People who are trekking in the wilderness, stranded at disaster sites or living in developing nations all have one thing in common - lack of access to an electrical infrastructure. Solar charging devices such as the Solio, iCharge and Joos Orange have been designed to meet the needs of some or all of these groups. One of the latest such systems, Horizon Fuel Cell Technologies' Sunbox USB 3.0, is particularly versatile.
Readers involved in foreign aid might also be interested in Horizon's entrepreneur package. It allows small businesspeople in developing nations to charge ten Sunbox battery packs at once, which can then be rented out to members of the local community.
