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.

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.

It uses a cigarette lighter cord for operating power. It plugs into a PC using a micro USB cable for updating the software -- no additional power source required for that.

It hardly uses electric power, I absolutely love this product and recently gave one to a friend.

The battery is a backup in case of power interruption. From a practical viewpoint you need a low voltage power supply.

There are 2 power sources. You can either plug in to USB or the wall for it to work.

There is no power source. It uses the pressure of the water supply. I followed the hookup directions that came with the pump, and it works great. Instead of the drip, drip, drip, the pump goes "ffftt, ffftt" occasionally.

Just a 110 plug in. I have run mine for over a year and I don't really notice an increase in power useage.

it runs on 12v, so any 12v source will work. I'm using a battery pack for a project with a switch on the positive side.

You can use either power supply ac/or dc with this product, because it comes with an adapter to do both. I guess if you needed it on your boat or camper you could do so with no problem.

Comes with its own power supply. It has a 110 AC household plug. The cord is a little short but I had no problems making it work.
