I need to know is it charges relatively slow on the car charger even though it gives off just as much amps as an AC adapter.

I think it has to be supported by the kernel.
You can always buy a charge only usb cable or make your own if you own a spare cable. Obviously data will no longer work over this cable but it will charge on AC mode no matter what it is connected to.

I have just bought up my transformer ( Love it ) but it's at about 10% battery right now... I take the cable that came with it (the usb one) and plugged it into my computer but it is not charging ? Any idea what's wrong with it ? when i plug it into the charging unit it works fine though
i've heard it has to be turned off for the USB charging to work....
Like off as in screen off or off as in complete off ?
It will not charge in your computer. You have to charge it in the wall.

One of the pamphlets that came with it said the screen has to be off in order to charge it using a computer's USB port, cause the screen uses too much power and a USB port doesn't output as much, its best just to charge with the ac adapter. Nothing is wrong with your unit, thats just how it works.

Turn off the screen and it will charge. (you don't need to turn it off; you just need a black screen) It is very, very slow though.
My wall charger never charged my tablet so I am awaiting a replacement. The USB charge is MUCH slower than the wall charge. We are talking about maybe 4-5% an hour -- max with the USB cable alone.
Connecting this thing to a computer will NOT charge it. Even a normal 5V 1.2A-2A charger won't charge it fast enough. I used a 2A charger and it trickle-charged for over half a day and managed to clock in @ 50pc. I think the unit uses hardware info from the ASUS charger to detect the charger. Any other charger wont do.
Isn't the cable and charger USB 3 and charging is at non USB 2 values (voltage and current).
Good amount of mis-info in this thread...
The unit *will* charge from computer USB, assuming the USB port provides enough amperage (not voltage). I have not yet measured out the amps used, but it's on my list of things to do...
In order to charge from computer USB, the display on the Transformer needs to be off. The unit can be on, but it must be asleep.
The adapter that comes with the transformer provides 15VDC via extra pins which loosely resemble USB 3.0. These are *not* USB 3.0 data/power specs, however a USB 3.0 extension cord could be used to lengthen the existing adapter.
Any USB car adapter should work to charge this in sleep mode, similar to a computer USB port. In order to "fast charge" in a car, however, you'd basically need to use an AC inverter with an ASUS Transformer adapter.

Tried a 2.1A 5V charger. Took about 8 hours to charge @ 50pc. The ASUS charger is rated at 1.2A.
is the only way to plug the device into your PC or laptop via USB on the dock?
you cant use the proprietary charger cable to do USB data transfer with the charging cable USB component?
ie....to do data transfers via USB (not the memory card), the only way is via the dock?

No, one end of the charging cable is regular USB and the other end (tablet-end) is proprietary. You can transfer files over by connecting to your computer's USB.
awesome, thanks.
do you think that if you get a male/female USB converter, you could plug in a USB memory stick device or a mini hard drive device and have it work fine in the charging cable just like you would if you were to plug in a mini hard drive into one of the usb ports on the dock?
As the cable is too short, I attached an extension cable.
However, now it does not charge. If i connect the short cable that came with the Transformer, it charges fine. Any suggestion?
The TF101 "short cable" as you call it, is a USB3 cable, what has +5 pins inside. One of these pins control the 15V charging (the tablet takes 15V from the charger instead of the usual 5V USB), if it can not send the signal through, it won't charge. You need a USB3 extension cable what's pretty expensive though.
Get this one or a similar one. As you can see, 2 reviewers vouch that this cable works.

I can vouch for it, too.
Got on of this USB 3 cable while at HK and work without any problem.
Thank you guys. Will be purchasing one. I am guessing Belkin F7C008QAF Conserve Valet USB Charging Station - Energy Saving wont be working with this :/
That is correct, because the transformer looks for termination of one of the usb 3 pins, if you plug it into a usb 2.0 or lower extension/hub it just wont work. You must have a usb 3 extension/hub, or, there are many DIY chargers that are probably cheaper than a usb 3 extension cable and definately cheaper than a usb 3 hub.
Even a usb 3.0 hub or charging station will not charge it. Usb does not provide the voltage required. Only the outlet adapter will work

