I think this is the most complicated topic I started
Wish I spoke electrical.
Those battery packs from CrappyTire wont work it seems, something about the on/off switch and not charging properly when its left on with stuff plugged in or something, cant remember what my dad said.
Most of the UPS have a 3yr warranty. I don't think the price is horrible for something thatll last 3 years potentially.
I just don't want stuff to start dying while people are at work because the power decided to go out the moment everyone leaves the house. While my shifts can run in excess of 14 hours, they are usually back within 8.
