Compatible with Sony NP-FW50 battery
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.
Thoughtful design to accommodate the needs for enthusiastic photographers who carry primary and backup cameras, eliminating concerns for power shortage for either camera.
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.
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.
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.
The USN1 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.
