I've read about short charging cord - and the charger looks like a plug in device - that you run a USB 3.0 cable to from the Plug to your device - is that correct---- ?.
I frequently use my current e-reader sometimes while I'm charging it from an outlet at the end of the day.
* Is this possible - or does the device turn off while charging?
* Can I charge the device - while using as an e-reader
* Is there a way to charge the device while on a stand or some sort on a desktop.
I don't anticipate wanting the Dock later on - but having a way to keep teh device charged during my user habits is a must.
Thanks
You can use it while its charging.

Yeah its mains plug/charger>usb 3.0 cable>asus 40pin cable>tablet. Some usb 3.0 cables seem to work, others dont. Seems to hit and miss if you get one that works. And yes you can charge it up while you use it for anything. There should be 3rd party docks being sold in the near future if you dont want the official keyboard dock.

I was just planning on using a cheap bookstand - or building something quick and easy that I can thread the charging cable through as a desk stand / charge station.

You can use it while it's charging, but the cord being short would probably make it very uncomfortable for you to. That being said, this thing lasts all day, I don't see it a problem if you fully charge it and do a reading, it's not going to run out of juice.
Although you got me thinking about something. The connector on asus end is proprietary, but the other end is a regular usb adapter. I wonder if you could buy a USB extender and extend the cable. This would probably have to be answered by ASUS.
How about a extension cord for the power plug?

Heh thats what I've been hammering away at today. Finally made one then realised I had an old plate stand thing that works just as well. I had to use the usb 3.0 extension to make it reach up properly on my computer desk though.

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.
[Q] I have a USB charging station that has worked for every device I've thrown at it. I know the TF trickle charges on USB, but this hub is plugged directly into an outlet, and it's not charging at all. Why?
Because the TF needs a USB 3.0 lead to charge it while it is being used / screen is awake
USB 2.0 only charges when the device is powered down or in sleep mode / screen off
The usb2.0 can provide only 500mAh and as far as i know the usb3.0 provides 800mAh.
Seems to be the voltage, USB 2.0 = 5v, USB 3.0 = 12v
Just from what I have read so far, I don't have USB 3.0 so can't test

Because, as user DevCake figured out, if you look closely at the AC adapter it is dual voltage 5v & 15v. He determined (summary): if pin 7 (USB 3.0 spec) in the AC adapter is triggered by the tablet or dock then the voltage switches from 5v to 15v. Also, if you apply 11v-15v directly to the tablet or dock (via USB 2.0 power leads in the 40 pin cable) the charging indicators work. In my opinion, this triggering mechanism makes the AC adapter *more* proprietary than the ASUS 40 pin cable.
Thereafter, everyone went looking for ways to provide 15v optimally (12v also works) to charge the tablet. Over 15v is a mistake, and if you plug any of your other USB 2.0 5v devices into 12v-15v you will burn them out.
There are a bunch of DIY charging threads and comments if you look around.
Good luck.
Well, I've ordered a USB 3.0 hub from Amazon, and hopefully that works.
I know 2.0 will only give the TF a trickle charge, but it wasn't giving me anything, and the indicator was not coming on.
Anyway, I'll be sure to post the result!
Yea keep us updated, and you wouldnt see the indicator as the screen needs to be off for it to charge via USB 2.0 - so as soon as you turn the screen on, it stops charging, kinda like trying to see if the light in the fridge really turns off when you shut the door lol

You would at least think Asus would make their devices work well together! This blows; I'm sure some dev could figure out a way around this, if we knew exactly what was going on.
Read the reply from above. The tf needs 15V in order to charge. Usb was not designed with this kind of charging power in mind. Usb provides a max of 5.25 V.

I am going for a trip, and I want to reduce the number of things I carry with me, and I was wondering if I can use the Asus TF101 charger to charge other devices that plug to usb, like my mobile phone.
I know that the TF101 charger gives more power than normal chargers through the USB3 cable (Required by the device, otherwise it will not charge), but if I plug a usb2 cable and plug my phone, will it charge or fry it?
I wouldn't use the charger, I'd use a usb port on the dock, personally. I'm just paranoid though, it should be fine since the limit on 2.0 is 5v

I don't have the dock , that's why I am asking
Yes, I do that all the time to reduce the number of charging bricks I carry. If Asus only had the foresight to make it a dual port!
There is a DIY charger thread that also has lots of information about how the charger works. If I recall correctly, it puts out standard 5V normally. When the TF cable is plugged in, it actually shorts out certain pins in the USB 3.0 plug and that signals the power brick to kick up the voltage to 1.21 gigawatts that are needed to charge the TF. A standard USB 2.0 plug won't be able to short out the pins so the voltage will stay at 5V.

