As its name implies, the Dualcharge Power Bank and Solar Charger from GoPole is capable of charging up to two USB devices at once, and can be recharged via its built-in solar panel. It features a 5000 mAh battery, a rugged, no-slip surface, a safety light, and a carrying loop that can be used with the included carabiner to secure it to your belongings. Should you run out of charge, or if it's a cloudy day, you can still recharge the Dualcharge using its micro-USB port.
