With Goal Zeros’ Yeti 1250, you’ll not only be prepared--you'll be be a local hero, able to power your wall-sized flatscreen and the fridge. This silent recharger, which can be juiced with solar panels or stored with a wall socket charge when the power is still flowing, has multiple outlets compatible with everything from a GPS unit to a refrigerator. It'll run a laptop for 30+ hours, keep a full-sized fridge going for four days, and maintain subzero temperatures in a chest freezer for over a week. That means that not only will your buddies call you a game saver, but when you're still out of power three days later, your wife will be on board. Available May 2012, $1500 wall powered; $2000 with solar panels. goalzero.com.
P.S. It's 104 3 pounds, so not really suited for the backcountry, but Goal Zero does make smaller sizes.
