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.

There are plenty of solar chargers on the market, but we haven’t found one that gets the job done quite as quickly as Goal Zero’s Guide 10 Plus Adventure Kit (it charged our tester’s iPhone in less than two hours on a mostly sunny day). Plug your device directly into the dual solar panels via USB, or, if it’s overcast, juice up from the included battery pack, which contains four rechargeable AAs and a handy LED flashlight to help you find the one that died in your pack. No need to wait around for the sun to do its work—an external loop allows you to attach the device to the outside of your pack for powering up on the go. ($160, goalzero.com)
