3. Connecting Power
Connect the provided USB Type-C charging cable to the input port on the back of the BD3 Charging Dock. Connect the other end of the cable to a compatible USB-C power adapter (not included). For optimal performance and fast charging, a 30-100W USB-C charger is recommended.

4. Applying the Anti-Slip Mat
Peel off the protective film from the anti-slip mat and firmly attach it to the bottom surface of the BD3 Charging Dock. This will prevent the dock from sliding on smooth surfaces.
Operating Instructions
1. Charging B100 Batteries
Place up to three B100 battery packs onto the designated magnetic charging interfaces on the dock. The magnetic connection ensures proper alignment and secure charging. The dock can charge all three batteries simultaneously.

2. Fast Charging Capability
Each battery interface provides independent 30W fast charging power. This allows a B100 battery to reach 80% capacity in approximately 1 hour. The total power output of the dock is limited by the connected USB-C charger.

Maintenance
To ensure the longevity and optimal performance of your BD3 Charging Dock:
- Keep the charging contacts clean and free of dust or debris. Use a dry, soft cloth for cleaning.

Troubleshooting
If you encounter issues with your BD3 Charging Dock, consider the following:
