Can this be used without a computer? Meaning, does it need a power supply or can it run on battery power?

This doesn't use an external power supply or battery. It simply uses one USB cable that splits into 2. Plugging the tablet into to USB ports powers the tablet and runs the display, digitizer, and express keys.

NO. It is powered via the USB on the PC, and acts as a monitor (via usb). It requires 2 USB ports.

No, it will need to get power from USB cable. Meanwhile, it will also need to get signal and drawing through computer's support.

My unit is a plug in, does not run on batteries. The description of portable may be that the unit is lightweight therefore can be used anywhere a plug is available.

You don't need to. For the starter kit purpose there is a USB cable that will power the board from your computer when connected. However if you want to run the board and not have it connected to your computer than you will need a power supply.

It does have a battery, which provides more flexibility in use, but it cannot work independently of a computer.

It comes with a its own power supply that must be plugged in. While it would be possible to power it from batteries I don't think it would be practical, it would drain them pretty quickly.

Well everything electronic runs on electricity, but I think you are asking whether or not it is portable. The answer to that question is yes, and it is battery powered

No external power supply is needed. It is "plug & play". It gets power from the computer's ExpressCard/34 slot.

Yes it can be charged without a computer. It can be charged with a usb type charger that plugs into a standard 120 volt AC outlet with 5 volt, 1 amp output to the usb port.

Yes. It has a battery and I have used it both ways which is the reason I bought it. If I need to use it without electricity I can just as well.

There is no battery needed. Alternatively, if you wanted to use a battery pack you probably can, but again, not needed. It comes with a Mini USB Male to Common (A-Type) USB Male Cable. Ive powered this from a laptop and had no issues. I also plugged it into an extra USB Adapter from an old phone and worked great.

It can run attached to a power source but only with battery in. Thus you slowly destroy the battery's capacity to hold a charge. If you can remember to turn it off when not using, then battery will last. Don't buy it if you have a choice. I have three so far -- they only keep working about 6 months.

You can buy a power supply to eliminate the need for batteries. Check the instructions or go to google for more information.

It does not have a battery if that's what your asking. It needs to be constantly powered through USB and needs to be connected to a device that can use its drivers, otherwise it wont work.
