Quick guide from the manual

This guide provides essential information for the safe and efficient use of your Xiaomi 120W Fast Charger. Always ensure your device is compatible with fast charging protocols such as USB Power Delivery (PD) or Qualcomm Quick Charge (QC) to utilize the full charging speed. Keep the charger dry, well-ventilated, and away from extreme temperatures.

Important Notes

• Cable Requirements: To achieve 120W charging, you must use a USB-C cable that supports 6A current and includes an E-Mark chip. Standard cables may limit power.
• Device-Limited Speed: The actual charging speed is controlled by your device's battery management system. It will only draw the power it is designed to handle.
• Multiple Devices: When charging multiple devices simultaneously, the total output power is dynamically allocated, which may decrease the maximum speed for a single device.

Troubleshooting

If you encounter issues, check the following:

• Not charging: Ensure all connections at the outlet, charger, and device are secure.
• Charging slowly: This is normal if the device does not support the maximum wattage; the device negotiates the safe maximum power it can accept.
• Overheating: If the charger becomes excessively hot, unplug it immediately, let it cool down in a well-ventilated area, and check for obstructions.
• Incompatible cable: Always use the provided or a certified high-wattage USB-C cable.
