how is this powered?

It is powered by a 12v transformer on the plug from the normal 220v outlet. Just so you know, my lights lasted eight minutes and then stopped working and the pump lasted a day. This is not a great product.

I am not sure how it works? It looks like to me it has to be hooked into a power source somehow. I could use some help here as well.How do you hook it up?

It's battery powered. And it works great especially when playing recorded C.D.'s. Which was why I got one.

It is not battery powered it has mechanical speings inside. However, ours only lasted a couple of months before it cracked.

It's cable powered. By a too short cable in my opinion. Battery powered would be so great, but no... Primitive mind hasn't perfected so a glorious thing.

you plug it into a wall outlet and then into the computer with a usb cable. so the power does not come from the computer

It is powered by battery. Otherwise we could not use it outside in the field. But I don't know for sure since I never received my RECEIVER yet. I have been waiting on mine for over a month.

It is powered by a 110/120 volt A/C cord. No problems so far with many uses.

It is powered by the tablet. You can charge the tablet by connecting the tablet charger to the side of the keyboard.

It's not powered at all. It just slides over your speakers in the bottom of the phone. Works well just doesn't carry bass well.

there is a voltage converter you simply plug in. That part of the is wired.

It has it's own power supply so I have not had any problems with powering anything. Also, since it has a separate power supply, it charges things while the comp is turned off. I highly recommend this unit.

Mine came with 3 different ways to be powered: it can be powered either directly to an electrical outlet, or by a double A battery or to your computer through USB. And it came with both cords and the battery!

I run this from the outlet, and it's been exceptionally reliant. There's a back-up battery for emergency power outage.

This unit is USB powered, does not need to be plugged to an electric outlet. The computer this device it connected to will power the unit using the USB cable.

No, it's battery powered...3 double A's. Mine is still using the same batteries I put in it originally, well over a year ago.

Its powered by the USB. It's a midi keyboard controller, meaning it connects to the PC and it uses ignite software. No actual software in the keyboard itself.
