High Efficiency 13.5k BTU a/c = Smaller Generator?
Here' some specs (BTU/Compressor Amps/Fan Amps/Inrush-LRA):
Dometic (standard unit) 13,500/12.4/2.5/63
Total amps: 14.9
Colman Mach (standard unit) 13,500/11.9/3.4/63
Total amps: 15.3
Dometic High Efficiency 13,500/8.6/2.5/50
Total amps: 11.1
Coleman Mach 3 PS 13,500/8.3/2.9/58.4
Total amps: 11.2
Once started these high efficiency units use about 3-4 amps less current than the standard units. The Dometic has a respectable 13 amp (63 to 50) reduction in inrush/LRA/startup current. A very good thing for smaller generators.
Did notice the Coleman Mach 3 PS had much less reduction in inrush/LRA/startup current vs. their standard unit. Wonder why? Quite a few small generators will never have the opportunity to see the reduced steady current demands because they'll never get the past the higher inrush/LRA/startup current.
Typically these high efficiency units can be purchased for $650-$750. Purchasing one of these might be a better investment vs. buying a larger generator--say, one EU2000 vs. two EU2000i's--$1000 vs. $2100 :)
