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

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 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?

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.

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.
