For lightweight travel, check out the Goal Zero Guide 10 Plus Adventure Kit ($160). It comes with four rechargeable AA batteries (with an adapter, it’ll charge AAAs, too), and will also connect to any device that can carge with a USB cord. In bright sun, the AA pack fills up in three or four hours. Plus, it’s compact and light at two pounds.
