does it work only on batteries or can it use power also.

I have only used batteries. It doesn't have a spot for it to plug in. When using this make sure that the pads are attached correctly or it can feel like you are being stung.

No plugin available. It only uses batteries. However, if you buy a charger and rechargeable batteries it's cheaper.

It has both battery and electric cord. Also can work with 110 volt or 240 volt.

No. It only converts DC power into AC power. The batteryour is your electrical source.

no you have to plug it into a power source. that's the only way it will work.

It runs on batteries. You can plug in a 12V power source of your choosing. I use a universal power adapter that came with several plugs and found one that fits nicely.

It can run attached to a power source but only with battery in. Thus you slowly destroy the battery's capacity to hold a charge. If you can remember to turn it off when not using, then battery will last. Don't buy it if you have a choice. I have three so far -- they only keep working about 6 months.

You can power it two ways . Either with the included battery pack that uses 4 AA batteries or you can use the battery pack that also powers the car.

As far as I know, it only works while plugged in. At least that's how mine works.

Yes, it works off electricity, such as in the house. Can, also, be used in a vehicle where it would be powered by the vehicle battery.

Its like any other battery power device. It will last as long as the batteries. This one is plugged in (that's how it recharge) but it will last a little while on the battery. Can't tell how long exactly though. Not sure why you need battery only but that's definitely a high-end video monitor, i don't think it will last very long without a power outlet.

Same question twice...It uses both battery and corded power...it's small, though. I sent mine back.

No, it uses a rechargeable battery that comes with it, is fixed to it and only this item can use it.

To answer your question, yes, it can run solely on battery power for at least a handful of hours if it's completely charged prior to use. The company recommends a full 24-hour charge before using it for a prolonged period of time, whether it's plugged in or not. If you're just using it for an hour or two, it's fine to keep unplugged, but any longer than that, and I'd say plug it in.

It can run on just batteries. It actually last a lot longer that I anticipated. This is one of the best investments I have made in the caregiving of my elderly father. I know most people use it for babies but it definitely works well in any caregiving situation!

It only works by being plugged into an outlet. It is not made for batteries.

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

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