Backcountry Power: Bushnell POWERSYNC SolarBook 850

[Expedition power]
For the long-haul hiker, this five-solar-panel, 2,200 mAh dual lithium-ion power pack helps reduce clutter by folding up into its own hardshell case, and the four-light display made for easy tracking of power consumption. Two USB ports let you charge two devices during breaks; our Colorado testers recorded a four-hour recharge for the power pack in direct sun. Once it was topped off, we were able to juice up our half-full Galaxy Note 8 in three hours, and then we netted two smartphone charges when they were at 25 percent power. Bonus: The case can double as a carrier for your tablet. Ding: price. $357; 24 oz.; bushnell.com
