I found my old notes on a test I did where I ran chargers from inverters.

I noted the inverter's watts display vs the amps to the battery on an ammeter, if that is anything like what the Kill-a- watt would do.

All numbers rounded roughly.
(Non-PF corrected chargers, MSW inverters)

50 amps - 1000w so 20 to 1
32 amps - 630w so 19.7 to 1
20 amps - 320w so 16 to 1 (different inverter for that one)

So that 20 to 1 might not be so crazy after all! :)
