Portable Charger is specially charger for our Li-ion battery cap lamp, the charger is high reliability and high efficiency, convenient to carry with small size, light weight.
charging theory:
Stable current stable voltage charging, the charging current is 1000mA , voltage is 4.2V , charging time is about 8-12 hours. The circuit designed with perfect watching and controling system, able to automatically watch and control charging process. At the beginning of charging it is stable current charging at 1000mA, the charger indicator is red color. When charging voltage reaching 4.2V, automatically turn to stable voltage charging, at this moment the battery is charged about 70%, at this moment, the charger indicator start turn into orange color and current is reduced step by step. when the battery is charged enough it automatically powered off to stop charging and charger indicator display as green color. (note: you can charge at any time, no need to wait to charge after use up the power, bring forward charging is better for prolonging the life span of the battery).
Technical Specifications:
1. Input the voltage: AC110V-240V, 50-60Hz
2. Output the voltage: DC 4.20 3. Export the constant current: 1000mA 4. size: 125x55x80mm; weight: 0.35kg
