| The Bottom Line | The Voltaic Backpack's thoughtful design and solar-charging features shine for keeping cell phones, handhelds, MP3 players, and digital cameras charged away from electrical outlets. | The Revolve XeMini Plus is an easy-to-use device that will deliver emergency juice on the go. You can't rely on the sun as your primary charging source, but the green features remain a nice benefit. | Despite its limitations, the iTech SolarCharger 906 does work as a quick, easy, and eco-friendly solution to charge up your portable devices. | Lightweight, quick, and easy to use, the i.Sound Portable Power Max battery is a great way to keep your USB gadgets going when a wall charger isn't accessible. | The Trans4m is a useful all-in-one charger for most of today's portable electronics. |
