Yes, gets powered by the USB port. Yes and I have used a 12 Volt car adapter with multiple 5V outputs or any other 5 Volt usb adapter does the trick. No need to use the provided charger

Yes. It automatically turns on once plugged in, but can be shut off while charging.

Yes, the USB port is the ONLY way to charge it. Any external source 5V (the 1A determines the speed of charge, could be less but will take more time) is ok as long as the connector be a Mini-B USB connector.

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).

Same way you charge your phone at home. It comes with a cord, there is a spot on the charger to plug it in for the charging purpose. All you need is a USB wall port and you are good to go. We just use the same port that came with our phones.

It is supposed to be plugged into the same place as the charger. If you have an Acer or Asus tablet, however, nothing will make it work. It is, essentially, a case of false advertising.

It most likely will charge your tablet though, depending on the current output of your computer's USB port, it may take somewhat longer than plugging it in to an AC adapter with a USB connection. The voltage output of USB ports is fairly uniform at about 5v so it should not harm the tablet by doing so.

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.

The USB port is powered by plugging into a wall outlet. It then charges your devices (phones, tablets, etc.) through the USB port into a cord into your device. I am not sure if I understand your question completely, but you can not supply power back through the USB when it it is not plugged into a wall outlet (I don't know why you would want to do that. What would you be sending the power over the USB to? A power outlet??? Also, there is only one USB outlet on the device so you can not charge from say a laptop to a phone. And again why would you, just hook the USB cord from the laptop directly to the phone in that case.)

This charger comes with a short cable to charge it. Its a usb cable on one side and a micro sd cable tip on the other side. So if u need to charge it, yoy can plug it into a wall phone charger or your computer. Or really anything that has a usb port

I just plug the charging cord directly into my regular USB hub. seems to charge fine. It takes a while to fully charge the first time.

It charges via micro USB cable (included). So you can charge it via your laptop, desktop computer, or USB chargers like the one included in your iPad/ iPhone, etc.

It does not have to be charged. Simply plug it into the tablet and, voila, it works just fine.

You charge this charger by plugging it into your computer or the wall. It has a larger USB outlet. It's not the micro like you would find on a regular android smart phone. The cable that I used to charge it came from an older phone I used to have. To charge your phone or tablet with this, you plug the larger, flat side of the USB port (the side that normally goes into a computer) into the other side of this charger (you cant see it from this pocture) and then the other side of that cord into your phone. Hope that helps!

You charge it with the included micro USB cable. Charges fast. Works well. You can use just about any micro USB charging source.

You can charge it with either of the provided cords. The smaller end of the cord goes in the actual external battery and the bigger end goes in the wall charger outlet like any other normal USB charger would go into. Hope I helped!

The way it comes out of the box you halve to charge with the USB. You can buy a charging adapter from Amazon. I had a suitable charger that has the same wattage, so I didn't buy one. Either way of charging works great.

Can your tablet charge off a USB port? If you check the "output" on the charging cable that came with your tablet, does it say 5V and 2.1A or less? I'm not sure the exact model of your tablet, but you may actually need the EasyAcc 15,000 mAh battery, which has a port for charging 12V tablets.

I'd like to clarify that the USB port is for charging another device, not for charging the battery. In other words, it has a USB port like you would find on your computer for plugging something else in to charge. You can not power this charger via USB, only by plugging it into a wall outlet.
