Does this power operate without electrical power?

Yes! I work fine because it is not running on a modem. This is an awesome phone and I give it an AAAA rating.

No. It runs on electric which can be somewhat of a pain if using it alone. It's got a lot of power and does an amazing job.

It has a rj45 cable (network cable) that goes from the controller to the device. No power is needed.

I don't think there is supposed to be power there, I think it is only supposed to switch power you bring in. I'm not positive, but that is how I'm using it.

No, it does not use much electricity because it is really just a fan and does not have a heat source.

Hello, We believe that the MRHF270320 will not operate WITHOUT electric power. The AC powers the on/off switch, but once ignited the electricity "pull" is minimal if not nothing at all. It would be best to view at the operating manual for the unit.

It doesn't have an automatic power on/off for sure. The normal power switch that's in that back doesn't really need to be switched off when not in use, no but if you do turn it off it won't be a problem.

Yes it does because it is the only way it gets power. If you didn't, it would be like buying a scanner and not getting an AC adapter to make it turn on.

No, it doesn't. It's necessary for the unit to be plugged in to a power outlet for use.

I never installed batteries but as I recall it needs them or the AC power to operate.

It is powered by the USB connection and doesn't require an additional power supply. It is not wireless and must be connected with the USB cable.

YES. It draws no power unless a device is attached. Cables only attached drew no power. I used a Kill A Watt to confirm. Hope this helps.

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.

No, but it doesn't need one. Power consumption is exyremely low when it is on standby.

Correct. Will work without power. Has a manual switch as well. Great switch for the price.

That is correct it requires power, however, the control box under the sink has abypass and will allow it ti work without power. See the manual on Kohlers website..if I recall the bypass is round and white and turns.
