And pretty darned cheap to run, too!
Um … what is this; what does it do?
It measures the draw of power on an outlet (in this case, my printer), then with the price you pay per kwh ($0.116 /kwh for me), figures out what it costs to run…in this case, half a Starbuck’s Black coffee a month.
Love the Kill-a-Watt.
With it I was able to confirm that a new server I recently set up uses 1/2 the power of the old one it replaced.
@Mike_Miller Thanks, Mike. Since we can only manage assets we can measure, the Kill-A-Watt is a good tool for wisely using electricity.
What was wattage draw? Also pla or abs printer?
Hmm cost more than twice that much for power here; $0.2673 per Kwh. Maybe we have to pay more for 240 Volts. 
@Karan_Chaphekar I dunno. It’s a 40 amp power supply, but the printer doesn’t pull NEAR that much. Honestly, the controller, three motors(edit: 4 - forgot the extruder), a small fan and the cartridge heater…obviously not a lot.
@Ben_Jackson Heavens! $3.00 USD a year then! 
Even with a heated bed, a normal printer only draws around 100W when printing (measured). Even with expensive 240V power, it really doesn’t sum up to much.
