NO battery, Wi-Fi connection needs power that a battery cannot supply [not for long any how ...]

Yes, you can charge the battery with the USB cable that goes to computer and it also comes with an external wall charger. Also a second battery was included so you will always have a spare!

No, but a USB cable is included which can be connected to a computer/laptop to recharge the battery.

Is the power adapter necessary for this drive or will it run off he computer battery if needed?

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.

You just plug it into the electrical outlet & the other end into the computer. If you are not moving the laptop keep it plugged in...Wont hurt...

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

No; with the battery charged you are completely portable. You must connect to the computer to 'download' the scanned codes from the device. You will also plug it in to charge it. But other than that you are portable.

It isn't an external battery. You put the battery in the laptop and connect the laptop power cable.

Not necessary. It has an "Auto-off" feature, so you can leave it plugged in.

It needs a 120V outlet and has no replaceable battery. See my review for limitations of this computer.

It needs to be always connected. It runs on USB so you might be able to use one of those backup batteries with it

Hello Susan. No, it isn't it needs to be connected to power. It's very nice but I don't consider it portable.

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.
