Brookstone this year will start selling a portable fuel cell able to charge smartphones a dozen times
Neat, a portable fuel cell. You get to charge up your Cell phone (or any device that charges via USB) 10 to 12 times before it runs out, and the replacement cartridges are only a few bucks.
No word on what the unit itself will cost, but even if it’s pricey this could be a worth while investment for those outdoorsy types.
Very handy for travelers, campers, or people just too often away from standard power.
