Definitely. It's just a pass through for an outlet. I'm not sure it is the best way to turn off those devices, but that is for you to decide!

There are two cords that connect at the back of the unit. One goes to an electrical outlet. The other goes to the USB port on thecomputer. There is an off and on switch on the back. The unit can be turned off when not in use. When it is turned on you canhear the fan running, but it isn't that loud. I assume the a/c cord powers the unit and the USB cord transfers the information.Hope this is helpful.

Get a smart power strip. Plug the item you want cooled into the control (sensed) outlet. Plug the fan adapter into one of the controlled outlets. These come one when power flow is sensed.

It only has a USB chords that connect to you laptop. You don't need a ac power coz your laptop feeds the power to the keyboard thru the USB chords.

No there is no ac adapter. It does not require power. The switches on the front are mechanical, not electrical.

There are charging configurations that you can get that runs off the A/C or car battery that uses USB.

The unit has its own AC power supply and yes the computer needs to be on. It is a great product!

Yes. cannot introduce ac, hiss, hum etc because it is a non- powered passive unit.

No. After use I unplug from electricity. I use this only once a moth to backup my computers.

There is no ac adapter, only a usb cable which can be plugged into a computer.

Many newer computers have an option to keep the usb ports powered to charge devices even when the pc is off. There may be an option in your bios to disable this feature.

I think they were thinking that since most portable electronics has cords that can be plugged into an outlet it may be more convenient to have an a/c plug. Idk for sure though.

Unfortunately no, there is not. Probablly the only drawback. I've used so many of the other features, but it must be charged from AC.

We use it more like a desktop so it is almost always plugged in. No battery isues and it does get warm but not unusually hot. Not a big fan of the OS but otherwise happy with our purchase

No. This is a desk top computer. It's all connected with wires and a plug to the wall.

Hi, the nice thing about the unit is that it does not require either ac or dc power. It has a nice feel to it, so it does not feel cheap at all. A good option to help connect different equipment.
