12 VDC, 4.2W. I used an 8 cell AA battery pack for my use. You could use any DC power supply generating 12 VDC & able to supply .4 A or more. I tried it at 24 VDC. They run for about 30 sec. & seize up for some reason. So I would not suggest trying run them on much more than 12 VDC.

I use this little pump at a remote bird blind water feature with a 12 VDC car battery, solar panel charger, and a charge controller.

I can't tell you. I returned the item. It didn't power the item I needed. Sorry

Nope! It is a passive capacitive stylus, so it does not require a power source. Only the magic of conductivity.

Yes, the power source charges battery. This is a cheapy made unit but can be helpful. I went to radio shack and bought toggle switch to put in between the connection to battery so I could turn off as soon as possible because batt. is so small and used x-mas ext cords for hookup.

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

There is no power source. It uses the pressure of the water supply. I followed the hookup directions that came with the pump, and it works great. Instead of the drip, drip, drip, the pump goes "ffftt, ffftt" occasionally.

This device is not contain a battery. So you will need a fixed power source.

The battery is a backup in case of power interruption. From a practical viewpoint you need a low voltage power supply.

it requires a DC power source. If you want to use AC power you will have to convert it to DC.

The power source is a house current (electrical outlet) this device can be either run through your computer for recording purposes (software included) or connected to a receiver as it has cables for both. Great machine for digitalizing tapes or listening to them. Only problem I had was the Apple software you must work with to record to computer. But it does it's job although more settings would be nice.

This does not come with a power source, you're gonna have to buy a PSU separately. There are three slots for 5.25 inch drive bays, which you can put disc drives into.

It is a simple input/output arrangement. Power source is the input, supply to whatever device you want to vary the speed of is the output. This will only work in one direction, unless you swap the output polarity to run it in the opposite direction. Doesn't matter whether the + or - is the control path.
