I had rented a Self Storage unit for a shop just to play in.
I ran it on I think a 5K Gen. All my tools worked fine. I had a table saw, lathe, band saw, planer and joiner plus the everyday plug in power tools.
My lights were fluorescent and they worked fine.
As far as my tool go, everything was good.
Then Hurricane Ike hit. I had been out of town at the town. The water in the marina reached a height about 16' above normal. When I got back, i could not even get to the marina for a few more days. My boat was fine, the marina was flooded and lost power. I went to my shop and brought back my generator. Lights, TV AC all worked fine except for anything I had running through my inverter (Converts 12V DC) from car/boat batteries. Apparently, modern electronics just does not like the output from generators. my old generator was i think a modified sine wave. Probably, if you spent $1000 on a generator with full sine wave, you might not have the same problems i had with my $400 generator.
But back to my original statement, The $400 cheap gen. ran all my tools with no problem.
