The battery charger is a great way to charge phone at night. The unit itself has plenty of wire and cable connection option for the different devices which means a lot of possible ways to charge your device. Unit is about the size of a small book but if you're looking to carry it in a day pack, ounces equal pain, and the batteries are getting up there. Then again, the ability to charge the AAs allows for less batteries overall to be charged. I've been using it in the Sonoran desert now for about two weeks and can't complain at all. Other people with me are using cheaper chargers from other companies and the goal zero is by far the best out of even the more expensive ones my friends are using.
Pros: Usability, battery pack
Cons: Weight, cost
