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.

Two people have replied to this question but neither one bothered to tell us HOW MANY batteries are required and if they are included!??

Electric. Plug it in. I don't think batteries would ever give enough power.

The power sources is eight double a batteries in the base of the unit. I have had nothing but problems with mine as water supposedly gets into the battery compartment and my unit looses power and shuts down

Sorry I can't answer that question. I always have it plugged in and do not rely on batteries.

It requires a power source. You can use a BEC, or a (4) cell NiMH or NiCad battery (4.8v-6v)

This device is not contain a battery. So you will need a fixed power source.

I, frankly, don't remember exactly. But I have an impression that it's supposed to be plugged-in, no battery.

AA batteries. There is a power supply availiable. 120 volt. I use the AA batteries. They last quite a while though. I try to keep my bag light so I don't have the kit just the labeler. It is the second one I have bought. I dropped the older one it only had edge guards and the cartridge holder broke off. I chose the plus with the complete guard it is slightly wider but the same quality.

You can use either power source. It comes with an AC adapter. I purchased a separate battery pack for travel.

It does not use any battery. It connects to your source and the power is derived from your source i think.

AC power is the primary source and the battery is the backup. FYI I used it for two months with just the battery and it worked fine.
