Does it have to be plugged in or can you run it solely off of batteries?

The batteries keep it from resetting but it doesn't run off just the batteries.

It needs to be plugged in to an outlet to run but there is no on/off button. Once it has power, it is on

It must be plugged in. It doesn't have a battery because it uses too much power for a battery.

Nope. It's battery powered only. You have to modify its scheme if you want to power it up with an ac adapter.

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, you don't need to plug it in, it comes with a battery, that is how the light is on.

No it does not run on batteries. It has to be connected to an ipod cord or dock.

It runs on batteries. Don't bother with the adapter. On batteries it can be placed anywhere.

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

It is not recommended to run it while plugged in. Like most rechargeable products, it it intended to run from only the battery. Properly charge up the battery before use, let it discharge and then recharge.

It's designed to be plugged in. I think it has a battery but it's only for when the power goes out.

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.

Hi. Unfortunately it cannot use batteries and must be plugged in. It is a good amplifier.

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.

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

It needs to be plugged in. The cord is about a foot long so really not portable.

I have the S1 and it does not need to be plugged in to the wall to run. As long as it is charged, it can be used anywhere without the adapter. I believe the S2 has to be plugged in. I'm not sure if it will run on batteries.
