Got the Kill-A-Watt and tried it out with some chargers and trailer batts run down low to accept the amps no problem, powered from a Honda EU3000is (13 years young ) rated 2800VA Tests run at sea level
I was not able to capture the initial surge numbers like Mr Wizard did, but the gen was set to "eco-off' and was warmed up. Very slight increase in noise on start up, so go with Mr Wizard's numbers on surges
Lots of numbers--try to stay awake!!!! :) (unloaded AC was 127v)
Note- KAW numbers jump around some, so had to eyeball an average, but these numbers work out fairly well, so no nit-picking! :)
A. PowerMax PM3-100 (100 amper) "PF corrected"
122.7v x 15.57a, 1854w, 1910VA , PF 0.97
DC Output 102a converter set to 14.8v = 1510w /1854w = 81% efficient
OR using battery voltage 13.95 = 1423w/1854w = 77% efficient
B. PowerMax PM3-75 (75 amper---same as Mr Wizard's so compare the numbers in previous post. Note the higher VA when you use a different generator that has higher AC voltage--in this case it makes it doubtful a Honda 2000 can run a PM3-75 ????)
123.8v x 13.64a, 1241w, 1693VA (added on edit) PF 0.73
Output 75.0a converter set at 14.8 = 1110w/1241w = 89% efficient or using battery voltage 14.08 = 1056w/1241w = 85% efficient
C. PowerMax PM3-55 (55 amper)
124.7v x 11.06a , 980w, 1383VA (added on edit) PF 0.71
Output 56.8a set to 14.8v = 840.6w/980w = 85.7% efficient, or using battery voltage 13.7 = 778w/980w = 79.4% efficient
D. Vector (B&D) 1093DBD (40 amper)
125.4v x 8.4a, 680w, 1063VA (added on edit) PF 0.64
Output 40.4a (it does 14.8v so using that) = 598w/680w = 88% efficient or using batt voltage 12.8 (VEC readout) = 517/680 = 76% efficient
E. Parallax 7355 (55 amper but on long wire trailer plugged into Honda)
126.2v x 4.95a, 410w, 620VA (added on edit) PF 0.66
Output 25a converter fixed 13.8v = 345w/410w = 84% efficient
Anyway, there is some to add to the pot, so anybody got some Iota numbers?
