You’ll get at least 4 hours of smartphone usage from one hour of sun charging, making this little backpack a self-contained, powerful unit that lets you charge your device anywhere and any time.

Pack Fabric and UV-Resistant Solar Panels

It is 18 inches high, 12 inches wide, and 8 feet deep, weighing only four and a half pounds with battery and solar panels included. These panels are waterproof and UV resistant.

The output is provided in USB slots, while the unit also contains short circuit, overcharge, over discharge, and over temperature built-in protection for its battery.
