Medis Technologies, in New York City, started selling a recyclable fuel cell with a reusable power management cable for US $34.99, with fresh power packs for $20. This makes Medis the first to market. But competition is coming later this year from a number of companies. The initial version of Medis’s cell, the Power Pack Portable Charger, provides 1 watt and is intended for only the low-power end of the gadget market—no touch screens, for example — and only four or five full charges at that.
