Shipping & Payment
1. Input voltage: 4.7 - 24V (when the input voltage exceeds 12V, output current of 2A when requested to enhance heat dissipation ). 2. Charging voltage: 4.2V. 3. Charge voltage accuracy: +/-1 percent. 4. Charging current: 2A. 5. Charging current accuracy: +/-5 percent. 6. Charging: Blue LED light on, fully charged: blue LED off, (recommended to charge for more than one hour when blue LED is shimmering, for a more full battery). 7. Conversion efficiency: The highest 90 percent (5V input), at 12V input efficiency is about 85 percent, at 24V input efficiency is about 80 percent. 8. Switching frequency: 500kHz. 9. Input voltage undervoltage protection: 4.2V (TYP). 10. Battery intrusion current: 10uA (without battery polarity protection).
