So I live just north east of where Hurricane Harvey is making landfall in Houston. However I have always wanted to buy some kind of back up battery power and was wondering what others have bought. My plan is to have something that can keep the modem up and maybe provide power for small tablets cell phones. I live in a condo/town-home so buying the whole home generator is out of the question. I just want something to keeps things going for a couple of hours. Suggestions?
