With a lightweight housing, this NITECORE F1 is designed and strengthened for outdoor activities. Being a flexible outdoor power source with expandability, it comes with up to 90% discharging efficiency. You can use it to charge the batteries or use it as the power supply.
Capable of charging a USB device and storing power in the battery simultaneously. When the input current is not sufficient, the F1 will prioritize the charging of the external device, and store surplus power in the battery.
The finger-size F1 is made of high-strength, light-weight polycarbonate material. Its structural engineering is purposely redesigned for extra ruggedness to ensure ultimate safety in your dynamic outdoor expedition.
The gold-plated contacts effectively resist sweats, rain and fog, and protect metal components from oxidization and corrosion in outdoor environment while improving circuit efficiency significantly.
Thanks to the built-in intelligent charging circuit, F1 would automatically identify battery types, and select charging current and mode accordingly.
In power bank mode, the indicator LED lights on the NITECORE F1 would display the battery power status in different patterns.
