So would this be ok or would it damage my phone? Basically I have a usb extension with is basically a usb plug on one side and a port on the other to plug in another usb cable. I'm plugging that into the charger and then plugging in the microusb wire into that to charge. It charges fine but I'm just wondering if it's not good for the phone.
Its just extantion code where you plug in your sammy charger rite? Than you are ok no problem at all. I use this setup everyday.

Basically the bottom goes into the samsung charger and the actual microusb charger goes to the top. Its basically an extension cord for the microusb cable.
I have a 10ft USB cable plugged into my stock charger with no problem.
Not really answering my question lol. I wanna know if its safe for a usb cable to be plugged into another usb cable.
Yes it is!!!!!!

Can the transformer charge through a usb cable connected to a computer? Every time I try it won't do it (I'm plugging it into a usb 2.0). I can only charge by using the AC adapter. Anyone see this?
Only of the screen is off or the power is off, and even then it's very very very very slow.
So for all intents and purposes, no.
Why not charge it through power adapter?
For mobility, I ordered this:
charger cable extension (to make the USB charging cable longer)
USB 3.0 A male - A Female Extension Cable (10 feet)
Not really a asus accessory but for myself I ordered this mini surge protector with dual USB ports... being in south, we get a lot of lightening storms so this is a must (for bed-side and you don't want to buy huge surge protector). Plug into wall next to a PC or something:
Belkin mini surge protector dual USB charger
Hope that helps!

Let us know if that extender cable works for data and/or charging. Thanks!
it charges in 1 of 2 ways
USB [email protected]=10watts
Wall [email protected]=18watts
so, as you can see, the wall is the much more effective choice.

I have one of those Belkin units, they're very nice. But I can't find the specs showing the output on the USB ports. Is 15V @ 1.2amps a standard and this supports it? A bit ignorant about such things...

Charging through USB 3.0 from expansion card?
Has anyone try charging TF (& Dock) through USB 3.0 available from expansion card?
I have and it doesn't work but several people have tried and it does. Seems to be hit and miss as to whether it works or not. Even same usb 3 cables have different results.

There could be many things at fault here. First would be the usb 3 port and whether its on the mobo or card, and then i would put fault on the drivers (or not having installed them)
Why don't people want to use the charger that came with the unit? I can't imaging not using a unit with a least the same output (V & A) as the factory unit. Also, does anyone know if the pinouts track with what is coming out of a USB 2.0. It would not be too good to put power into the wrong pins.

No I mean to say that some people, including me, are trying to extend the charging cable by inserting a usb 3 extension cable between the mains charger and the tf.
It works for some, not for others
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.
Sent from my Desire HD using XDA Premium App
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
When I got my Asus TF700T I got one power plug and 2 USB to tablet/dock plugs. The first thing I was VERY disappointed about is how short the USB cord was. When in my bed I could not plug it in I had to use it off battery only due to the shortness of the USB cable.
I went out and bought a USB male to USB female cord to use as an extension cord and low and behold it would not charge both the dock and the tablet when plugged into the Asus supplied AC adapter. I am assuming the extra length might have knocked down the power from the AC adapter just enough to not charge both devices.
What you need -
1) Original USB to Tablet Asus TF700T cord
2) Any length Male to female extension cable. I bought a 7 foot.
3) A 110-220 to 12 volt 2 amp power jack(car jack) converter. This is the one I bought any should work with the same specs. http://www.ebay.com/itm/130962356608?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
This is a very easy "hardware hack" to do.
1) Pull off the 12 volt car jack at the end of the converter it will leave you with a + and a - cable coming from the power brick.
2) Simply strip off the male side of the USB extension cable disregard the 2 data cables and just use the + and - power cables. Solder/clamp/or connect and cover each connection with electrical tape.
3) Plug the USB cable into the female end of the extension cable that is connected now to the converter.
3) Plug in your dock and tablet and watch both charge at a decent rate. This gave me enough cable length to plug it in behind my bed and be able to have it plugged in and on my lap.
Also doing it this way allows you to not have to hack up your devices USB cable and you can still take it out of the female end for any syncing or traveling purposes.
Hopefully this helps someone else who has issues with how short the charge cable is for this tablet.
A USB extension cable does work, but you specifically need a USB 3.0 cable. 2.0 doesn't allow enough voltage to travel through.
All I did was buy a lamp extension cord for .99, plug the wall wart into it and plug it in the wall. Now it's close enough to the bed or anywhere else I might be.

Or you could do that. :laugh:
Still the best solution, I quite agree.

...because the charger uses some of the USB 3 wires to detect the tablet and enable 15 V - with a USB 2 cable it detects only a generic USB device and charges it with the standard 5 V.

I have a USB cable like this where the power strands were split into two to provide more power. This cable was originally from an external USB DVD burner, where the one female end plugs into the burner, and the two male ends plug into the PC.
I was wondering if I could use this same cable to be able to use a Quick Charge 2.0 wall wart while still be able to transfer files from the pc. Basically the female end will plug into the phone, the male data+power end will plug into the pc, and the male power only will plug into the wall wart. My end goal is to only have one cable on my desk to plug into my phone, and not have to go under my desk to switch back and forth between plugging the other end into the PC or plugging it into the wall wart for charging.
I was wondering if someone tried this before and if it does indeed work. Or if it will cause problems, like if the power current from the wall wart would flow into the PC and short something. Any ideas?
Thanks
