I was looking for a portable charger for my BlackBerry curve that is small and light enough to be put in a purse, which requires no cable connection and allows to charge 2 without having to be recharged itself. I found this article which corresponds perfectly to these needs. It comes with a small bag (only regret is not padded) and it has a charge indicator, which is very convenient. I'm happy with my purchase! Now I do not know if it is enough to iPhone or other phone like this, a little more greedy than my BB curve.
