Gently stuff the wires and battery
into the case. It can be helpful to
glue the wires down. Set panel in sunlight, it takes
approximately 14hours to fully charge
LiPo battery. Or, plug a micro USB
cable into the charging module port
(the small one). Takes approximately
2hours to fully charge LiPo battery
from empty.
To charge your device, plug your
charging into the standard USB port,
turn on switch to direct charge from
battery to device.
