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.
Hi.
I'm looking for an advise about car charger that can charge my TF700.
does anyone confirmed that there any car charger that works?
I mean, I saw some posts that says that ASUS' charger is 15v instead of the more common 5v?
but then I saw the charger, it says " Output : 5v === 2A or 15v === 1.2A"
So I assume I can use other car charger that works with other tablets?
can someone confirm this for me?
THANKS
The tablet will only start to detect a charge at 12V.
Charging at anything lower than that will charge about 1-3% every hour.

oh. okay. any recommendation on what charger should i get?
preferably one with dual USB.
USB is not going to work, in any form or capacity. a USB port can only put out 5V at max.
I use a power inverter that puts out 230V (bought it for my laptop a couple of years ago) through a normal outlet. Plugged the charger into that and it charges normally. You could try looking into that.

YES the ASUS Transformer will only charge from between 12 & 15V. They DO NOT charge from 5V USB.
I have found that the car chargers which have the ASUS 40 pin plug attached to the cable work fine. They have a regulator circuit which outputs 12V at 1.5A minimum.
The ones available on eBay work well and aren't too expensive. They are a little bulky because of the high current circuitry so look at the pictures and make sure that it looks bigger than the average ones and you will do fine.
unfortunately there's no car charger available as of yet.

An Carcharger is avilable, i have one and it is working. 15v 1,2A Carcharger with normal Asus connetor. I'm usin it since 2 Month, never had problems. Carcharger is even cooler as the 230V USB charger while charging. Asus Tabel also switch immediately in charging mode. 14€ at Amazon.de.
By the way, why is everyone saying 5V won't work? On my 230V USB charger there's following note "15V 1,2A or 5V 2A"
Well won't need it, just buy this one ( which i have):
www.Amazon.de/gp/product/B007PQ8AN6/ref=oh_details_o04_s00_i01
Just ignore that tf700t isn't written there and that the charger would have 1,5A. Thats wrong, Carcharger has 15V 1,2A.
If you won't believe me, i can make an picture ( that it will have 15V 1,2A and works) otherwise have fun with it

Why aren't you reading everything? I said 5V charges too slowly for the tablet to detect, but it does charge. About 1-3% an hour, which is useless when you're using it. It clearly says, in the manual, that it will only charge over USB (5V) when turned OFF and not connected to the dock. RTFM.

I don't know how many different threads I have to post this in...
http://www.amazon.com/gp/product/B0081BFYY2/ref=wms_ohs_product
Includes a home charger, car charger, and an extra USB cable, that ALL work. I have been using these with my Transformer Prime, and now my Infinity without an issue at all, and they provide the ASUS required specs for charging and work just like the factory provided chargers.
I ran into this issue with my Verizon Samsung Galaxy Nexus. When attached to a charger, if I went into Settings...Battery... it would show the status of the charging process: it would say "USB" when connected to a computer, and charged at a much slower rate, or "AC" when plugged into the supplied charger in a regular outlet, and charged much more quickly.
With most car chargers, it would only show "USB" but there are some car chargers that have the correct wiring so that it was recognized as "AC" and charged as quickly as when plugged into a regular outlet.
I have two of these in my vehicles, and I just checked one of them, the one listed below first, and with the Tablet plugged into it, it shows as charging, as an "AC" source, just as with my Galaxy Nexus.
Here is the one I specifically tested and verified that it works:
Dual USB Car Charger
I do note the 2 negative reviews there, but all I can say is that I've had this one for almost a year, and it has worked perfectly for me with my phone. A brief test with the Asus Tablet confirmed it was seen as an "AC" charger.
This is the other one I have and which works fine with my phone, although I have not specifically tested it with the Tablet (I have no reason to expect it would behave any differently):
HTC T-Mobile myTouch 3G Car Charger
Obviously, I can't be held responsible if somebody else has a different experience with these, or has problems because of it. Just trying to be helpful and report what has worked for me.
You might consider the i-Blason 12V 2A MINI BULLET STYLE CAR CHARGER FOR ASUS Eee TRANSFORMER from Amazon (Sorry, but noobs can post links)
It's compact, uses your existing cable and delivers 12 VDC @ 2 A. Under $10 US.

It may work, or it may not. Drawing on my experience with the Galaxy Nexus, there were quite a few car chargers that had specs like this but which in fact were seen as "USB" chargers when used with the Nexus, and I suspect would behave the same way with the TF700T.
I am not an eletrical engineer, but it has something to do with how certain pins are shorted or not, and not all chargers that say they deliver the higher amperage will in fact do so with all devices.
It'll just take somebody to buy and try, and report what does or doesn't work. Per my post above, the chargers that work with my Nexus also work with my Tablet, in being seen as "AC" charging.

