How long does it take to charge?

[carnifern]

So I got my transformer with about a 50% charge. I used it for an hour or so and then let it charge fully. Then I intentionally ran it down to 0 in order to give it a full charge. Problem is that it's still at only 15% after about 3 hours. At this rate it's going to take 12+ hours to fully charge. My stock charger was defective but I luckily have a backup which works. I do have it turned off and plugged in to a wall socket. IS there something wrong? Thanks.

I have never actually timed it but I don't think it took more than 3-4 hours to charge from almost dead. Of course I didn't sit and watch and wait either.

I'm at 32% right now. Gonna stick it on charge and see how long it takes.

Ok just a follow-up. Took 1hr 45min to charge from 32% to 100%. At that rate it should charge form dead to 100% in about 2hr 15min.

Are you convinced that the backup charger works??

Mine recharges from 10% to 100% in about 2 hours.

Yeah, it`s the 3rd party adapter i used when I used an iPhone and it always worked fine. Could it be the battery in the tablet itself that`s the problem?

I read a thread a couple of weeks ago where the charger requirements for the Transformer were covered in some detail. My recollection is that Asus specifies a 15V charger for the Transformer but chargers as low as 11 volts may work. I suspect that an iphone charger does not come close to that. Most phone chargers that I have seen are 5 volts.

You might check the output of your 3rd party charger and see if it comes close to 11 volts. If not the charger could be your problem.

The user manual recommends using only the included charger. Looks like the cable taps 12v off the USB connection as well. Make sure you leave the screen off. It's the display that consumes the most power.

Apparently my 3rd party charger is a 5V DC charger from DLO so thanks for the heads up there. So it sounds like the problem itself is a bad charger from Asus so I'll likely have to get a replacement. The giveaway is that the Transformer turns on when I plug it in with the 3rd pary charger and does nothing with the stock one. I tried bending the contacts out a little as well but nothing. Thanks for the help.

Is there any indictor light on the TF101 when charging without the dock?
