One thought on “What's the best portable USB battery for the iphone and blackberry (i.e. mini usb and micro usb)?”
The best one I’ve found is the iGo PowerXtender. It takes 2
double AA batteries and uses the standard iGo tips so it will
charge Blackberries, iPhones, Android phones etc. I normally
get about 3 complete charges for my Bold per set of AA’s and
it takes about 1 hour to completely recharge.
