MiniPAK, a handheld fuel cell charger
- Yaggo 16y agoI see two problems: 1) The refill station has a lifetime of only 1000 hours of operation (1000 refills) and costs $500! C'mon, the best li-poly batteries has lifetime of 1000 cycles! 2) With 12 Wh per 83 g, the stick has roughly same energy density than the best lithium-polymer batteries, and battery chargers don't die after 1000 hours of operation.
