It has a funny name, but the Solarrific Solar Portable Power Supply from Convenient Gadgets and Gifts has a serious purpose. This external power supply comes with eleven connectors to fit most any digital device, including iPhones and iPods. The Solarrific is 3.25″ X 2.25″ X 0.59″, so it’s small enough to fit in your bag or even your pocket. Inside, there’s a polymer lithium-ion battery with a 2000 mAh capacity. Rated input voltage is 5.0-6.0V DC; rated output voltage is 5.4V (+/- 0.1V). You can recharge the Solarrific with solar power (takes about 35 hours), with a USB port on your computer, or with the included AC adapter. The life cycle of the battery is about 500 recharges, but even after 500 charges, it should retain >80% capacity. You’ll get a fabric pouch to hold the Solarrific, the AC adapter, and all the connectors. The Solarrific Solar Portable Power Supply is $39.95.
