solar fashion backpack charger

solar multi-purpose charger system products introduction: The advantage of Solar System is safe, reliable, without pollution and noiseless, long useful time, easy assembly, easy move. This system contains overcharge, over-discharge, over-temperature, overload, short circuit protection. Principle of operation: During the day, solar cells fully absorb the light energy. As the same time, battery is charging, saving electrical energy which comes from the transformation of solar energy. When the lamps need power, you should fit them on and turn on the master switch. Then the system will automatically start to supply power for loads or charging batteries.
