Strict gasoline-storage laws (no more than 25 gallons in most states) make propane generators your go-to. This five-outlet, 5,500-watt model powers essential items (fridge, range, etc.), is simple to operate, and shuts down automatically when it senses low oil levels to avoid any mishaps. A fold-down handle and never-flat wheels make it easy to maneuver. [$800;]
