Drills are very noisy in the EMP and back-voltage - It is possible that high
voltage spikes from the drill damaged your inverter. You need a line filter
between the drill and the inverter in the future.

Imaginative cukka. This didn't hurt your Coleman MSW inverter,
something it wrong with it or there is an open in your related circuit
(fuse, breaker or connection). These cheap inverters (they are all
about the same) will stand up to a fair amount of abuse. No wonder
some people send this guy criticla emails...
