  • Asked by a guest
    Can it only indicate instantaneous wattage, or can it also indicate total kWh usage over a time period and keep a log of this? Answer:
    It does both instantaneous and keep memory from last reset. Meaning, as soon as you reset it, it starts at 0, then starts counting from that point and keeps the usage in memory. So if you want to measure a month for example, reset it on the 1st, leave it plugged in until the 31st and check the reading.

Great device .. display could be improved

Works as advertised, display is difficult to read unless straight on .. adding a backlight to the display would have been better.

By Vince F. on  23 Jan. 2021 (Digital Watt Meter (Kill A Watt) - Measure your electricity usage) :

Does what I need it

Does what I need it to do. LCD screen is a little hard to see unless looking at it almost straight on. It is a little tall for some plug points, but nothing an extension cannot sort for me. Lots of variable and valuable options. Costing is single rate applicable, not like other more expensive devices where you band them, but again, nothing material and nothing a simple spreadsheet does not sort out for you. Great device. Buying more as gifts. Very handy tool.