Don
I have one on order and will pick it up at my daughter's when we go to the US next month. Will post what I learn.
HOWEVER - a true "USB Charger" provides a 5VDC output, not 12- 15 VDC, as does the i-Blason unit I mentioned. Note that i-Blason states very clearly, "Warning: Pls do not use with other MP3 or smartphone... High Voltage could cause burn out."
The difference many smartphones (and other USB ported devices) detect in "USB Chargers" versus "AC Chargers" is max current available (<0.5 A vs >1.0 A) For example, I have a USB battery and a video cam that will both fail to illuminate the charging light if connected to a charging source below about 0.75 A, but still charge, albeit slowly. Both came with 1.5 A USB (5 VDC) wall chargers.
Since the i-Blason is a 12 VDC, not a 5 VDC output, the odds are high it will charge the Transformers at a rate very similar to the wall charger. At least based on electrical "theory". If I had to blind pick a third party car charger, the specs for the i-Blason, to include using the stock cable, were what influenced my choice.

Hi
Im searching for a car charger for the nexus 4 that will charge the device even on navigation running...I now that the Motorola Rapid car charger was good with the galaxy nexus.I dont know if itS ok with the nexus 4 because on the LG charger it sayS 1.2A?I read that the Bracketron Universal Dual USB Car Adapte 2.1A will just work as AC charger if plugged in with a USB charging only cable...but i cant find those cable to order online here i Canada...and i dont wanna do it myself and modify a regular usb cable ...Soo if someone can help me it would be much appreciated.

You dont have to have a modded cable if your car charger already has the data pins shorted. Im using the motorola rapid charger too and it works fine, it will charge your phone as AC and give enough power to recharge the battery with navigation on. if you want something a bit better you can try this one , they ship to canada. My rapid charger broke so i bought it a few days ago. Reviews says the trident will give around 8-900mA, the moto charger outputs around 6-700mA.
I would only buy a premium brand here. If you see how no name mains adaptors are made... the risk of blowing up something expensive is just too big.
I wnent with the Sony AN-400 / 401, because it is rated at 1.2 amps exactly, is small, and was reported to work fine.
For some regulator disasters:
http://hackaday.com/2012/08/15/buying-cheaper-electronics-and-not-saving-money/ <- a USB car charger without components, putting 12 volts straight on USB.
http://www.youtube.com/watch?v=wi-b9k-0KfE <- teardown of imitation apple mains adapter, showing no output protection and very little gap between mains voltage and output circuit. Good info, but style of presentation is not my cup of tea.
So that is why I went with a premium brand.
that's one charger from one factory that some guy that didnt know what he was doing and ordered thousands, without testing them. He probably went for the 25 cent super deluxe model...
Well reviewed chargers from xda members here and not to mention the hundreds of people on amazon are a safe bet. Here's a 8+page thread on the charger i linked. Your premium brand name sony charger is made in china too.

If you're into rooting and custom kernels, most of them have a fastcharge option where you don't need to have a special usb cable, or, attempt to short the D- and D+ lines.
Monoprice has a 2.1A bullet charger for a bit cheaper:

i cant say for sure until i get it sometime next week but i think so. im in canada too and couldnt find the powergen anywhere that would ship here.
There are some other brands that are good too but i like this one cause it's dual usb like my old moto rapid charger. If you dont need that you can get some smaller ones that will work just make sure they are well review and can output around 1A. The one that bfspider spider recommends is a good bet too since monoprice is pretty reputable store and will ship to canada.

You can try to mod this one in the mean time, just take it apart and attach the two data pins(they are the two middle ones). Solder is best but if you cant you can just use pilers and bend the pins until they touch. i did this with a few of my chargers too and it works to make them AC but it wont increase the output if its low to begin with.

FYI, this adapter should allow most existing "iPad" chargers (1.2A or higher) + any USB cable to work well with the Nexus 4.
The problem is that Apple products deviate from USB charging standards. As a result, most chargers try to be compatible with iDevices and also deviate from the standards. So when standard-compliant devices try to follow the standards, the chargers refuse to follow the standards, and the devices get upset with each other. Fortunately, they fall back and settle on a lower-power charging rate.
If you want to buy chargers that are very clear on what they support, check out MediaBridge (also available on Amazon).

So i got that Trident charger that you recommended....the quality looks good...but when I tried it in the 1A and 2A port with the usb cable that comes with it,it shows USB charging but when I use the HTC usb cable that came with my HTC one S it shows AC charging....its so confusing and I just dont get it....that HTC cable is a sync and charge cable.
The generic T-Mobile car charger available at T-Mobile stores charges just fine. I believe it is at least 1 amp. Its black, has a purple white small led indicator when charging. The USB end looks like a little block and the cord is an accordion type and it also has a a female USB slot in it to plug something else in at the same time but I believe whatever USB cord you plug in there only charges at .5 amp. With this charger I can run navigation and Bluetooth and Pandora and message at the same time and it will charge.
Sent from my often RMA'd Nexus 4, So that I can use the one I'm using now when I get the 6th and hopefully final one.
I just dont get it why does it with one cable show USB charging and with the other HTC cable AC charging?:S

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.

just buy an asus transformer compatible charger on amazon...
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.
