I has a standard iPhone charger input, so it could plug into an outlet adaptor or a USB port on your computer.

No battery, plugs into an outlet. CAUTION: phone's case must be removed or it will not fit- a poor feature.

It plugs directly into an outlet. Beware these units are highly unreliable, read my review for my results. They are cheaply built and have a high failure rate.

It plugs into the wall. I leave mine plugged in all the time and use it at home.

It has a cord and needs to be plugged in. I use a heavy duty (orange) extension cord, and have had no problems with it.

It has to be plugged in to work. No batteries, but has an on/off button. I have it sitting on top of some files in the lower part of my desk as it doesn't really radiate a lot of heat unless it's close to you. I like it though.

It must be plugged in. But it does have a battery because there is a CAUTION: Risk of explosion if battery is replaced by an incorrect type.

Yes, it has to be plugged in. It does not come with a battery adapter. I had an outlet on my porch within reach, but most people probably need to use an extension cord.

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

No, it does not plug into an outlet at all. It only uses batteries and plugs into the telephone jack.

It plugs into the wall. On rare occasion it will spill water a little bit, so a battery wouldn't really be a great idea for it. I will say that I love mine (I have 2 because we have twins) and have found them to be the best out of every other brand we tried. We've had ours for over a year, I even sent some to my sister to keep at her house for our visits - they are that good!
