Create A More Powerful Battery-Powered USB Charger

People have seen the 9V battery chargers that will charge your USB devices, but now there is one that takes 2 AA batteries! Using 2 AA batteries appears to give a longer battery life than traditional 9V homemade USB chargers. It will power the iPod Video for 3 hours which is equivalent to one full recharge.

The nice thing is that you don’t have to go and scrounge for the parts yourself because there is a kit available to purchase. Now you get the fun of assembling your own charger without the hassle of running from store to store looking for parts, and it is only $20 (a little high but not too bad). However, there is some soldering needed but it doesn’t look to intensive.

These Altoid tins are quite popular for these chargers because they fit all of the parts snuggly and make the charger very portable. I like that is uses AA batteries so I might have to give this one a shot.
