I'm temporarily using a desk fan and only run it when I'm at home. I keep an eye out for rain but I really would prefer an outdoor fan for extra safety in the event there's a stray shower and I don't make outside in time to remove the fan.
The outdoor outlet has cover but I don't think it's GFI because it doesn't have the test/reset buttons. I'll have that changed.
I did find two outdoor fans at better prices but the reviews were so so.
