How about a worse way?
I've measured constant loads using a $20 multimeter wired in series
with the AC mains plug.
Not good for loads that vary over time, and at $20 the Kill-A-Watt
is *definitely*

Mine reads 0.01 Kwh. It also does Power factor (and VA and watts),
Hz (most useful for home generators, but maybe UPSes too). Also
volts, amps, and hours.

I have to assume
#x27;ve been using it to measure a laptop, so
far the laptop has been running for 83 hours without consuming a single
kilowatt hour. For all I know we could roll over to that full kilowatt
hour at any second or it could take another four days to get their.

I have to assume the time it took to machine the metal and assemble the
whole unit cost them more in time then buying a kill-a-w
four days to get their.
