Going camping need a portable iphone charger

[MastahRiz]

This is what I use, and it does a decent job.

how can you buy something that doesn't even mention the strength of the battery?

Edit: nevermind, found it on the kensington website instead. Capacity is 1000mAH

This is what I'm using right now : amazing and super fast charging (4 times faster than regular USB) - which is the main reason why I got it. I needed to not have to plug my phone in all the time. Also, the battery is a 3600 so it should be able to charge your iphone 4 through 2.5 full cycles or better.

I know this is old, but you can get a USB charger from a dollar store or Staples on the cheap that takes AA batteries. Just be sure to recycle them when you're done.
