What is its power source while in use? Does it have to be directly connected to the wall socket, or does it need to be connected to a computer?

It has wall socket and believe will scan without computer and then when you plug in will load images at that time

It has a USB cord which can either be plugged into a computer/laptop or it also has an adapter that the USB plug can plug into which connects to a wall plug. So either a computer or a standard wall outlet.

It is powered by the USB connection and doesn't require an additional power supply. It is not wireless and must be connected with the USB cable.

It needs to be plugged in. It's portable and can be moved around the house, but it needs power.

it must be plugged into a wall socket. Or if you have a power inverter you could use a 12vt outlet. It does not have a battery in it.

It uses wall current and can use batteries. Wall current should be your primary source as batteries don't last very long in this device.

Yes, it plugs into a standard wall outlet. It also has a cord to connect it to your computer, but I have not used it.

No batteries on mine. No power cord, either. It connects to the computer with the USB and that's how it gets its power.

It needs to be plugged into the wall socket at all times. No battery operated function.

It plugs directly into an outlet. Beware these units are highly unreliable, read my review for my results. They are cheaply built and have a high failure rate.

It's not a portable power source. It has to be plugged into the wall. If u need portable power get the anker. I bought like 4. They wrk great

I'm not sure I understand your question. It is an electronic device so it needs a power source. The battery is built-in, and can be recharged through a USB port on a computer or laptop.

No power source is required.use the included usb cable to connect the hard drive to the computer.

It's powered from the computer's usb port. It has two usb cord connections, one of which must be plugged into a powered usb port on your computer. Check that your computer has at bleast one powered usb port. Most likely it has several.

it plugs into the power supply directly. Then plug into the wall or surge protector of your choice.
