It comes with it's own power supply and plug. This item does not use batteries.

Yes it takes batteries. Not sure which kind right now ... I think AAA's. No power cords and it has a hanging bracket on top. Works Great!

I have mainly used mine with the power cord and the batteries inside. I would think that it would work with the cord only.

It does not run on batteries it gets it's power from the docking station that it is plugged in to.

It doesn't have a battery and it runs on car charger. So it works as long as it's connected.

It Pulls power from the AC unit, batteries are primarily for backup. Otherwise, no it can not be powered with a power supply.

Either. It can use batteries or use the ac adapter. We always use it plugged in but it does have battery option.

You plug it in. I works pretty well. It has better power than the battery operated kind.

It works without batteries. When you pierce the wire insulation, thats hiw it gets it's power. The alligator clamp opens and you place it on metal for ground. That nakes the connection for a circuut wich activates the light.

It definitely is powered by a battery but I do not recall if it came with one. I seem to think it requires a 9v. Sorry that I could not be sure.

It uses both a plug and batteries. I have only used it with the plug which would be your best bet. But if you used batteries it reqires 4 AA.
