THE SELL: Mobile solar power for your devices. THE TEST: This lightweight (6.3 ounce) panel charged our phones in two to four hours while tied to a moving backpack on an Arizona trail (though it didn’t charge well in low-light conditions, as it claimed to). You can also pair it with a power-storage unit like Brunton’s Inspire ($72) to maintain a steady source of juice. Honorable mention: we also liked Tech4o’s Pocket PowerPack ($100; tech4o.com), which is slower but includes AA and AAA chargers. THE VERDICT: For serious expeditions wanting power for communication devices, this is a solid choice.
