Portable Crank
March 27th, 2011
Which type of portable charger is best, solar or crank?
I am going camping soon and am looking for a good portable charger to take with me, whether solar or crank, and am trying to decide which would be best to purchase to charge an iPhone 4 and an mp3 player and maybe a Nintendo DS.
I don’t actually know about either one, but as an engineer I’d suspect that either one needs some kind of output regulator. Especially a crank one, or you’d overload the battery you’re charging. So I guess it’s a matter of cost, whether you want to do the work, yourself, for a couple hours, or let it do the work for you. And solar doesn’t work so well when there isn’t a Sol to provide solar energy into the solar cells.
