[Q] Chargeable only through wall outlet? - Eee Pad Transformer Q&A, Help & Troubleshooting

So I finally received my ASUS EEE PAD TRANSFORMER 101!!!
Is it only able to charge through using the Wall charger adapter that came with it??
I tried plugging in the USB cable unto the computer, but it doesnt charge my tablet, only mounts the device.
I also tried using like apple wall ac adapter and...inspire 4g(phone) wall charger and non of the charged the tablet.
I usually like to have an extra stuff so I can take the extra one around places while the stock one is at home.

I read somewhere its because so the tablet would take one hour less to charge than most tablets. So it's optimized for the charger it came with.
I think you need to buy a charger with the same volt as the one it came with so it can work.

dang that sucks. ughhh. Thanks for the quick answer!
guess I should go buy a extra wall adapter.

The reason it does not charge on usb or a normal usb wall charger is cause the asus block that came with the tablet pushes 2.1 amps where a normal phone charger pushes 1 amp
it will charge off a normal charger but it wont see it and it will take about 24 to 32 hours cause it trickle charges it

[Q] Slow battery charge via usb [i9020T]

Hello, I just got my Nexus S this morning and as I am from Australia the UK wall charger that came with it is incompatible so I am charging via usb.
I did a forum search and read some threads and found out a full charge takes about 3 hours. My problem is the battery is charging only %1 every 5 minutes. At this rate it will take something like 7 hours to fully charge.
My question is: Is usb charge slower than a wall charge and would it be ok to charge my phone with a Sony Ericsson wall charger because I don't have anything else? I thought it would be alright but I am just checking because I only got the phone today and don't want to break it.

You can use any micro usb charger like your old phone or any htc charger etc. No problem. i always charge with any usb charger more than 500 mAH like 1A.
USB only has output capabiliy is 500 mA or so
charger got 800 mA or 1 A , i don't remember exact number ...
Thanks guys, I thought it would be fine but it was good to be sure.
If u want a better wall charger use a HTCs and get a thicker data cable... my phone charges fast .. the Modular AC that comes with samsungs phones suck ass lol .. and the think USB too.. buy a data cable that's thick and Ull be happy =D

I think macbooks have more juice in their USBs so I guess it depends on the computer.
But standard is 500mAh.
Ipad chargers and other tablet chargers are good for fast charging.
Are a couple of sites that sell good chronic ones.

[Q] Can we use fast charger on our HoX?

Can we use fast charger on our HoX?
Our original charger is darn too slow to charge fully our Hox so anybody tried using other charger like the charger for iphone or Nook or Smasung? Cause my nook tab
charge much faster than my Hox which also has bigger battery and my iphone also charge much quicker. Would doing such thing destroy our battery or degrade for that matter? Anyone experimented on that?
The HOX charger is 1A which is what the phone will accept. The iphone charger is also 1A.
I havnt even opened my HOX charger or cable. Just using generic 1A charger from another phone.
I've been using my Kindle charger without any problems, though I don't know what the output is.
Cant you find out what is the output of your Kindle Charger?
I have a Nook Charger here which is 1.9A and Im afraid to use it because
it might degrade my battery and since our battery is internal..it would be
difficult to have it change.
I may have found the answer here in XDA here is it
*NC=Nook Color
The answer is it depends. Here's the options:
NC, NC cable, NC charger - Life's good, 1.8A charging rate
NC, NC cable, other charger - Depends on the profile and circuitry of the charger, could be 500mA, 1.5A, or 1.8A.
NC, other cable, NC charger - You'd better use a heavier gauge wire, because even though you're not using the NC cable, USB spec says that the device may request up to 1.8A if available. NC will decide what it wants here.
NC, other cable, other charger - You'll get 500mA, 1.5A, or 1.8A, depending on the charger. Again, be careful of amperage on the cable
other device, NC cable, NC charger - *should* work, but I don't recommend it. I think ground carries a high voltage for some reason, since I've seen my USB hubs resetting and sparks coming from the connector at times
other device, NC cable, other charger - this really should work, but you're not going to get faster charge times, since again it depends on the output of the charger. I'd still be cautious since the NC cable has something wierd going on.
other device, other cable, NC charger - Go for it. I've gotten 1 hr full charge times on my phone with this method. You MUST use a heavy enough gauge USB cable.
other device, other cable, other charger - depends on device draw and charger profile mode
Yes. When I'm in a hurry I use my hp touchpad charger. It charges my phone an hour faster than the HTC one from under 10% to full.

Question about charging

Reading the manual, it says after charging the first time, that the tablet can be charged by USB if there is enough power through the USB port. I put an extension between the Asus adapter and the proprietary cord, and it won't charge unless directly connected to the adapter. I have USB 3 port on my computer that gives out higher than standard power, and I have a USB port in my car, and this tablet won't charge on anything except a direct single asus wire connection to the Asus adapter. Is this correct? It seems that I may have a defective tablet.
Are there any other people having this issue.
USB 3.0

The USB extension also needs to be USB 3.0. Is the one you're using?
The extension was to the power outlet in the wall.
I wonder if the Asus chord is made for USB 3 then?
Sent from my brain to my hand to XDA
Is your extension just a USB extension or a powered USB extension? Maybe it carries data but not power? Can you charge other devices with the extension (and do they actually charge at a decent rate)?
Yes! I charge my htc sensation on it all the time. But I more than that, I am trying to find out if others are able to charge via the Asus proprietary USB cord to another source such as a computer or car etc.....
as opposed to using the wall power adapter from Asus

I also can't get the tf700 to charge with any adapter other than the supplied charger. I've tried 500mA, 1A and 1.9A (from a Nook color) USB chargers and none work.

