Many of those fridges, even though they only draw 70 watts, they need a
momentary "slam" of 600 or so watts to start the compressor. for the record,
the "digital" inverters from Canadian Tire can handle this, in particular
the 800 watt model. Last summer, I ran a cheap household/bar  Danby 4.5 cu
ft fridge off of an Optima Yellow-Top with this particular inverter (in an
RV).

YMMV
