Portable, weather-resistant, and incredibly lightweight, the Goal Zero Guide 10 Plus Solar Kit With Nomad 5 keeps you powered in the backcountry. The Nomad 5 solar panel can hang from your pack and charge smaller USB devices like your phone or can be used to charge the Guide 10 Plus. The Guide 10 Plus can then be used to charge rechargeable batteries for headlamps and other small battery-powered devices. The kit also includes a built-in flashlight to help you find essentials in your pack when the sun goes down.
