Professionally Made to Exceed Expectations

Good riddance to the outdoor charging conundrum, breaking loose from technical constraints inherited in conventional camera charging.

Compatible With Multiple Input Sources

Easily copes with situations where AC input is not possible.

Compatible with an array of portable power banks, solar panels, USB adaptors, can be used in conjunction with Nitecore’s F1 flexible power bank to ensure endless power supply.

Dual Slot Specifically Designed for Enthusiasts, Tending to the Needs of Both the Primary and Backup Cameras

Thoughtful design to accommodate the needs for enthusiastic photographers who carry primary and backup cameras, eliminating concerns for power shortage for either camera.

Smart Charging Management System

The USN1 takes advantages of the smart charging management system; it monitors battery status, showing battery voltage, charging current, temperature and battery level and other parameters; and automatic adoption for the optimal charging modes between CC and CV.

Battery Status Monitoring

Once the battery is inserted, the USN1 will proceed with an initial low current test charge to diagnose battery status. After the diagnosis, battery status will be shown as Good, Normal or Poor.

Battery Recovery

The USN1 will attempt to recover over-discharged batteries when inserting in the charging slot. Upon successful battery recovery, the entire battery level indicator will flash to represent that a battery has been successfully recovered.

Reverse Polarity and Anti-Short Circuit Protection

The USN makes use of the mechanical reverse polarity protection. Inserting incompatible batteries or incorrect battery installation will prevent the initiation of the charging process. The error message “EE EE” will come up on the LCD display when a short circuited battery is installed.

Made from Durable PC+ABS (VO) Fire Retardant Materials

Designed to cope with changeable outdoor environments

Cable Storage Trough

Trough storage design allows for maximum space utilization and shields the cable away from potential damages.
