Wireless Charger Induction Multifunctional USB Warm Heating Coaster Cup 350ml Capacity Constant 55°C Temperature High Temperature Strengthened Porcelain Mug with 18W Output and 8 Hour Runtime in Black or White
Wireless USB Mug Warmer with 350ml Porcelain Cup and Constant 55°C Heating for 8 Hours

Maintaining a hot drink while working, gaming, or relaxing often means repeated trips to the microwave or kettle, interrupting your focus. This wireless charging warm cup provides a practical alternative by keeping your beverage at a consistent 55°C – an ideal temperature for comfortable sipping – for a full eight hours. It eliminates the cycle of hot, lukewarm, and cold that plagues standard mugs. The core innovation lies in its induction heating system, which transfers warmth wirelessly through the base of the included porcelain cup. Powered by a standard USB connection, it integrates seamlessly into any desk setup with a computer, power bank, or wall adapter, offering both a beverage warming function and a wireless charging pad for compatible devices.
Features and Construction

The product combines beverage warming technology with device charging convenience in a single, compact unit. Its design is centred on delivering a specific, sustained heat level using efficient induction principles, avoiding the safety concerns of exposed heating elements. The construction prioritises a stable thermal transfer from the base to the cup contents.
Material and Build
The warming vessel is made from high temperature strengthened porcelain, a material chosen for its ability to withstand consistent warming cycles and distribute heat evenly. This contributes to the product's core function of maintaining a stable beverage temperature. The electronic base houses the induction coil and circuitry required for the 18W heating output and manages the power drawn from the 12V/1.5A input. The integration of these components into a unit only 8.5mm thick demonstrates a space-efficient design.
Size and Practical Fit
With an external diameter of 110mm, the warming coaster has a footprint comparable to a standard mug, ensuring it fits easily on crowded desks or bedside tables. The 8.5mm profile keeps it low and stable. The specified 350ml capacity of the porcelain cup indicates it is intended for a substantial single serving of tea, coffee, or other hot drinks. The wireless induction system has an effective transmission distance of 6mm or less, meaning it will work with the provided cup and may accommodate other similar containers of compatible material and thickness placed directly on its surface.
Uses and Placement

This device is tailored for scenarios where a constant hot drink is desired without active management. It moves beyond the basic function of a coaster into the realm of active temperature maintenance. Its USB power requirement makes it highly versatile regarding location, as it doesn't need a dedicated mains socket.
Event or Professional Use
In office environments, it serves as a personal desktop warmer, allowing workers to enjoy a hot drink throughout long meetings or focused work periods without leaving their desk. For reception areas or waiting rooms, it can provide a welcoming touch, keeping a carafe of coffee or tea appetisingly warm for visitors. Its quiet, flameless operation makes it suitable for libraries, study halls, or hotel rooms where open flames or noisy appliances are prohibited. The eight-hour runtime covers a standard workday or an extended event without requiring a recharge or reset.
Everyday Home Use
At home, it becomes a convenient companion for home office workers, gamers, or readers who want to keep a drink hot during long sessions. Placed on a bedside table, it can keep a night-time beverage at a palatable temperature. Its secondary function as a wireless charger (with outputs of 5V/1A, 9V/1.2A, and 12V/1.5A) means it can simultaneously warm a drink and charge a smartphone or wireless earbuds, decluttering the space. The simple requirement of a USB port means it can be powered from a television, gaming console, or power strip.
Benefits and Buying Value

The value proposition rests on combining two common needs – beverage warming and device charging – into one unit, saving space and reducing cable clutter. Its primary benefit is the elimination of cold drinks through automated, sustained heating, which is both a convenience and a contributor to a more pleasant, uninterrupted experience.
Reuse and Low Maintenance
The product is designed for repeated daily use; the porcelain cup is durable and easy to clean with a wipe. The electronic base requires no maintenance other than ensuring the USB port and cable connection remain secure. There are no filters to replace or complex settings to adjust. The specified charging efficiency of ≥75% indicates a focus on power conversion effectiveness, which contributes to lower energy waste during its extended eight-hour operating periods compared to less efficient constant heating methods.
Why Choose This Product
This warmer is distinguished by its specific combination of a large 350ml porcelain cup, a precise 55°C constant temperature setting, and an exceptionally long eight-hour wireless runtime. Many basic warmers offer shorter durations or less capacity. The inclusion of multifunctional wireless charging outputs adds utility beyond just warming. The use of induction heating is a practical differentiator, as it provides warmth without a red-hot visible element, making it safer for use around papers and in homes with children or pets. The product delivers a focused solution based on concrete, measurable specifications rather than vague promises of warmth.
