If you actually use your iPhone’s best features--the 3G network,
push notifications, Wi-Fi, Bluetooth, Location Services, all those
bells and whistles that make it so awesome--you’ve probably noticed your
battery needs recharging every day or two at least. We never leave home
without the cable and AC adapter that came with our iPhone, so we’re in
luck as long as we can find a power outlet or USB port to plug in to.
But wandering beyond walls and away from computers requires some extra
gadgetry to keep our iPhone charged, namely Belkin’s Dual Auto Charger
for the car and the iPWR SuperPack backup battery for everywhere else.
