Does it need power from the wall or can it run on USB or does it have battery power? Thanks!

It plugs in the wall. No battery. So not really portable but it is lightweight.

It is powered by an included wall wart plug. It runs on a lithium battery (internal) for hours when not plugged in.

Hello you do not need electricity, it runs on the internal battery. When the battery is dead you purchase a new unit. That is what makes this unit so handy you can put it anywhere on a shelf, end table, bookcase on a wall. It doesn't have to be mounted solid to anything. Ernie

This one uses batteries, other models use wall energy as well but not this one. Hopes that is helpful

No it won't run off USB I imagane that the designers figured you would not be useing this away from a power source.

The unit comes with a wall adapter that will run 100 - 240 VAC. The adapter converts this to 12 VDC which is the power connection to the unit. It also runs on batteries.

It uses a standard 110 wall plug. I think it's way too powerful to run on batteries, and there isn't a provision for batteries.

It requires standard USB power which is 5 Volt, 2.5 Watt, 100mA. Mine came with a 100-240V 50/60Hz 2 prong wall adapter, but I have never used that.

It take batteries. It does not have the option to plug into the wall. The batteries last a very long time though.

It uses wall current and can use batteries. Wall current should be your primary source as batteries don't last very long in this device.

No, it is a stand alone device. You can plug it in to the wall to save battery power.

It runs on USB power or three AAA batteries.There are two cords: one that connects to the headphone outlet for audio, and one that connects to the usb outlet for power.

No it will not run off a wall outlet. It's suppose to be for your computer.. and since it's connected to the computer motherboard, it uses a DC voltage output from it.This is also not a USB fan. Based on your question, it's likely not what you want or need..

To power it through the wall you have to buy the USB plug, that's how I power it, I haven't even hooked it up to my laptop yet.

No, it does not run on batteries. Both the camera and the monitor plug into the wall.

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