USB-Powered Hot and Cold Coaster with TEC Semiconductor Technology for Home and Office Use

This versatile temperature control coaster provides both heating and cooling functions for your beverages through advanced TEC semiconductor refrigeration technology. Operating on simple USB power at just 10W consumption, it offers convenient temperature management for various drinks including coffee, beer, juice, wine, and yogurt. Measuring 152mm by 31mm, the coaster fits comfortably on most desks and surfaces while maintaining stability for your drink containers. Available in two sophisticated colour options—ivory white and noble black—it combines practical functionality with subtle styling suitable for both home and professional environments.

Features and Construction

The hot and cold coaster incorporates multiple materials and technologies designed specifically for efficient temperature control and user convenience.

Material and Build

Constructed from three primary materials, this coaster achieves both durability and effective thermal performance. ABS plastic forms the structural housing, providing impact resistance and light weight. The contact surface utilises tempered glass, offering heat resistance and easy cleaning while providing direct thermal transfer to your beverage container. Aluminium components within the construction enhance heat conduction efficiency, working with the TEC semiconductor system to rapidly adjust temperatures according to your needs.

Size and Practical Fit

Measuring 152mm by 31mm, this coaster provides sufficient surface area to accommodate most standard drink containers including mugs, glasses, and cans. The compact dimensions ensure it fits conveniently on crowded desks, coffee tables, or office workstations without occupying excessive space. The height of 31mm allows for adequate internal component housing while maintaining a low profile that doesn't interfere with typical drink pouring or handling.

Uses and Placement

The hot and cold coaster serves multiple beverage scenarios across different environments, from casual home use to professional office settings.

Event or Professional Use

In office environments or during professional gatherings, this coaster maintains coffee at ideal drinking temperature throughout meetings or extended work sessions. The USB power compatibility means it can connect directly to computers, power banks, or standard USB adapters commonly found in workplace settings. For wine enthusiasts, it can maintain red wines at slightly below room temperature or keep white wines properly chilled during social events or tastings.

Everyday Home Use

At home, the coaster provides convenient temperature control for morning coffee, afternoon tea, or evening beverages without requiring trips to the kitchen microwave or refrigerator. Its compatibility with various drink types—from breakfast juice to post-dinner wine—makes it suitable for different household members throughout the day. The simple USB operation means no specialised installation is required, making it immediately usable in living rooms, bedrooms, or home offices.

Benefits and Buying Value

This product offers practical advantages through its dual-function capability and straightforward operation, providing value through convenience and versatility.

Reuse and Low Maintenance

The hot and cold coaster represents a reusable alternative to disposable cooling sleeves or heating pads, reducing waste while providing consistent performance. The tempered glass surface requires only simple wiping to clean, and the ABS plastic housing resists staining from typical beverage spills. With no complex mechanical parts beyond the TEC semiconductor system, maintenance involves basic care rather than specialised servicing.

Why Choose This Product

This coaster combines heating and cooling functions in a single compact device, eliminating the need for separate warming plates and cooling mats. The TEC semiconductor technology provides more precise temperature control than passive solutions while consuming minimal power at just 10W. Its USB compatibility ensures it works with common power sources already available in most environments, requiring no specialised electrical outlets or adapters beyond what users typically possess.
