Operating Instructions

This product is designed specifically for Sony NP-FZl00 camera battery. It 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.

Charging Modes

The USN4 Pro has 2 charging modes (QC Mode and Standard Mode).
QC Mode: The USN4 Pro is QC 2.0 available. When connecting to a QC supported device (or adaptor), the display will show “Quick Charge” on the upper left corner. In this status (Input Voltage: 9V), it can charge 2 batteries simultaneously with a max output current of 800mA in either slot, or 1 battery with a max output current of 1,200mA.
Standard Mode: In this status (Input Voltage: SV), it will charge the battery which is put in first with a max output current of l,000mA, and then charge the other when the first battery is fully charged.

Automatic Current Adjustment

The USN4 Pro’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 inputted to the device, increasing its efficiency while shortening charging duration.

Battery Health Monitoring

Once the battery is inserted, the USN4 Pro 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 USN4 Pro 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 USN4 Pro will automatically activate over discharged battery caused by improper storage or misuse.
NOTE: this function only available for !batteries with protective circuit.
