you need to have access to 120v outlet; unit comes with transformer which plugs into 120v outlet and connects by small wire to the unit.

The unit is actually powered by a USB which comes with it. It's very easy to use. You just plug one end of the USB into the unit and the other into the netbook

It does power unit but when plugged in Can not turn power off like the factory unit and actually have to unplug device or it remains on all the time. Kinda annoying but in reality not having unit on standby saves energy I suppose.

It isn't powered. It's just the flat bottom piece, two vertical tubes, some carbon, and plastic heads for the tubes. You need a power head or some other air-blowing device to make it work.

It's powered by the USB cable it comes with. I'm happy with this hard drive. It has an extra usb power cable if main usb output is not giving it enough power

This unit runs on USB power. There is no need to plug this into an electric socket.

We use the power supply and not a battery. Last week we had a power outage. When the power returned we simply turned the unit on and everything performed without retuning.

To plug in the IR unit the unit is powered by dc port but can be power by the HDMI port from some things like a dvd player but not all plug in will power the sw so the power can be used. I used the adapter

I can't directly answer your question but I can tell you that it is equipped with a mini USB connector, both for charging the device and for connection to a device to be powered by it.

Most of it is wireless and battery powered. If you add a UPS to the base unit and any horns you are covered.

Can't answer as I sent unit back right away as soon as I read don't use if engine is on - and that's the only way my power outlet have power.

It is not at all powered by electricity. There is a battery operated monitor but I don't think that would be an issue. We don't use that feature anyway.

It is powered by the C-Pap. There should be a connection on the back of the C-Pap where you push and twist the cord to connect it.

No. The unit must be plugged in to an outlet and powered on in order to function.

It can be powered by either. Don't waste your money on this product though. Very poorly made and breaks easily.

I believe it has a 110Volt power supply which converts it to 5 volts at the unit.

Nope. It needs to be powered. I could only get one item at a time to work. If I had 2 or more things plugged in, it wouldn't work at all.
