Electric cord only, no battery compartment. You really do want a consistent power supply for the duration of bubbles and that would take a lot of batteries.

No batteries: it plugs in. First one only lasted about 10 years; was still working, butgrips wore out. Can't imagine being without it. Does not go camping in the woods!Bashful3

It has a built-in rechargeable battery. The battery plugs in via a micro-USB charger (included).

It is plug in. No battery. See cordless waterpik if you want battery operated. http://www.amazon.com/Waterpik-WP-450-20009320-Waterflosser/dp/B000UWAWQU/ref=pd_sim_hpc_5

It does not use batteries. You have to either plug it into an outlet or the car.

It's battery operated, however, you can also use an AC adapter, but that's not included.

No batteries, must be plugged in to operate. If you want to use it somewhere other then in a vehicle an adaptor is available so you can plug it into a wall outlet. FYI - the switches were installed backwards on mine and at first I thought it wasn't working. It warms up pretty quick.

It plugs in, but has an internal battery that charges in case you want to move it around. Lasts about 6-8 hours on its own in my exp. with it.

Yes, it must be plugged in to be used. The good thing is, it won't run out of charge during use.

This unit MUST be plugged in to operate. Unfortunately it does NOT contain a standalone battery.

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

No, you plug it into a power outlet to get it charged. No batteries needed.

It has to be plugged in either to the wall or to your computer. There is no battery that can be charged to use it unplugged.
