Wireless Charging Warm Cup maintains drinks at 55℃ while charging devices with induction heating technology

This innovative dual-function device combines beverage warming with wireless charging capabilities in a single 110mm diameter coaster. Using induction heating technology, it keeps drinks at a constant 55℃ temperature for extended periods, ideal for office desks, home offices, or gaming setups where hot beverages tend to cool too quickly. The high temperature strengthened porcelain construction ensures durability while the 350ml capacity accommod standard mug sizes. Simultaneously, the same unit serves as a wireless charging pad for Qi-enabled smartphones and devices, providing practical utility without occupying additional space. With 18W output power and ≥75% charging efficiency, it delivers reliable performance whether maintaining beverage temperature or charging electronics.
Features and Construction

The wireless charging warm cup employs advanced induction heating technology to maintain consistent temperatures while serving as a charging platform. This dual-function design eliminates the need for separate warming and charging devices, conserving desk space and reducing cable clutter.
Material and Build
Constructed from high temperature strengthened porcelain, the cup provides thermal resistance necessary for beverage containment while offering durability against repeated heating cycles. The material choice ensures heat is evenly distributed throughout the 350ml capacity, maintaining consistent temperature without hot spots. Electronic components for induction heating are integrated beneath the porcelain surface, enabling wireless temperature maintenance while allowing the same surface to function as a charging pad for Qi-enabled devices.
Size and Practical Fit
With a diameter of 110mm and thickness of 8.5mm, the coaster design fits standard desk spaces while providing sufficient surface area for both beverage containment and device charging. The ≤6mm transmission distance ensures efficient power transfer whether heating drinks or charging smartphones. The 1000mm included USB cable provides flexibility in positioning relative to power sources, while multiple charging outputs (5V/1A, 9V/1.2A, 12V/1.5A) ensure compatibility with various devices.
Uses and Placement

The wireless charging warm cup serves multiple functions across different environments, from professional settings to home use. Its constant temperature maintenance and charging capabilities make it suitable for various scenarios where both beverage warmth and device charging are desired.
Event or Professional Use
In office environments, meetings, or conferences, the device maintains coffee or tea at drinkable temperatures throughout lengthy sessions while simultaneously charging smartphones or tablets. The 8-hour continuous operation ensures all-day functionality without interruption, and the black or white colour options allow matching with office decor. Professionals can benefit from reduced interruptions for beverage reheating while keeping devices charged for communication and productivity tasks.
Everyday Home Use
For home offices, gaming setups, or living spaces, the warm cup provides convenient beverage temperature maintenance during extended computer use. Gamers can enjoy warm drinks during long sessions without leaving their stations, while remote workers benefit from consistent temperatures during video calls or focused work periods. The wireless charging function eliminates cable clutter on desks while ensuring devices remain charged for personal or family use throughout the day.
Benefits and Buying Value

The dual-function design of the wireless charging warm cup offers practical advantages through space efficiency and utility consolidation. By combining beverage warming with device charging, it reduces the need for multiple separate devices while providing consistent performance in both functions.
Reuse and Low Maintenance
The high temperature strengthened porcelain construction allows repeated use without degradation, and the induction heating technology provides consistent performance over time. With simple cleaning using a damp cloth when cool, the device requires minimal maintenance while offering continuous service. The included components (USB cable and manual) provide everything needed for immediate use without additional purchases.
Why Choose This Product
This product consolidates two common needs—beverage temperature maintenance and device charging—into a single unit that saves space and reduces cable clutter. The 55℃ constant temperature ensures drinks remain at ideal drinking warmth without overheating, while the 18W output provides efficient charging for compatible devices. With black or white colour options, it offers aesthetic flexibility for different environments while delivering practical functionality for various user scenarios.
