Operating Instructions

This product is designed specifically for Sony NP-FW50 camera batteries. The USN1 supports charging batteries in both slots simultaneously. The output current is adjusted automatically according to input current to reach the optimal charging setting. This product shall NOT be used with other batteries not specified in this manual.

Automatic Current Adjustment

The USN1’s actual output current depends on the maximum power supplied from the USB power source. The output current will be adjusted based on the actual power being input to the device. The USN1 is capable of outputting 1000mA, increasing its efficiency while shortening charging duration.

Battery Health Monitoring

Once the battery is inserted, the USN1 will proceed with an initial low current test charge to diagnose the battery status. After the diagnosis, the battery status will be shown as Good, Normal or Poor. Note: Re-insert the battery when “Poor” appears on screen to eliminate the possibility of a poor battery contact, replace the battery if “Poor” comes up on screen consistently.

Reverse Polarity and Anti-Short Circuit Protection

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.

Over Discharged Battery Activation

The USN1 will automatically activate over-discharged battery caused by improper storage or misuse. As for the battery can not be activated, it will be considered as damaged, and “EE EE” will shown on the screen to notify users.
NOTE: this function only available for batteries with a protection board.