Are you saying that my cigarette outlet will be the only thing that charges this?
It won't charge it all with anything unless turned off. Guess I need to make a hybrid cable
Posted on the fly with my XPLOD Evo4G
My charger that came with the SGS4G is not an official Samsung one. This is because I bought my phone used and it came with a 3rd party charger.
The charger is just a one-piece charger. I cannot remove the cable. It says:
AC Charger
Model: Micro USB
INPUT: AC 90V-240V
OUTPUT: DC 4V-8V
Can I use this charger with other phones that charge over MicroUSB? Do I need to make sure the other phone can handle 4V-8V?
Also I intend to buy another charger as backup, but I have this adapter which I plug in my USB cable into and then it goes to the power outlet. When I used this, my phone acted very erratic, swipes would not register correctly, phone became unstable, etc. Any reason for why this would happen?
It's sounds like your generic USB charger, and should charge anything that would charge if you were to plug it into a computer's usb port. I have a belkin usb plug, except it has a usb port on it instead of a cable, and it charges everything, even PS3 controllers lol.
Who makes this charger? If it's a super cheapo, the power may be dirty and may cause your phone to act funny.

It is some cheap USB to AC charger I got from Dealextreme. Never had a problem with my old Huawei U8100 or DSLite.

Yes and yes to the first two questions but it normally isn't a problem depending on what is charging.
To the third, I had that same problem with my ZuneHD and a generic manufacturer's cable and I still don't know why.
Sent from my SGH-T959V using XDA App
The major issue is "are the data lines shorted together?". If they are not, your phone (and other devices that use USB for power) will see it as a simple USB port and limit draw to what a PC USB port can supply (not much).
There are also some ways (particular resistors used across... pins 1 and 3?) to indicate how high the charger can go.
Most of the USB car chargers (at least the ones with USB ports) do NOT do this, so they take forever to charge a phone.
Easiest way to tell: with the charger charging, go into device settings. If it says "Charging(AC)" you're good; "Charging(USB)" not so good.
Do the TF200/Prime/Other cables word with the Infinity?
I'm thinking about just getting a couple of spare cables here: http://www.amazon.com/gp/product/B007GJR7GS/ref=ox_sc_act_title_1?ie=UTF8&smid=A1HKVQTYI2W24Y but want to make sure that they fit and work.
Also, (perhaps a separate thread?) Can we use any AC to USB converter (and cable) to charge the Infinity? The adapter bundled with mine was a bit more robust than normal adapters so I'm inclined to think no, but wanted to confirm before I get a spare one.
My cable from my prime works with the infinity....I also tried a cigarette to USB plug in my Jeep and it would not charge the Infinity
if anyone finds out if other USB charging adapters work successfully, could you please post about it?
much thanks

None of them will work. The charging cable for the TF700 doesn't use any the USB pins for charging. It has additional USB3-style pins hidden up inside the connector. Also, the stock charger outputs 15V which I doubt we'd find on any standard USB charger.

Actually, correcting my previous post, it can charge via a USB 2.0 connection (as on a standard USB charger) but very very slowly. The current is not enough to charge it while the screen is on. The display will read, "Not Charging" but it actually does. See the following thread for more info:

Umm... did you actually test that? I went through my charger pin by pin with a multi-meter and found 5 VDC between pins 1 and 4. Look closely at the charger, it says it can supply 5VDC @ 2A or 15VDC @ 1.2 A. The only reason for switching to 15VDC would be if they had some sort of feedback signal on pins 2 and 3 going to the plug-in adapter to signal that the battery was fully charged and tell it to switch to a higher voltage/lower current mode.
ASUS standard charging cable has 5 pins instead of 4. I'm betting the feedback you're looking for actually occurs on the 5th pin.
I wonder if it's possible to charge other devices by connecting them to otg cable and charging them by phone battery power.
Actually i want to know the max amperage which the usb connector on the phone can give?Can i connect my mw600 bluetooth headset to the phone and charge it(i usually carry my otg cable and phone charger in my bag)?I can test it but i don't want to do anything rash and damage my devices.
thanks
I guess it would be 500ma as like on the PC.
