Has anybody noticed that you cannot charge the tablet through the microusb port? I use this tablet at work in my car and I cannot get my existing charger to do anything so i took the tablet inside and plugged it to the computer for conformation and it doesn't charge there either. So I guess I'm gonna have to find a DC charger for this. Anybody know where I can get one cheap?
The Acer doesn't use a proprietary connection to charge so you should be able to find a generic charger that fits with the same barrel connector 12Vdc 1.5A (1500mA) - another plus over the Asus
Check your local Radio Shack store for a universal charger that matches. Heck, Wal-Mart might even have it, Best Buy probably will as well.
This question about charging over the USB comes up a lot - but that'll probably never happen with 10" tablets. The screens are so big, that makes the batteries need a lot more power, and USB just isn't designed to produce the kind of amperage required to charge it.
I just bit the bullet and bought a good inverter.

This is what I have currently. http://goo.gl/WKniM
Black and Decker has a new model now that looks different http://goo.gl/2LV4X but it's worked out very nicely for me. I swear by it. It's saved my phone so many times as well as my previous tablet.
I went by reputation to get it as it shuts off before it causes your vehicle's battery to die (if your battery is weak). Many of the others will drain it until your vehicle can't start.

How do u connect the inverter to the tablet, what cable do you use or does it come with a suitable plug?

Hello,
Just got my EEE Pad with the keyboard dock today.
I read that for the first time you should charge the batteries for at least 8 hours.
Now, what is best? Charging the tablet docked or to separately charge the tablet and then the dock?
Thanks
I use the keyboard dock as a charging station to be sure both batteries are fully charged. The other reality is that power is power and I doubt there is any real difference except for the convenience and amount of time involved.
Bye.
Yeah in the end I decided to dock the tablet and charge it through there, seeing as I am working until 7, I wont be able to play with it
Hey everyone,
Before my Transformer arrived at my door-step...I started reading around a bit more about spare chargers and such - and came across a few threads that people had had trouble charging their TF101 because the AC Adaptor was fried/dead/whatever.
I own the B60 version and all seemed to be going well until late today. I plugged in my charger as per usual...and no charging icon. I did a few plug ins/outs and swapping the polarity of the plug to no avail. I also tried an iPad 10W charger and that did nothing; proving to me that only the supplied charger or a 12V molex rail can charge the thing.
I then thought of any changes I had done to my TF101 over the course of the last 24 hours. I remembered. I had installed Clemsyn's kernel v9 on the Revolver 2.5 ROM. So...I thought about reverting to Netformer 1.6 kernel I was using before.
After flashing, it started to charge again. (Note: I did reboot the TF101 a few times before this to see if it was a Honeycomb issue).
This is a theory anyway....if the chargers are failing on stock ROMs and kernels...well that's ASUS' fault.
Hoped I helped anyone.
i don't know about this. I got a b60 also. The charger didn't work the first night I got the transformer. Stock rrom stock everything. I played around with the charger and it worked again. Now sometimes it works, sometimes it doesn't. Im on custom rom now and its still the same.

I was completely stock when my charger just stopped charging both the dock and the tablet. A few days later it started charging only the tablet and only doing that occasionally. It never did charge the dock again. It was the impetus I needed to finally RMA everything back to Asus for which I am waiting its return. It seems to me that this charger just can not be trusted and that is a big problem with a proprietary charger!

How many chargers have you owned, and how many of them have died? If it's a sample size of one, it's pretty-much meaningless. You only hear complaints from people who have a problem, after all.
Personally, I've used three chargers (mine, my wife's, my fathers) with three tablets and three docks, and none have had problems as yet (several months).
I have a B4O TF (fantastic BTW) and my charger died ...stock rom etc.
sent to asus...week later they still can't find my RMA (and I thought Dells customer service was bad)
I had already bought a charger for spare so I can wait
I bought a 5mm DC Female Barrel to USB Female cable - EBAY $2.99 and I'm always looking at chargers for it when I see one... Bought a I home 120V AC to 15VDC adapter at goodwill this weekend for 1.99 total cost of my new charger (others gonna stay in the drawer) 5 bucks and some change
find the Barrel to usb connector link and info about it in DevCake's thread here

i had the same problem with my charger month back when i got my pad. i called asus. it is a known problem. they sent me a new /replcemnt part for the charger. no hassles . ive been fine since
I experienced this same thing last night. I had flashed to Clemsyn's kernel Elite v12a kernel. I did a reboot however and charging resumed. I was having a hard time connecting to the computer as well. Perhaps, the kernel or settings still thought that the Transformer was connected to a PC because it will not charge from a PC unless the screen is off. There must be some script that is being interfered with here. Your theory may have some traction.
I was rooted when mine decided it didn't want to charge anymore, I had only had it for 5 weeks. I unrooted and even back to stock it still didn't want to charge. I sent it back to them and they fixed it after a week. Everything's been good so far.
My charger was working intermittently and I was near the point of returning the TF w/ dock or buying another charger. Then I tried running the charger thru a car power converter in my car and it seems that did the trick. Now it charges everytime, its worth the try.

okay so im not the only person here. my charger just stop charging yesterder. never rooted, always stock rom. i did factory reset, and still no good. now it only charges very slow, no charging icon showed. the cable is good, i can still connect to laptop.
The real question is: Is it the pad or the adapter? Because if it's the pad, that sucks big-time, if it's the adapter it is irritating but not a real problem, you could charge it via USB on your laptop/PC
I finally contacted Asus regarding to the faulty charger. And they told me to return the whole thing to the my retailer, because im still within the 30 day return period.

