Attention 1. Please charge it under STRONG sunlight, do not charge it in cloudy day or the place through glass(e.g a window or car) 2. 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 20 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 3. There are 4 lights, the first light means 0-25% battery left, the second is 25-50%, the third is 50-75%, and the fourth is 75-100%. Normally, it can reach 30% battery after 7 hours recharge under strong sunlight, so only the first light will on
