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:

I want to extend the charging cable. Can I use any regular USB M to F cable or do I need something specific?

you need a usb 3.0 extension cord to extend the cable

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.

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
Sorry if this has already been asked and answered - the XDA Search has been down for the past couple of hours and I just want to be sure I'm not missing anything here..
From what I can see in the reviews, the TF does *not* have any sort of charging indicator / LED on it - correct? I read that there will be one on the keyboard dock - but there is not one on the tablet.
So what are you guys doing? Just plugging it in and letting it sit overnight to give it its full charge - and then going by the battery indicator when you turn it on?
I've got my new TF sitting next to me here, and I'm trying to be a good dad to it by charging it up first before using it - but not having any sort of an indicator on it - I have no idea if it's doing anything or not!!!
Screw it - I think I"m gonna unplug it and start futzing it with it! Battery be damned!!
btw - damn this charge cable is SHORT!!
No charging LED that I can see on mine, and yea, I hate this stupid charging cable, guess you can always get a USB extension cable.

Monoprice has the USB 3.0 extension cables, but they won't be in stock until tomorrow (their estimate). When they are back in stock, a 6ft extension will run you about $7-$8 shipped.
I plan to order a few cables from Monoprice with a mini hdmi to hdmi cable.
Does it need to be usb 3.0 or will usb 2.0 do the trick ?

USB 2 cables don't supply enough power.
It will charge, but I think it has to be off and it'd be really slow going.
But usb 2.0 extension cable will work fine with the supplied charger? Also would you not require a usb 2.0 to usb 3.0 converter ?
Asus really overlook the inclusion of an charging indicator. Or, they are trying to make more $$$ on the keyboard/dock?

Has anyone got some definitve experience on USB2 vs USB3 for charging and/or with an extension cable. The whole charging process and adaptor are making me a little nervous in general.
there is no reason to invest in USB 3 gear when all you really need is higher amperage, wich you often get from stand-alone chargers like the one supplied or you can buy in stores (just check that the output is 1000mah or more, 2000 mah is desired for effective charging).
The reason you might want to use a usb 3 PORT (cable makes no diffrence) is that usb 3 deliver more juice then usb 2, but unless it is a dedicated charger port that can supply 2000mah+ charge the port still require you to have the pad either off or stand by and even then charging will take ages.
Consider this, the supplied charger delivers 2000mah on 5v and my HTC charger to my phone has 1000mah @ 5v. Compared to the standard 550mah on a singel non-charger adapted USB port on a computer.
The TF charger output at 15V @ 1.2A with using the supplied USB3.0 cable. If you use a USB2.0 extension cable, it will drop the charging voltage down to 5V. You will need a USB3.0 extension cable

There's a thread about this issue here. Several USB 3.0 cables have been found to work, but not for everyone. I have this one that I received today. It charged both the tab and the dock with the wall charger. I've also got a Tripp Lite that's worked for others on the way in the case the other didn't work.
it has to be USB 3.0 extension since the tablet recognizes the extra pin which is what lets it charge at the full rate.

Not quite correct. The charger senses a gnd connection on pin 7 of the USB 3.0 connector and delivers 15V @2a to the TF and or Dock. There are only 4 conductors in a USB 2.0 Cable. so the charger only delivers 5V as it does not see the gnd on pin 7. For all the technical details see the thread started by DevCake where the voltages and currents have actually been measured. A 5V 20A charger will not be as good as one with 11-15V at about 2A as the charger is not a constant current charger but a power source for a charge controller ( controlling the current) in the TF.
I appreciate that it is a slightly older thread and not sure if what I'm about to post is already known by TF owners but here goes anyway.
The discussion has moved on to cables but the threqad title is about a charging indicator. I've discovered that the battery icon in the bottom RH corner has a lightning symbol through it when it is being charged.
Sorry if it's old news but I've only had my TF one week and thought other users might not be aware
Really wish they would have put in a fancy multicolor LED somewhere on the housing but we can't win them all. Even the Nook Color had an LED on the cable itself.
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
Even after cruising through some searches, I'm still trying to nail down the specifics of the cable and charger. The charger says it runs at 2A at 5v or 1.2A at 15v. Does anyone know why it has two listed and which mode it actually uses when plugged in?
Also, I'm interested in 'extending' the 5 foot charging cable and have seen it suggested to use a USB 3.0 extension cable. Can anyone confirm that this will work okay?
Lastly, I'm looking at the Antec UA4-25 charger to sorta consolidate my charging needs. Anyone have any feedback on this and whether it will work okay with the TF700 and/or a USB 3.0 extension like I mentioned above?
Thanks for any feedback!!

The charger can actually output both voltages. The 5V is used to charge regular USB devices. When you plug a Transformer, one of the USB3 cable pins is used for identification of the tablet. The charger then switches to 15V voltage. See this and this threads.
Any USB3 extension cable should be OK to use. I haven't tried that myself, but I'm sure it would work.
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.