Be sure to thank DevCake - he did a lot of great work in this thread.
I had read that at some point, but I wasn't 100% sure as I couldn't find it. Thanks for clarifying xB
Thanks, that's exactly what I wanted.
I read the charger post long ago, but I was unable to find it today.
Just using a lower power point to charged it...
I really like my Transformer, but the lack of charging options is an issue.
I'm looking for a dual usb port wall charger (a similar car charger would be great) that will output the 15v needed by the Asus tablets. I don't mind bringing extra cords, but don't want to carry a bunch of wall warts with me when I travel and I have a lot of other USB devices. I'd prefer one without a permanent cord. Anyone found one that works?
The trickle charge options aren't effective since even overnight I only get 20% or so of charge.
What exactly are you trying to do...
The supplied charger charges both dock & Tablet where as the usb will only charge tablet..
Am I missing something?

You can safely use the Asus charger to charge all your other devices..
And if you have the tab with dock, you can hook another device to be charged up to the USB port of the dock. As long as the tab is docked and on, the dock USB will output 5V.
I believe He's asking if there are other USB chargers with more than one port that meet the TF700s power needs.

That's it exactly. Previously I was able to travel with just a single 4 port USB charger (something like the Skiva PowerFlow QuadFire) which would charge my iPad, phone, camera, and a travel router while only taking up a single wall outlet (which also means only a single plug converter for overseas). I'd love to do the same with the TF700, but would settle for a dual USB port charger (one to port charging the TF700 and one to charge my phone, simultaneously).
While I can charge my phone from the dock's USB port I don't always have the dock with me and it doesn't allow me to maximize untethered usage. Generally I use the dock as an extended battery (assuming I'm not using remote desktop or the card reader) - docking the tablet to charge it, then plugging the dock into the charger while I continue to use the undocked tablet. If the dock supplied power to the USB port without the tablet attached I'd be fine, but no such luck.
Anyway, like many, the goal with the transformer is to minimize the weight and "stuff" I have to carry (in my case a laptop). If I could reduce things further by dropping a dedicated charger for one that served many purposes at the same time it would be great. Something like the Anker Astro3 battery back up but smaller and without the battery would work well.
Maybe, try this one...you could charge your Transformer, because of the DC Output, your Notebook and of course other USB Devices...
I think he mightve wanted something like thiswww.buy.com/prod/apricorn-ausb-y-usb-power-adapter-y-cable-3-28ft/q/loc/101/202641110.html. It doesnt give any tech specs, however it states that it would increase the output power. So I would assume the volts would stay the same, but you might get more amps from usb. Unfortunately, it would just be a faster trickle charge.

Hi everyone... I have an asus tf700t and I was wondering if I can charge it using the belkin mini surge protector with usb charger ( w**.belkin.com/us/p/P-BZ103050-TVL )? I just wanna make sure if it would be ok plugging the usb cord straight to the usb socket of this belkin usb socket. I carry a lot of gadgets with me whereever I go so I kinda feel that it would be bulky carryng a lot of chargers for my cellphone, laptop... etc. Would this be safe? I just experienced last week someone's charger got toasted using a public wall socket using the original charger. Thats why I thought of buying a surge protector as well. Thank you.
Depends on what you mean. Do you mean skip the Asus wall plug and use the usb ports on this protector? Then the answer is no. The usb ports on any device you use to charge the tablet needs to be usb 3.0 and supply the needed 15v of power. All of the usb plugs that are sold are made for 2-5v devices. If there is one that does supply the 15v then I have not seen it and many people using this forum would probably love to purchase it. You've stated one main reason to buy something like this, limiting the number of plugs to carry around, but it's also like $40 bucks to buy another plug from Asus.
That 2-5v is enough to charge cell phones, gps units, apple products, other tablets that don't use a proprietary power plug, etc. It may supply a small trickle of power similar to hooking up the device to a computer while the tablet is powered off. That would take hours to charge the device and not what you are looking for. I think one of the advantages Asus went for in using usb 3.0 and 15v is the speed of which the device can charge. It is pulling more power and able to delivery it to the battery faster. That is my guess but it is limiting our after market choices.
Now if you mean use that as added protection and have the Asus plug plugged into it, then yes it will work. If you are concerned about pulling too much power through it then don't have the device hooked up to it and use all of the other ports on the protector at the same time. That little device does seem neat. I lost an a/c adapter for my laptop when lightening struck really close to my hotel. Fried the power brick but luckily the laptop was not damaged. At work and at home I use a power strip/surge protector when plugging in the tablet to charge.

Ok tnx for the input. Just wanted to be sure if it would not harm the device if I use the usb wire without the charger adapter that came with asus but rather plug the usb cable directly to the belkin usb socket. Being stated that the tf700t is usb 3 and 15v is needed, will the belkin suffice to charge the device using its usb slot for charging without causing any harm? The spec says in belkin mini surge protector is 5V/500mA each usb port.
