Ideal for fastpacking adventures, camping trips or all-day crewing at ultras when electric-outlet access is limited, the powerful, portable Solar Power Bank 4000 with built-in USB cables uses a small solar panel to charge up electronics on the go. It can store its own energy, recharging fully in five hours via USB or approximately a day’s worth of direct sunlight—though, unlike many comparable products, it can still gain a charge even in indirect sunlight.
