extended battery

[chinesewoodbass]

I want to get an extended battery/case for my Iphone 4s. I've discovered there are a few: Mophie, EnerG4, Boost Case Plus. I'm sure I'm just scratching the surface. What do folks most recommend?[h=1][/h]

I like mophie. If you don't want a case google iPhone external battery. $40 will buy you 3000-5000 milliamperes in a carry around about the size of a deck of cards.

New Trent seems to be the favorite in carry around external batteries.
