USB-powered hot and cold coaster with semiconductor cooling for office and home drinks

This versatile coaster provides both heating and refrigeration functions for beverages at your desk or home entertainment area. Operating from standard USB power with DC5V input and 10W consumption, it eliminates the need for dedicated power outlets while offering temperature control for drinks. The TEC semiconductor refrigeration system enables cooling alongside heating capabilities, making it suitable for beer, beverages, juice, coffee, wine, yogurt and similar liquids. With compact 152mm x 31mm dimensions, it fits comfortably in limited spaces without dominating your work surface or side table.

Features and Construction

The coaster combines multiple material components to deliver its temperature control functions while maintaining practical usability. The construction focuses on thermal management alongside durability for regular use with various drink containers.

Material and Build

Constructed from ABS plastic, tempered glass and aluminium components, the coaster balances thermal properties with structural integrity. The ABS plastic housing provides the main framework, while the tempered glass surface offers a smooth, stable platform for drink containers. Aluminium elements contribute to thermal conductivity within the system. This material combination supports both heating and cooling functions while maintaining a clean appearance in either ivory white or noble black colour options.

Size and Practical Fit

Measuring 152mm in diameter and 31mm in height, the coaster maintains compatibility with standard cup and glass sizes while keeping a low profile. The circular design accommodates most beverage containers without excessive overhang, and the 31mm height prevents it from interfering with typical desk arrangements. The dimensions make it suitable for placement between keyboard and monitor setups, on side tables during entertainment, or in kitchen areas where counter space is limited.

Uses and Placement

The coaster serves multiple beverage temperature control needs across different environments, from professional settings to casual home use. Its USB power requirement increases placement flexibility compared to mains-powered alternatives.

Event or Professional Use

For office environments, the coaster provides convenient temperature maintenance for drinks during work hours without requiring kitchen visits. Meeting rooms benefit from keeping coffee warm during extended discussions or chilling water bottles during summer sessions. Event organisers can use multiple units across buffet tables or presentation areas where access to conventional cooling or heating appliances is limited. The semiconductor cooling operates quietly compared to compressor-based systems, making it suitable for environments where noise reduction matters.

Everyday Home Use

In home settings, the coaster serves as a convenient accessory for keeping drinks at preferred temperatures during television viewing, computer work or reading sessions. Gaming setups benefit from having chilled beverages available without leaving the station, while home office workers can maintain coffee temperature during video calls. The unit handles various liquids including beer, beverages, juice, coffee, wine and yogurt, making it versatile across different household preferences and occasions.

Benefits and Buying Value

The coaster offers practical advantages through its dual-function design and USB power compatibility, providing temperature control without specialised installation requirements.

Reuse and Low Maintenance

The construction materials support repeated use with minimal maintenance requirements. The tempered glass surface resists staining from condensation and cleans easily with standard glass cleaning methods. ABS plastic components maintain their appearance through regular wiping, and the aluminium elements do not require special treatment beyond occasional dusting. The USB power connection means no battery replacement or complex electrical maintenance is necessary for continued operation.

Why Choose This Product

This coaster suits users seeking convenient temperature control for drinks without investing in separate heating and cooling devices. The combination of functions in one unit saves space compared to owning dedicated warmers and chillers. USB power compatibility increases placement options where mains sockets are limited or inconveniently located. The semiconductor cooling technology provides refrigeration without the bulk and noise of compressor systems, while the heating function maintains beverages at comfortable drinking temperatures.
