The power source comes from the computer once you conect the jacks from the hub. Once they are conected then you can plug your headphones and speakers into the hub. Your speakers will no doubt require a dedicated power source be it batterys, USB or other.

No, it plugs directly into your PC or other device, acting as a conduit for your audio and mic.

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

My impression is that NO, this is a power source. It is used when one has a DC powered appliance and wants to use the appliance with AC power.

Yes, you we'd need an extension cord to power the unit. I had an outlet installed for neatness and not to stumble on the extension cord, regularly.

No you have to use the power adapter supplied. Unless you rigged up a 12 volt DC battery near it.

Require a power supply: No; Batteries: My book says "to provide back up power". Others have mentioned that the batteries don't last to long

No, to power it, it came with a USB cord that can connect into a USB port on a computer or USB wall adapter.

This unit isn't battery powered. Don't know why they don't show the cord in the picture. You need to plug it in to a wall socket. :-)

No it doesn't, but they are very inexpensive. Besides you won't need it once you've set its output.

None, comes with mounts so all you need is a power source and a togle switch.

No external power source required. I added the required AA batteries in order to keep the call memory intact. However, if you want this as a wall phone, you are wasting your money. The receiver does not stay in the cradle.............

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

No. It's powered by a small AC to DC adaptor. You do need to factor that into the installation.

No, it does not. It won't function as a hub without the power source either (at least not to devices that require power, eg, my WiFi card)