Charging via a PC is very limited. It will be very slow if it works at all. The charger provides higher voltage (15 vs 5) and higher current (1.2 vs. 0.5 amps). The charger and pad also expect the current on non standard pins association with USB 3 connectors.

Gotta be the adapter. I tried everything to get it working again, I noticed that when the screen was off, and I plugged it in, nothing would happen. But If I plugged it in to a smaller charge adapter, it would show the screen (as if something were connected), but not charge. So I tried my friends charger and it instantly started charging. However, After I charged it, I went back to my old charger, and it worked again. WEIRD! I have a backup adapter now just in case it happens again. Same thing happen in the past, It wouldnt charge (and I didnt have my friends), so I let it die, and charged it with my smaller adapter (which took like 1-2 hours to get 7%). Then I plugged it in again to my old adapter, and it charged it. It's almost like the charger reads it as full, and wont allow it to charge anymore. Then when some other adapter start charging, then it realizes it does need battery. No idea. Just my 2 cents.
Clemson Blades v.17 fixed it for me
Charging required a reboot after a certain amount of uptime. But, I also use Battery Monitor Widget's circle battery status icon. What was wierd is that sometimes the ASUS battery icon wouldn't show charging, but the circle battery status icon would.
Anyway, everything works for me now with Clemson Blades v.17. He specifically added in usb forced charging with v.17.
I saw the same problem with both ac adapter and computer's usb, but it was fine for a while after reboot but would stop working again after a while.

If anyone did a search, you would know that this is a common problem.
The trick is to unplug it for 5 or so minutes and it'll work again. Also, the writing on the plug should be facing up.
can i use any charger that can fit into my kindlle fire?
i have a charger of LG optimus one and it fits exactly.
i cant find shops selling kindle fire charger here in the philippines.
the original has 1.8A - would try to get one that has around this value
with a charger under 1A i'm pretty shure you'll get charging problems or at least it lasts very long
basically you can use every usb charger ...
Yes you can as long as a charger has equivalent current as the original charger.

I lost mine and just been using the iphone wall charger with the mini usb cable and it's been working fine. Does charge pretty slow but that's all i can do for now.
Any USB charger will work, but one with less current won't charge as fast.

No... I got a charger off ebay and it said it was for the Kindle Fire, but it was only 1000 ma. and I had all kind of problems, There are several threads on this already..Get one at least 1.8 amps and you'll be ok..
The Kindle Fire will recharge from a powered USB hub or computer just fine, and that's only 500 mA. The USB spec doesn't allow for anything greater, so you may run into incompatibilities with other chargers since compatibility is the main reason we have specs. Hopefully manufacturers are talking to each other about how to make fast chargers, but, given Houndog101's experience, it doesn't seem like that's always the case.
The Kindle has a 16.3 W*h battery, so you can calculate how long it'll take to charge given any current (5V * current = Watts), if you account for the loss due to the Kindle being on at the time. A standard USB port is going to take at least 7 hours to fully recharge the Kindle, and probably more like 10+ if WiFi is on. So I'd definitely go for a 1.8 A charger, and hope for the best. Don't spend too much since it might not work unless it's specifically made for the Kindle.
Belkin F8Z630 charger
I've bought several of the Belkin F8Z630 chargers and been very pleased with them. Not cheap, but they deliver a solid 2.1 A at 5 Vdc, they can handle any input 100-240 Vac (basically worldwide usage), and they have a nice rotating plug feature that is handy in some tight spots. Works great for charging the KF quickly.
I found one in my car from an LG that chargers it just fine, and in a timely manner.
What happened to the stock charger? The one that cane with my fire did not work at all

I don't know if this is "common knowledge" or not, but apparently the USB port on the keyboard dock is a Sleep/Charge port! I plugged in my HTC Rezound to the port & it started charging just like it was attached to my PC. The tablet was docked and turned off. I read about one person who had a Prime that could charge only if the tablet was docked & I read another person say they couldn't charge anything at all.
I don't know if the TF300 is different in that regard, I only checked charging with the tablet plugged in. I'll test charging with the tablet out this afternoon. My assumption is that it won't work. I figure the ports on the dock aren't active until tablet connection is made.
UPDATE: I tried to charge my phone with just the keyboard dock (no tablet inserted) and it didn't work. So apparently the tablet must be docked for the USB port to become active.
Nice. Pretty cool hidden feature for anyone with a dock. I wonder how much the tablets battery drains though charging a phone. Probably also extends the life while tethering.
