Troubleshooting

Reduced Charging Speed with Multiple Devices

When multiple devices are connected to the power bank, the total available wattage (65W) is distributed among them. This may result in individual devices charging at a slower rate than if they were charged alone. For example, if you plug in a laptop and a smartphone, the 65W output will be shared, potentially reducing the fast charging speed for each device. This is normal behavior for multi-port power banks to ensure stable power delivery across all connected devices.

Device Not Charging or Slow Charging

• Check Cable: Ensure you are using a high-quality, compatible charging cable.
• Power Bank Activation: Press the power button once to ensure the power bank is active.
• Low Current Mode: If charging a small device (e.g., earbuds), ensure Low Current Mode is activated by double-pressing the power button. If a small device is connected while in standard fast-charging mode, it might not charge or charge very slowly due to excessive power delivery.
• Power Bank Charge Level: Ensure the power bank itself has sufficient charge.