I am quite certain that it says in the user manual that it is possible to charge via USB, i don't have it with me at work, but can someone verify this.... it could be a major issue for some, and needs to be addressed. I know that the battery power at full charge is not going to last all day for me, and being able to charge via USB is really important since i am in sales so i do not have access to an electrical outlet, but i do have a USB port in my car.

I'll add my personal experience to this...
When I got the tablet I put in a basic USB extension cable between the tablet cable and the outlet adapter. I didn't notice for an hour or so that it wasn't saying it was "charging".
Except...in that hour the battery hadn't gone at all.
And with the screen off and left to its own devices it will charge to 100%.
So I guess the point is this, it may not say its charging but it is getting power. If you're using it as like an overnight charging thing, it should work just fine.
Doesn't the manual say that you need to power it off before changing over USB?

I'll have to check this out, but I hope one doesn't need to have to restart a tablet, just to change the power source. Kind of a pain

So maybe it is charging a little, even though it says it isn't. I think I will try this out and leave it for a few hours or overnight as a test.

So I plugged into the USB port and the power level was at 78%, I left it plugged in for about 5 hours and when i rechecked, it read 97%. The whole time it read as Not charging. This is good news, I really need that feature. It is interesting that it reads as Not charging, this must be a software error.

[Q] TF101 only charges when completely shutdown?

I am having the weirdest problem on my Asus Transformer TF101 . I had updated to ICS via ASUS's check update option and then it stopped charging at all ( I do not have the dock, just the wallwart) .... . It would not charge ( not even show a charge flash symbol on the battery ) when the tablet is on AND plugged in..It would ONLY charge with the Wallwart when the tab is completely shutdown .i.e. I would have to shutdown the tab completely and then plug it in so that it can trickle charge over night to +80%. I changed the cable , changed the wall wart same issue... Then I thought its possibly a sw issue so I resetted , wiped caches, reset battery stats and even upgraded the sw to a Rayman's CyanogenMod 10 ♦ B4 ( currently running it ) .. Now I can at least see a small charge flash symbol when the tab is plugged in but instead of charging the tab , when I look at the battery status it shows discharging.... I can only charge this dang thing when its completely shutdown.. I still think its a sw issue.. Wondering anyone else had this issue and more importantly what is the fix ?? ..
Fixes I found in the forum that I've tried so far :
1. check/uncheck the stay awake option
2. Rooted ,installed Rayman's CM10-B4 rom
3. install dual battery app to check battery stats,( dont know why was this suggested as a fix )
4. wiped battery stats in recovery mode , thrice
5. changed usb cable
6. Put the charger/wallwart in freezer overnight and then check the charging ..
I'm outta warranty duration so desperately need to fix this on my own ..
You are using the ASUS TF101 supplied charger with its included cable, and nothing else? I.e. no extension USB cord etc.
The ASUS TF101 charges using 12-15V from the wallwart, not the standard USB 5V. Using standard USB, it's only able to trickle charge during power off, and this sounds exactly as what you are describing.
I had the same problem a couple of weeks ago. I even tried the freezer trick too in desperation as it was my last resort before admitting defeat in my battle with trickle charging. In the end I purchased this charger off ebay:
http://www.ebay.co.uk/itm/140714910102?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I know it's advertised as a UK charger but if you read further down the page they ship the US and EU charger too. I've had it for about a week now and it works perfectly. I was dubious about buying a non Asus charger after reading reviews about them on Amazon about overheating but mine seems fine. If anything it's actually cooler than the original one.

I have tested with the same USB cable that came with it originally and the wall wart is original too. I changed the wall wart and USB to see if there's a difference but apparently none. Not using any USB hubs either...

Sorry to disagree, but everything you describe sounds as a charger issue to me, not a SW issue. If it happens even with the TF powered off this makes me almost sure...
Sometimes it's good to start from the begining, although you think you have tried everything...
Get your TF, your asus original wall adapter and cable and try it. Does it work?
If not try another outlet on your house. Does it work?
If not, you may even try another outlet (work, school, whatever). Does it work?
If not exchange only the wall adapter (for another asus original one if possible) and start over.
If nothing changes, get back to your wall charger, change the USB charging cable and start again.
If nothing changes, change wall adapter + cable and start again.
Remember... The TF will only charge with the asus wall adapter and cable or a specific charger. If you try to use your computer's USB or a wall adapter from a phone / generic USB device you won't get any charge at all, and will only trickle charge when the TF is off.

Sounds like there is an issue that the charger is not recognizing that an Eee Pad is attached. Might be time for a new charger.
Hello all, I have the exact same problem. I received my Asus TF101 for Christmas last year. Then later I found out that you need it root it in order to upgrade the OS. I rooted my TF, then I upgrade it the OS from Honeycomb(4.0.3) to Jellybean(4.1.2), (4.2.2) A month later after upgrading the OS my battery drain faster and I can only charge the battery with my TF turned off. If I plugged the the charger while its on it, the battery says its not charging. I change the wall wart and the cable but the issue still persist. Please help!!!

Is the new wall wart you are using a genuine Asus wall wart? If it is just a tablet USB charger, that will not work as the TF101 needs 15 VDC to charge instead of the standard 5 VDC of USB. The Asus wall wart auto-detects and switches between the two voltages to allow it to be used for other devices as well.

Charger specs

Anyone know the charger specs needed to charge this from the keyboard while docked? I have a couple and its not touching it.

the tablet requires at least 12v
Anyone know alink to a wall charger for this tablet? I went to best buy today and found they have nothing to sell me to charge my tablet. I tried my friends IPad 3 wall charger and it doesnt work. Someone suggested 12v but i cant find any of these with a volt regulation spec just wats. If anyone can suggest a wall charger and link it would be great. Thanks!

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.
