I like the idea of multiple small inverters and that might be my problem. I
wanted to run the small (4.2cubic feet) fridge off the inverter. We figured
earlier the fridge draws about 4.5 amps. However this fridge over powers my
500/800 peak watt and 600/1000 peak watt inverter when it is plugged in. So
do I assume it draws far more when it is powered on. Is there a number for
minimum watt inverter I need to power this fridge or is there a way to hook
both inverters up to get more capacity? Mike

I *think* the small (<300w) inverters are actually in the
90's, efficiency-wise. If it is the difference between a
$300 printer (was that a canon that was mentioned at that
price?) at 12v and a $40 printer and $40 inverter at 120v
(and $30 blender and $190 in rum), I know which way I'd
spend my $300 >;-P (hic)
