You are, no doubt, already familiar with the mini power plants known as camp stoves. The ReadySet is a different kind of mobile energy source that generates and stores electrical power generated by the sun or pedal power. While it wasn't originally designed for outdoor recreation, it might find a happy home in your excursion kit.
The ReadySet is the work of Fenix International, a San Francisco-based company that got its start by creating renewable energy solutions for economic development and emissions reductions in off-grid communities in the developing world. Visiting small villages in Africa, Fenix International CEO Mike Lin discovered that entrepreneurs were scavenging old car batteries and using them to power up cell phones and other small electrical devices. Despite their lack of electrical grid access, more than 600 million people in the developing world are using cell phones. So the need for a reliable, clean and mobile power source was obvious.
