3. Understanding the Display: The digital LED display shows the exact remaining battery percentage.

Operating Instructions

Charging Devices

The power bank offers multiple options for charging your devices:

• Integrated USB-C Cables: Utilize the two built-in USB-C cables for direct connection to compatible devices. One cable supports 30W input and 45W output, while the other provides 45W output.
• USB-C Port: Use an external USB-C cable with the dedicated USB-C port for up to 30W input and 45W output.
• USB-A Port: Use an external USB-A cable with the USB-A port for up to 33W output.

You can charge up to four devices simultaneously using a combination of the integrated cables and ports.

This diagram illustrates the power bank's versatile connectivity, featuring two integrated USB-C cables (one for 30W input/45W output, one for 45W output), an additional USB-C port (30W input/45W output), and a USB-A port (33W output), allowing for multiple device charging.

Recharging the Power Bank

To recharge the power bank, connect a power adapter to the USB-C input port or the integrated USB-C cable that supports input. The power bank supports up to 30W input for faster recharging.

Low-Current Mode

For charging low-power devices such as earbuds or smartwatches, double-click the power button to activate the energy-saving (low-current) mode. This mode ensures stable and safe charging for sensitive electronics.

Maintenance

• General Care: Keep the power bank dry and away from extreme temperatures. Avoid dropping or subjecting it to strong impacts.
• Cleaning: Use a soft, dry cloth to clean the exterior of the power bank. Do not use liquid cleaners or solvents.
• Cable Durability: The integrated USB-C cables are designed for durability, tested to withstand over 10,000 bends. However, avoid excessive force or sharp angles when using them.

Troubleshooting

• Power Bank Stops Charging at 30%: If the power bank stops delivering power while the display still shows around 30% charge, this may occur during 45W fast charging. Try using the low-current mode or a slower charging method for consistent power delivery. Recalibrating the battery (full discharge then full recharge) may also help.
• Overheating During Fast Charge: When utilizing the full 45W fast charging capability, the power bank may generate noticeable heat. This is normal for high-power delivery but can slightly reduce efficiency. Ensure adequate ventilation.
• Device Not Charging:
  • Ensure the power bank has sufficient charge.
  • Check that all cables are securely connected to both the power bank and the device.
  • Verify that your device is compatible with the power bank's output ports and charging protocols.
  • Try a different cable or port.
