Hi,
Anyone is using non ASUS Charger/Adpater using ASUS USB Cable ?. My ASUS power adapter ping came out and I am not able to use it. So I tried APPLE USB adapter using ASUS USB Cable but it does not seems to charge. Also, I tried several others and none of them seems to work either. Is there any specific in original ASUS Adapter which is required so it will not work with any other charger ?.
This is because the TF needs 11v+ to charge where regular usb charging adapters only provide 5v.
See the DIY TF101 charger and other charging methods thread for more info, there's a lot of great info in there!

5v charger will not work You need 11v on charge pin. Go to electronics store get dynex video camera charger . Use usb adapter and set voltage to 15v . Also provides an auto adapter capability.
Using a standard USB charger will work, but slowly. I have used an iPad charger and it charges about 10% per hour with the screen off. Does not indicate charging and will not charge with the screen on. Using a standard USB, same results but 3% per hour.
Either get the Dynex or a new ASUS adapter. Then you can charge around 35% per hour with the screen off, or charge with the screen on.

Technically correct, but I don't consider 3% /hr with TF off as charging.

I concur.
I was planning on using my iPad charger to charge my phone, iPad, and TF700 while on the road. It puts out more than enough current at +5 volts but doesn't work with the TF700. The Asus charger outputs +15 and +5 and works with the Asus cable and an OEM cable, and also works charging my phone using a micro-B cable. Is the TF700 charged using +15 volts?
The TF700 booklet says it can be charged from a USB port, which is +5 volts. While that may be an impossible task on a PC, it still means that the TF700 can be charged using a USB cable and +5 volt charger. Why doesn't it work? Has anyone gotten a 2A +5V OEM charger to work with the TF700? Is there a pinout diagram for the Asus cable and charger anywhere? Thanks.
Not sure if this helps, but the keyboard dock (unlike the tablet itself) can only be charged from the charger, not usb, so it must draw more power than a standard usb.
It's also possible your Apple charger usb port is pinned to only work with "apple approved" products? Have you been able to charge other devices from it?

I don't have a dock nor am I trying to charge the TF700 from a PC USB port. The Apple charger puts out +5 volts to anything plugged into to it and the TF700 apparently "knows" when the Apple charger is connected to it because it turns on if it's off.

It will charge VERY SLOWLY on 5v USB while turned off. Will not charge via 5v USB while on. The TF700 requires at least 12V/2A to charge while on. 15V/1.2A is what's recommended by Asus (based on their proprietary charger specs).
Here's a battery I use to charge my TF700 while on the go, and it also charges my phone, BT headsets and other devices. http://forum.xda-developers.com/showthread.php?t=1796750. Great battery, I highly recommend it.

You are correct. With the TF700 turned off, an hour of charging with the 2A Apple charger had increased the battery level from 29% to 34%. I expect the TF700 to be fully charged in only 14 hours!
Thanks.
Have you considered a power inverter? I use this one with my A100 though I use a FM transmitter to charge my phone.
Somewhat related to this: in the past, when using devices that have a power block with a USB port and a charge/sync cable, such as an iPod or even my Galaxy Nexus, I've used a USB extension cable to give me a little extra slack. For some reason, that doesn't seem to work with the Infinity. I've tried three different USB extension cables and the tablet never shows that it's charging. Is there a certain USB cable I can use for this?

I have that same exact charger. do you use the "I" or the "S" USB port?
I never knew what the difference between the two were
EDIT...i shouldve read the thread lol...you modified yours
I ordered a pair of cables from eBay item # 320942102464. A house charger and a car charger. I just plugged in the dock and seems to be working fine.
USB 3.0?

Are you using a USB 2.0 or 3.0 extension cable? It's my understanding that the Infinity uses USB 3.0.
You need 15v to charge the Pad (I kept thinking 11, but the adapter says 5V or 15V output). This makes sense since there are more pins. Standard USB has 5v rails (ther are 4 pins, I 5v power, Data+, Data-, ground). Since our chargers are 40 pins, my assumption is that there are more pins dedicated to charging and multiple pins dedicated to data (possibly a few that are dedicated and some that are for whatever data is being passed through (assumption)). If the adapter is outputting 11v then it can send more power through the cord and multiple pins can push electricity through. When you are only pulling 5v (i.e. most AC->USB transformers) you will need a lot more time to charge, hence the trickle effect (and don't turn on the screen!)
It can be charged with 5v if the tablet is off.
There is a jumper in the USB cable itself that kicks the Asus charger into 15v mode so it doesnt accidentally fry your devices if you plug in, say, your cell phone to charge for a bit.
To make a custom cable just throw 15v across three pins in the connector (5v each). You can find all the info here: http://forum.xda-developers.com/showthread.php?t=1633747
Yes, i know its for the prime, the connector is exactly the same, the pinouts SHOULD be identical.
DIY approach?
I've got a TF700T and a TF201 dock and a misplaced charger. I ran into the same trouble that a lot of people here did ....... generic chargers not working, USB on my computer only trickle charges the tablet, nothing for the dock, etc.......
After much poking around I learned that both require 12 volts to charge. That said I dug thru my junk and found a 2.2a 12v DC wallwart. I hacked apart a USB extension cable for it's female end, broke out my breadboard and put together a 12v USB connector... that after several days of charging and draining.... charging and draining .... works like a champ.
So to be a bit more specific, pin 1 that's normally 5+ volts I'm supplying 12+. Pin 4 is ground same as always and that's it. If you wish let me know I can probably throw up a little illustration or something.
Since I did that I've refined the whole thing a bit, cleaned it up, wired everything directly and heat shrinked the whole assembly.
It will charge both together or either one by itself in just hours EVEN while using them..... heavily. No overheating, no troubles.

