If my memory is good, a 9 volt batterie or ac adapter. Gave it as a gift and got a bigger one for me.

Powered by USB, whether off laptop, desktop, or direct plug with a USB port. I love it!

it requires a DC power source. If you want to use AC power you will have to convert it to DC.

there is no power source. This is a vise that can hold your work or it has an adaptor that it hold your Dremel tool, which is a good feature. It is not heavy duty, it is for light work. I use it to hold circuit boards and small light items. I like the adjustable positions and the size of the opening of the jaws.

No, there is not an external power source included, it only comes with a USB cable. However, you can connect this USB cable to one USB power supply that can be connected to your +12VDC car adapter, they are very popular now.

Both: primary power is from the outlet, but there is a back-up wafer battery, a 2026, I think.

It uses a small, onboard battery for its power source. I believe it's a AAA battery - should say in the description.

The power supply is an option. It uses a 9 volt battery (not supplied - no surprise there). When the power supply is used, the battery functions as a back-up.

The other answers are correct. This needs to be plugged in to a power source.

Sorry, don't understand this question. Extra power supply to what? My review was about the battery charger and it doesn't come with a power supply. You provide the power supply by plugging it in to an electrical outlet.

Power source only. You use a wired connection to set it up, then it is wireless.

Power source is a USB that only works if you are on the computer, the earplug port is an odd size and hard to replace and kind of high, The recording for the voice is not very good on playback. It worked for 3 weeks of listening and stopped, I gave a second one to my nine year old since it did not work well. hope this helps!

It's powered by the USB cable it comes with. I'm happy with this hard drive. It has an extra usb power cable if main usb output is not giving it enough power

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.

The only power source I found on the one I bought (and subsequently returned) was AA batteries. I could never get mine to work, so it went back to the provider.

Yes . . . otherwise it will be sourcing power from your PC, and it is designed to you it's own power source.
