If you're like us, coffee is essential even off the grid. Powered by a propane or butane canister, the Brunton BrewFire Duel-Fuel Coffee Maker ($120) can make up to 8 cups of java from the comfort of your campsite. Simply pour in your favorite grounds, add water, turn the knob and flip the switch. Within minutes, the Stainless steel carafe will be filled with hot, steaming coffee.