I think the cable type might only matter after the ics.30 update when I was on the ics.26 I could use a standard extention cable, I had my device plugged in when I updated and my device stopped charging, and I freaked out thinking I broke something. But after finally removing the extention my tablet would charge. I have not tried to use the extention cable since so I don't know if it works with jb.

The Asus charger switches its output to 15V from 5V when a USB3 plug is detected. If you need an extesion cable to charge the Transformer, you'll have to use USB3 extension cable. If you want to use this charger on other devices, be sure to use a USB2 cable to not to fry it with 15V.

Thanks for the warning - I hope there are no cables with USB3 and micro-USB2 plugs though.
Anyone know the charger specs needed to charge this from the keyboard while docked? I have a couple and its not touching it.

the tablet requires at least 12v
Anyone know alink to a wall charger for this tablet? I went to best buy today and found they have nothing to sell me to charge my tablet. I tried my friends IPad 3 wall charger and it doesnt work. Someone suggested 12v but i cant find any of these with a volt regulation spec just wats. If anyone can suggest a wall charger and link it would be great. Thanks!

the original charger has a dual mode operation, if you stick a regular usb cable it will work as a regular usb charger - 5v @ 500-2000mah, if you stick asus transformer cable it will switch to 15v @ 1200mah
asus cable sport a usb 3 connector but uses it in an non-standard way, pin 7 is used to switch modes, if the charger find it connected it will go into 15v mode otherwise usb mode.
on the other side, the tablet wont go into "charging mode" if it dont find at least 12v on its connector so if you want to build a diy charger you'll need one that at least has these specs.

It might work but you will most likely damage your motherboard. Sucking more out than what is supplied will destroy it. Hence why FC mods are not highly recommended. Look at the specs of whichever computer you are going to plug that into. If it has sufficient power (most are standard 5v 500ma) USB ports. Just use caution. I personally just grabbed a powered USB charger. Meaning, there is a battery that can be recharged from a wall outlet, the charged battery then charges whatever i plug into the two USB ports. (up to 15volts) works great on my TF300T. However, i hardly need to use it. Battery lasts all day from a single charge overnight from the wall outlet.

Hi
I'm wandering if it's possible to mod my a510 to allow USB charging:
-according to teardown picture it's a standard 3.7V one (looks like 2 cells in parallel)
-charger is rated 12V but output is connected to extra pins- there are 2 rows of pins, one is USB and second one I guess is used by a dock
Except for making us use official charger I can't see any reason why USB charging is not present.
Do you know if it's possible to get a510/511 internal schematics?

I charge mine in our campervan off the 12V cigarette lighter plug.
The charging icon doesn't come on but it does charge, just very slowly - a few percent an hour.

This plus USB cable works.
I've also tested the standard data transfer USB cable connected to the PC.
Try it, leave it charging overnight connected to your PC.
A normal USB-cable will be enough... It'S only very slow

Until yesterday I'd have said you "no" but this night I have changed my mind.
On another forum I've read of a user that succeeded in charging the A510 via USB even if slowly (2%/hour) and if the screen is off.
I've tried many times with some 5V 1.2A USB chargers with no luck
My girlfriend yesterday gave me as a present a Anker Astro3 12000mAh battery-operated USB charger with 2.4A output and it charged my A510 from 77% to 100% in about 4-5 hours.
So, it seems it's possible to charge the A510 with USB, if you have a powerful enough charger and enough time.
I searched through some of the threads and I didn't see one directly related to my question so here it goes. I have been unable to get my tablet and or dock to charge with any other charger other then the one it came with. I'ver tried a samsun tablet charger, an 8w usb charger, other misc wall blocks etc. Will our tablet only charge with the asus charger? Any thought's or ideas on this would be great.

According to some it is possible to use a USB 5V charger to charge but you need the patience of Job and have it shut down. The simplest answer is that this tablet cannot be charged from ANY USB 5V power source.
The tablet charges at 12V 1.2A. The ASUS Charger is wired in such a way that when using the supplied cable it charges the tablet with 12V @ 1.2 A. When any other USB cable is used the charger will output 5V so that it can be used to charged other devices.
The only other source of chargers is from eBay. Just make sure you buy one that puts out 12Volts with a minimum of 1.2Amps.
There are other answers to this same question just maybe not the way you posed it!

Yes, the tablet (but not the dock) will charge from a 5V USB port, but it will be *very* slow (a few % per hour), and the tablet must be in standby or off.

Yes the original is 15V, it does actually switch to 5V if a non transformer USB device is connected. I'll add that a lot of the cheap eBay chargers output 11V to 12V which is why we have so many issues with the device trying to figure out what it is connected to.... imo.
A regular USB charger is 5V.
The tablet starts detecting a charge at 12V.
The original charger is 15V.
It CAN be charged from 5V, but you have to shut it down and it charges at 3-5% an hour. This isn't "some" mentioning it; it's in the bloody manual.
@sbdags If the cheap chargers indeed charge at between 11V and 12V, that explains the constant beeping people experience whilst using them. It keeps varying between "Charging" and "Not Charging".
So basically it sounds like the best way to charge is from the original charger/cable that came with the unit. This is no biggie. I was just trying to understand why a 8v battery back wasn't charging the tablet, but it wasn't idle, i had it on. So if I wanted to use that I would need to power off the device and it will essentially trickle charge. I don't see to many 15v usb car chargers on the market, though I haven't done extensive research. Thanks for the input.
It does charge (slowly) when on and idle - I regularly charge it overnight hooked up to my PC.
