Does the 7" version have a battery or is the only power supply the AC/wall socket?

It doesn't matter, Coby has the worst product support ever. I purchased two of these from Coby, both were broken when I received them. One got replaced but Coby wanted me to send them $10.00 to return the other. I threw it away. Please look at a different brand.

Unlike a laptop, which has a battery, the B550 needs power from your wall outlet to run. Unless you buy an uninterrupted power supply (UPS), it will shut down when unplugged.

No built in power supply just regular AC plug to wall...I think it's due to the glass dome light effect....this product packed some power, big hit at party and everyone asked me where they can buy one!

It comes with a 12 vdc power supply that plugs into a 110 vac outlet. It can run on a battery but will take .5 amp during night operations.

The unit I purchased came with a power supply and there was no option to purchase without one. The supply itself is a small, simple 5.9v 1a supply; not worth much of a discount if it is not included anyway.

It comes with a power supply (wall wart) that connects directly to the unit.

Mine came on when I applied power. It has a controller to select the input and you can also turn it off. Also, the 7 inch only needs 5 volts.

no power supply. BUT the batteries you put in there last for such a long time, I am, actually, very shocked and pleased!

It is AC only. It just has a basic power cord. I really do not know why they call it portable, since it does not take batteries or charge with internal battery.

There is no battery, and no USB. This humidifier runs only when attached with the wall wart transformer to the AC mains.

no AC power, but it plays for quite a while on the batteries and delivers great stereo sound; albeit a bit narrow given its size. It also has two outs for head phones and audio as well as a 'socket" for audio in. I think it's a great little radio.

No power supply included, only a low quality 9 volt battery installed for testing at the factory. It should be replacedas soon as you get the unit.

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

No it does not. It take 4 AA batteries. But there is DC input if you decide you want to buy a plug in for the wall.

It's AC power only, in other words, you need to plug in to the wall socket.
