  1. How i wish we had one of these during the Sandy hurricane! I am in NJ and everyone in my house has iphones (those of course died in the first 24 hours) and this little gadget would be really useful 🙂 Definitely adding it to a stocking stuffer list for next year. Thanks!
    PS. Just looked at the price, maybe not a stocking stuffer, but a side gift to something else lol
