How is this unit powered, batteries or electric, not sure why they do not indicate which?

I believe it was just electric. We returned it because the cd player did not work.

Electrical; 110. Don't know if you were hoping for battery; it appears that it converts to 12-volt DC for actual operation, so maybe somebody really clever could modify it.

The power source is battery.I think it is 9volts not sure but it is battery operated.

The unit does not use batteries. It is powered by a AC/DC transformer. It is not powered by line voltage. We have used this unit with DSL in the house, but always isolated transformers by use of a power strip with filtration.

Battery operatedI believe aaa but I don't have it to look as it was a gift.Hope this helps

We use the power supply and not a battery. Last week we had a power outage. When the power returned we simply turned the unit on and everything performed without retuning.

It's battery operated. But don't worry, it doesn't work with batteries, either.

It is electric, no batteries needed. I love this and I am ordering 2 more for my store. Hope this helps you.

No idea. It's electric... Plugged in to outside outlet on patio. Not enough for me to freak out at my power bill.

It is only battery powered. 4 AA batteries. We have 2 of them. They are loud. We like them. We had them hanging on walls for 3 months now and the batteries are still strong. We only turn them on/off when we leave home. WE are happy with our purchase

Unit is made of metal. It runs off both types of power. If you plug in both, it uses AC. If you lose AC, it run off DC.

It is not battery powered. It is powered from 125 VAC or 250VAC, switch selectable. When operating on 250VAC, only the Low power setting is accessible but that gives the same amount of heat that 125VAC would give on the High setting.

My mom says it's electric, have not idea if operates with batteries too, you might contact the seller and ask. I think it does but better ask the seller.

D batteries. They seem to last a long time. Also when electric is available you can plug it in. Hope that helps. :)

The unit is battery operated. The one I received did not include a battery.

It is to power the cordless, I didn't realize this until you asked the question and I checked. I thought the batteries were just in case you havepower interruption, that's not the case. I guess that would be another strike against it.

The Unit is powered by the input voltage of whatever voltage level you are monitoring (from 4v to 30v). For example, if the unit is plugged (correctly) into a 12v battery - the unit will display the current voltage output of that battery (11.8v, or 12.1v, and so on). The wires seen in the picture are simply for the input current from your source (Direct Current, DC 4v to 30v) Red = Positive, and the Black = Ground. Connected properly, the unit will then display the output voltage of your source. Again, this unit "monitors" the output voltage of your source... and is powered directly by that same output. In my situation, I am using the unit to monitor the output voltage of a 12v system. The unit allows me to gauge when it is time to charge the batteries again. So far the unit has worked wonderfully. Hope that helps?
