Again people, watts per hour is not right, nor kW nor amps.
Watt-hours, kWh and AH are the only units make sense "per" unit of time - running "for an hour" or "over an hour" is very different from **per** hour
I know it seems nitpicky, but 5 watts average rate for 5 hours means 25 watt-hours.
5 "watts per hour" or "amps per hour" no one can really know for sure what is meant.
AFAIK the Killawatt shows kWh natively over a period of time
How many kWh per 24 hours?
is all that is needed here.
Then for DC, just convert to AH per 24 hours.
