I don't know anything about electricity, so I don't feel like I can answer this. Perhaps the makers of the item could answer it.

Unfortunately I don't know, but I can say it did not appear to be a power burden on any outlet we have used thus far.

It draws its power from the TV through the HDMI port you plug it into. Very convenient.

How on earth do you think it would get its power? Dumb question. Of course it does!

It's powered from the computer's usb port. It has two usb cord connections, one of which must be plugged into a powered usb port on your computer. Check that your computer has at bleast one powered usb port. Most likely it has several.

It gets its power from the recorder. We use two of these with an Olympus recorder and it works well.

No, the unit powers from the AC voltage being metered (and the current measurement needed for the power calculation comes from a small toroid which is included). Thus four terminals: two for the voltage measurement and two for the toroid leads.

Dear sir, Thanks for your questions. Don't worry these questions .Because you just need to access commonly used power. best regards, Rainbow

There is a designated port that you plug in a device that you want to control the power. When that"controlling unit" draws power, the strip senses that and then turns on the power to the other outlet.

The plug uses 50mW with no load. That's with absolutely nothing plugged in to it. So yes it does use some power but its a miniscule amount.

Automotive Tools Distributor. It's their brand and no you cannot use electricity to power it. You need an air tank.

The power comes from an electrical outlet. It is relatively quiet. Ambient noise.

This is just the upper non electrical part of the unit. The body of the unit is where the power is consumed.

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

I thought it was as well.... I'm pretty sure it's actually accurate though. We really only produce power in high winds. The most we've ever done is around 1.5kw, and that was in 35mph. Typically we see around 100-200watts from 12-15mph winds.

Hi, most houses can handle the power. It doesn't cost very much to run it, if that is what you are concerned about. It just means that it's not cheaply made. Hope this helps.
