Kill-a-Watt for only $16.95

Fri Nov 11, 2011 7:41 am

For those of you who don't know what the Kill a Watt is, it is a nice wattage/kWhR monitor that you can plug any 120 VAC appliance into, to check its power draw, and longterm kW/Hr usage. Its great to find those "phantom loads" in your house, or calculate your energy consumption.

If you used two of those through a "QIC240" (dual 120V combiner) box would you get a valid reading when charging a LEAF through a Ingineer modded EVSE?

Sounds plausible. Just add the 2 readings together and it should be right.

Not clear. I don't know if it depends on current flow through the neutral to function properly.

No.

The only current the kill a watt will read is the current used to energize the relay, and that is too small to register.

Also, my experience with the device while charging L1 is that it may be rated at 15 Amps, it doesn't seem to like a continuous 12 Amps. The prongs are soldered to the circuit board - mine got hot enough that one prong came loose from the board.
