But 300 hours may represent many years of occasional use. If, OTOH,
these cheap motors are not good enough to run for 5 or 6 hours at a time
without crapping out, that's a different story.

The biggest problem with residential generators is the quality of the output
signal. Some electronics, including stuff you'd want to run in a power outage
(range, furnace thermostat) can be fried by dirty AC. Those same generators are
fine for running portable tools and other simple devices.

I so far haven't seen companies advertising any of specs as far as how good the
output is.
