The charging time for the Quadra Pro USB Solar Power Bank is 2-3 hours when charged through a wall outlet and 8-12 hours when exposed to direct sunlight (note that charging times may vary in overcast or indirect sunlight). The green light will illuminate indicating when it is charging via solar power.

The 4th light will continue flashing for as long as it is charging charging via solar power or through an outlet!

Customarily, it only takes 2-3 hours to fully charge via an outlet.

After the full charging time, you can unplug the device and press the power button to check the battery level, indicated by the blue lights on the side (4 blue lights signal a full charge).
