Does this need to be plugged into a wall to function or does it run on batteries?

It draws its power from the TV through the HDMI port you plug it into. Very convenient.

Unfortunately the power over HDMI did not work for me, for some reason my HD television couldn't supply enough power to the machine and I didn't want to have my playstation on all the time in order to power the device. You might need to connect one of the HDMI slots on this device connect to a power outlet through a HDMI to USB cord or some other method.

It runs on either 12v power or 4 C batteries. I keep batteries in it but when you plug it in it uses 12v power

No, plugs into the wall, but has a cool feature in that it can be set on a timer to go on and off at scheduled times.

It plugs into a wall with an included adapter. There are no batteries needed. You use it without any cord as it's wireless. I usually plug it in once a week only and it stays charged up nicely.

It does not need to be plugged into the wall. It can be plugged into extension cord. That would work.

It comes with the AC Adapter to connect to the wall. You do not need Batteries for it only the AC Adapter.

This speaker requires batteries if you want to have it portable, but if you have no batteries it can turn on and play just as well if you plug it into the wall. The batteries are just for it to be completely portable, but the plug is also portable so just bring that around and look for an outlet to plug your system and there will be no need for batteries.

Hello, I have a few of these. It runs on electric plugged into the wall. But I had an electrician wire a plug on mine so it can also use a 12 A 7 V battery too. It works great on both. Hope this helps.

It plugs in to the wall using an AV adapter. I believe you can use batteries as well. DDs I think.

Does not operate on batteries. Needs to plug to wall outlet or power through the USB cable into the computer.
