Notice:
1. The actual temperature is affected by the thermal conductivity of the cup and the conditions of use.
2. Automatic power off after 8 hours of work.
3. The product can only be used normally when connected to a charger or power bank with a power of 5V2A(i.e., 10W) or more. It is not recommended to power the computer via the USB interface because the USB interface of a computer only has 5W.
4. This product is suitable for heat preservation. It is not recommended to heat cold water directly. The temperature is approximately 40 to 55 degree centigrade. Any cup can be heated, but it is recommended to choose a flat bottomed one with good heat conduction. The heating power is fixed. The final temperature depends on the usage conditions. The more water there is, the lower the temperature will be; conversely, the lower the temperature will be.
5. When the product is in operation, there is usually a slight current sound, it is normal. This is because the product resonates in a closed space, so the sound is slightly amplified. It does not affect the functional use and poses no safety hazard.
