"small generator" How big is small? The small 750 W two stroke
jobbies can struggle with freezers/fridges as they don't have enough
welly to start the compressor motor.

That is a good point even a 1.5kW unit slows briefly when the freezer
motor comes on due to the very high surge current. A smaller unit might
well cutout to protect itself from a perceived overload conditions.

The load presented by the compressor motor from a standing start looks
very much like a dead short until it spins up.

Never tried my small 4-stroke "inverter" generator (Machine Mart "honda"
clone) on a fridge or freezer, but it certainly copes better with
inductive loads (angle grinder, circular saw) than its little two-stroke
predecessor.
