Need another way to power up while on the go? The Off-Grid Backpack can get the job done. Sporting a slim 6-watt solar panel and rechargeable battery, and water-resistant fabric, it power your devices, while toting all your gear. Plus, you don't have to be a hiker or a rock climber to get your money's worth. Only three to seven hours of direct sunlight will generate enough juice to bring your phone, camera, or tablet back to life. Available on Amazon; $199.
