Is charging the pen through other usb port (ex. usb ac adapter from cell phones) a bad idea?

Yes, bad idea. We do not recommend this. Please charge the pen through nomal USB port on computer.

I just checked the instructions that came with the unit. It states that you can charge USB devices on AC or battery power but in order to save battery life the unit will cease charging external devices if being played on a high volume setting during battery operation. Hope that helps. ;)

I charge mine from either the car adapter or a wall wart in the office. Use a quality one, like an iPhone USB charger. No issues with mine.

You can only charge the device via use, so if you have cable that from one side will get the usb of the device (female usb) and from the other side you can plug it to the wall - problem solved

I've charged the battery from an electrical outlet with a USB adaptor and that works. I haven't tried charging it from the USB port of another device.

If you have a usb style electrical (ie. wall socket plug that you can plug a usb cable into), plug, yes. I use my cellphone charger to charge it up when I need to charge via wall instead of my computer.

Hi!! Don't worry about that. You can use a standard micro USB cable for charging, like normal smartphones. Thank you for considering. Sincerely,

The NotePal can take a mini or a micro USB connection for power. So if you have a USB wall adapter, like for a mobile phone, then in theory you should be able to use AC power with the device. It does come with a Micro USB cord, though it is very short. But it does not come with a wall adapter, so you'll have to find one to use with it.

Personally , I wouldn't recommend doing that .Follow the manufacturers manual on charging methods and you should get good service from the unit .

I charge it through my computer using the USB hook up but it also takes the same charger insert as my Samsung Galaxy cell phone so you can charge it that way too.

I have charged it from several different usb ports. So to answer the question yes.

That is an interesting proposal of using a charged battery in the charger to try to charge another device using the attached USB port. I have never tried it. Reviewing the manual, it only talks about using the USB port as a power source from computer to charge the battery in the charger but not the other way round. Do not know the answer. You may call Anker yourself. 1 800 988 7973

Yes, you shouldn't have any problems charging any of those with the 2.1 amp port. You need to use the 2.1 amp port to charge tablets or else it will take a looong time to charge.

Easier still (and you'll have it for other things) get a DC to 110 volt AC converter, plug it into your car power outlet (we used to call them cigarette lighters) and plug in the charger that came with the tablet (then there won't be any question as to whether another "car charger" will work - or cause damage).

I'm sure you can. I use it for all sorts of different devices. I have noticed that it may take longer to charge certain items than their own plugs may but I haven't found anything that didn't charge at all.

No, that would be a function of the unit being charged, but I'm not sure there is a danger of overcharging with phones, etc. This unit is not as strong and , therefore, as fast as your regular USB cable from a wall plug.

You can charge it via computer, A/C, or your car. You can find an accessories 3 piece kit sold on here that includes all 3, although the computer charger is not necessary as it's included. It doesn't have that nice mini-USB port like most gadgets, but the other, wider type of port that many old cell phones have. I think it's a peripheral port, or something to that effect.
