"MugWarmer II," which combines a mug warmer and a Qi2-compatible wireless charger, is now available!

"MugWarmer II" is a product that combines a mug warmer that keeps drinks hot and a Qi2-compatible wireless charger. Simply place the special mug on the base of the device to wirelessly transmit power, and the ceramic heater built into the bottom of the device keeps the drink warm. The warming temperature can be set in the range of 40-70°C in 1°C increments, and the warming timer and power-off timer can also be adjusted in 1-minute increments. It is also equipped with an anti-burning function and a safety design that automatically turns off after 8 hours.

When not in use as a mug warmer, it can also be used as a Qi2 wireless charger. It can charge Qi2 compatible smartphones at a maximum of 15W by adsorbing them snugly. The device automatically switches to warm mode when the dedicated mug is placed, and to charging mode when a smartphone or earphones are placed, eliminating the need for time-consuming operations.
The dedicated app allows users to turn the power on and off, adjust the temperature, set My Mode, and set the timer from their smartphone. White water, coffee, and soup mode settings are available by default. The inside of the lid is removable and washable, and the waterproof rating IPX6 allows for washing in water and cleaning with mild detergent.
