Frequently Asked Questions

Can this coaster boil a cold cup of water or coffee?
No, the thermostatic warmer is designed to maintain the temperature of hot liquids (around 50°C to 55°C) and prevent them from cooling down, rather than heat cold beverages from scratch.

What kind of mugs work best on the heating pad?
Flat-bottomed ceramic mugs, glass cups, and thin-walled stainless steel containers provide the best thermal contact for fast and even warming.

Is it safe to leave plugged in while at work?
Yes, it is built with low-power, energy-efficient components designed for safe continuous desk use. However, always unplug the unit when leaving your home or office for extended periods.
