Jon, I am not sure I would listen to Ruben.

Looks like the surge protector he purchased didn't quite work, lol.
LOL.
Actually I had to get a online ups for a commercial site it was a radio paging system.
It had a generator but sometimes the generator would not start up and then of course the pagers would not work. for a while
And I needed at least 3 hours of battery time.
Ended up paying $6,000
So I looked at the smallest one for my home and it was around $1500.
Never bought one of them for myself.
Just consumer grade APC units.
