A thermostatic heating plate holds your drink at a cozy, even temperature for hours — no more reheating runs to the microwave.

Slim coaster design
A low, minimalist pad that doubles as a coaster and blends into any desk — it earns its tiny footprint every morning.

Questions, answered
How warm does it keep my drink?
It holds your drink at a comfortable, sippable warmth — designed to maintain heat, not boil. It keeps an already-hot drink warm rather than heating a cold one from scratch.
How is it powered?
By USB. For best performance use a 5V/2A USB input (laptop, power bank, or adapter). A 5V/1A port may not supply enough power to keep it warm.
What mugs work on it?
Most flat-bottomed ceramic, glass, and stainless-steel mugs. For the best heat transfer, use a cup with a smooth, flat base that sits fully on the pad.
Can I leave it on while I work?
Yes — it's made for all-day desk use with gentle, stable heat. As with any heating device, switch it off when you leave for the day.
