UPS (uninterrupted power supply) or battery back ups for Home PC
's may be of usefullness down the road. ( since the storm has come and gone already)
They varry in size and amnt of battery back up life you get out of them.
They may only have 3 or 4 plugs that are on the battey side, the others are just normal outlets, so you may need 2 of them depending on how many items you need on the battery back up side vs just being on a surge protector.
Not sure how long they will be good for time wise. it will depend on how big of a battery back up you get and how much juice the items take that you plug into it.
