Please charge it under STRONG sunlight, do not charge it in cloudy day or the place through glass(e.g a window or car)
Solar charging is designed for emergencies, not a primary source of charging due to the compact solar panel size and sunlight intensity, it could take 21 hours under direst strong light to fully charge(there are 7-8 hours of sunlight per day). So we highly recommend charge the solar charger via an adapter or computer, which only take a few hours
Normally, it can reach 25% battery after 5 hours recharge under strong sunlight, so only the first light will on
The water drops are good, but please don't immerse in the water for too long.
