FYI for hardware modders...
The dock connector looked familiar. Plugged in the cable for my sandisk sansa 280. It mates perfectly...
Any potential uses? The other end is USB...is there a pinout for the dock?

I wanted to bump this, since I just realized it myself after looking at the PDMI schematic on wikipedia. I didn't plug it in to my PC for fear of altered power pinouts, but has anyone else noticed this? My cable is from a sansa e260v2
I was wondering if this would allow USB charging for the the tab. It does charge through the dock.

It would be cool if this works since you can pick up sansa 280 cords and also car charger cords on amazon for only a few bucks. That would be nice if it works with gtab, making this great for on the go and usb charging with the pc.
you will never charge it with usb....without step up voltage and amps not possible.

It is not a secret, that charging over data cable is slower, rather than over electrical plug. I think it is due to USB max current is 500mAh, while my direct charger output in 1000 mAh.
I wondering if the same is relevant to car chargers. I'm having the one of so-called USB Car Chargers, which has the USB plug as output, than you connect it to your phone thru the data cable.
If I buy a usual mini-usb car charger, would I get any benefits in charging speed?
Thanks.
usb max current is 500ma on the spec, you can draw much more than that over the copper.. as long as it's not being regulated by "compliant" circuitry/drivers, you should be able to draw 1000ma
Ive been looking into this tonight, and I checked my GF's iPhone wall charger (which is basically a wall USB charger) and it outputs 1000ma as well, and ive found a few usb car chargers putting out 700, 800, and even over 1000ma... only problem i have is i need it to be compact... i currently have a 500ma one in the car but that didnt seem to really charge the phone...

The reason I am asking is similar:
When I am driving with gps and 3G turned on my phone is never fully charged. In fact, it seems it even uncharging a bit. I am wondering if the same happening with usual mini-usb car charger.
And if I want to buy new on ebay, they never specify the mAh parameter.
I bought a 1000mAh USB car charger for a couple bucks at monoprice.com.

same here... when i have the turn by turn going on full brightness and such it does uncharge a bit over time... but look on the bright side, its not getting raped as much as it would be if it were just using the battery

Hmmm... they don't seem to have it on their site anymore, which is odd cuz I ordered it only a month ago. Here's the info off my e-invoice:
Product ID-3523, Car Charger (Cigarette Lighter) to USB Female Converter - Black $1.16
You might want to email them and ask when they'll have them back in stock.
you can find them on ebay

me too....this charger is awesome
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
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.

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

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'm using the stock charger but the cable is a bit short for me. I have two 3' USB extension cables but neither of them allow the tab to charge. The tab lights up as though I plugged the charger in but it doesn't ding nor does it actually charge. That are standard extensions and work with my Kindle & various HTC cell phones but not my TF300T. Anyone know why or could someone suggest a brand/type of USB extension cable that would work? I am also comfortable with buying a new one and rewiring or swapping wires on it if need be or buying wire and 2 ends and soldering it myself.
Since the tab is 15v and USB is 5v I'm guessing they swapped a wire somewhere in the plug to allow for more voltage.
Thoughts?

You have to use a USB 3.0 extension cable.
Seriously? That's it? Man, I feel like a dummy. It never would have occurred to me that 3.0 was necessary. Thank you for the help!

Yep that is it.
I bought my USB 3.0 extension cable from www.caseen.com. They also carry the stock chargers, cables and a couple other items that I was unaware even existed (a 2 port USB hub that plugs into the USB on your TF300T dock WITH an Ethernet port so you can connect DIRECTLY instead of staying wireless!). Fairly decent pricing and fast shipping.
