Power source? What is the power source?

As far as I can tell, the only power source for this camera is via a wall outlet. There are no batteries. Not truly wireless, as it does require the cord for power. I did shop around for another option that used batteries but was unable to find an adequate solution.

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.

Need to buy a separate source........ that is a good thing in my opinion. Most power supplies that are included suck.

The power source is 110V AC or 220V AC. It cannot be connected to a DC power source.

It does come with a power supply, however you can also put batteries in it to make it more portable. At least this version of the package DOES come with a power supply.

If by power source you mean battery.. The pen top unscrews where a USB port is exposed and this is how you charge it.. It takes about 5 hours to burn through the stored energy however I used mine so much that it no longer works. Very novelty but that's pretty much it.

Sorry, don't understand this question. Extra power supply to what? My review was about the battery charger and it doesn't come with a power supply. You provide the power supply by plugging it in to an electrical outlet.

This unit is powered by the USB connector on your computer. No external power supply.

It uses a cigarette lighter cord for operating power. It plugs into a PC using a micro USB cable for updating the software -- no additional power source required for that.

AC power is the primary source and the battery is the backup. FYI I used it for two months with just the battery and it worked fine.

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

Did your umbrella come with a power source? I got an umbrella with pole and that is it. What did you use for a power source?

There is no power source. This is just an antenna. It connects to the tv via a coax port.

It comes with a USB cable that has little adapters for charging different devices as well as itself. You are expected to provide your own USB power source.
