Safety Information

  • The center of the mug warmer is the heating area. The surface temperature is high during operation and may retain heat after use. Please avoid touching it to prevent burns.
  • Using a non-flat-bottomed or double-layered cup will affect heating and warming performance. For optimal performance, select a mug with a flat bottom and thin walls to ensure a secure connection to the mug warmer.
  • If ceramic cups or plastic cups are used, the heating time and temperature may not reach the expected results.
  • Before cleaning, disconnect the power and allow it to cool down. This product should not be exposed to water or cleaned in water. It is recommended to wipe it with a damp cloth.
  • Please unplug the power cord or turn it off when during cleaning or not in use.
  • Keep the product out of reach of children to avoid burns from high temperatures.
  • If the power cord is damaged, it must be replaced by a professional technician to avoid potential hazards. In case of any malfunction, immediately disconnect the power and stop using the product. Please do not attempt to repair it yourself for your own safety.

Troubleshooting

  • Device not turning on: Ensure the power cord is securely plugged into a working outlet. Rotate the knob clockwise to turn on.
  • Beverage not heating sufficiently: Check that you are using a flat-bottomed, thin-walled mug. Ensure the mug is centered on the heating panel. Adjust to a higher temperature setting if desired.
