Please... you don't need a UPS (which is for computers) in a major storm outage. If you had a whole home-oriented power backup, that might be something worth mentioning because you could use that energy (much more than a UPS has) for useful things like lighting and cooking raw foods or sanitizing water.
The only way I see a UPS really making sense is if it was used strictly to power and recharge a cellphone in the event that some form of emergency local towers were still in place.
My main point.. you don't need computer technology to get through bad situations -- you need things that have major impacts on survival. Food, water, shelter.
