Unlike the finite energy stored in a battery pack, a USB solar charger offers a tiny power plant that can generate power for your phone and small electronics to keep them charged when the sun is out—you can even use one to recharge a power bank and save that energy for later. After spending more than 60 hours testing 12 models, we’re confident that the BigBlue 28W USB Solar Charger is the best portable solar charger for people who need to charge their gadgets and stay connected in an emergency or when they’re off the grid.
