Key Features:
- Charges up to three batteries in sequence.
- Can be used as a power bank to charge additional devices.
- Intelligent LED indicators for charging status.
- Supports QC and USB PD fast charging.
2. Setup
Connecting the Charging Hub:
- Connect a USB Type-C cable to the 'IN' port on the charging hub.
- Connect the other end of the USB Type-C cable to a compatible power adapter (e.g., a 35W or higher PD/QC3 charger) or power bank.
- Ensure the USB-C cable is fully inserted until a click is heard to establish a secure connection.
Inserting Batteries:
- Align the battery with one of the three battery slots on the charging hub.
- Insert the battery into the slot and press down firmly until a click is heard. This ensures the battery is fully seated and connected.
- The integrated display will show the battery's status once correctly inserted.

3. Operating Instructions
Charging Batteries:
- The charging hub charges up to three batteries in sequence. It prioritizes the battery with the highest charge level first, ensuring you have a ready-to-use battery sooner.
- The hub will deliver up to 18 watts of power to the battery being charged, provided a compatible PD or QC3 charger is used.
- The integrated display shows the charging progress, including voltage, amperage, and percentage charged for each battery.

Using as a Power Bank:
- The charging hub can function as a power bank to charge external USB devices such as smartphones or remote controllers.
- Connect your device to the 'OUT' USB-A port on the charging hub.
- By default, batteries inserted in the hub are charged first. To prioritize charging an external device, press and hold the power button for 2 seconds. This will direct power from the drone batteries to the external device.

Checking Battery Levels:
- With batteries inserted, briefly press the power button on the side of the hub.
- The integrated display will illuminate, showing the current charge level, voltage, and amperage for each inserted battery.
4. Maintenance
Battery Storage Mode:
- The charging hub supports a storage charging mode. If batteries have less than 60% charge, they will be charged to 60-65% for optimal long-term storage.
- If batteries have more than 65% charge, the hub will discharge them to the optimal storage level.
- To activate storage mode, press and hold the power button for 2 seconds when the hub is not connected to an external power source.

General Battery Care:
- Do not store batteries in the charging hub or drone for extended periods. DJI Intelligent Flight Batteries are designed to self-discharge to approximately 70% after a day of non-use to reduce stress on the battery over time. Leaving them in the hub or drone can prevent this self-discharge, potentially leading to battery damage.
- Always ensure batteries are stored at their recommended voltage (around 3.8V per cell for LiPo batteries) for longevity.
5. Troubleshooting
Charging Issues:
- No Charge/Display Reads "0": Ensure batteries are fully inserted into their slots until a click is heard. Also, verify that the USB-C input cable is securely connected to both the hub and the power source.
- Intermittent Charging: If charging is inconsistent, try unplugging and re-plugging the power cable and re-seating the batteries. Ensure your power adapter meets the recommended wattage for stable charging.
- Slow Charging: The hub charges batteries sequentially. If you are using a power adapter with less than 25W output, batteries may charge one by one. For faster charging of multiple batteries simultaneously, use a PD25W+ power source.
