Portable Charger?

[androidftwx]

I have a Droid 4, got it a few weeks ago, and the battery life isn't too bad for me. Most of the time i dont get 4g, maybe an hour or two per day, but most of the time im on 3g/wifi. I can usually get through the school day which is about 6 hours until i have to charge at home. On weekends and break i sometimes use battery alot more playing games, listening to music, browsing, downloading etc.. So im contemplating buying a portable charger. Anyone here find a charger that works well on a battery of this size? I would like to get at least 60/70% of a charge out of it. Thanks for the suggestions!

There are cheaper ways to get better battery life. Juice defender is a great app that REALLY works for me. There's a free version, a $2 and a $5 version. I recommend the $5 version if you can afford it. Try Smart Actions as well. These are WAY cheaper options that work just as well as a portable charger.
