A ceramic travel mug that holds your set temperature for up to 6 hours — no reheating, no cold sips, no cord on your desk.
The 11:42am problem
By the second meeting it's lukewarm. By the third, it's coffee-flavored water. You either drink it cold or microwave it into something bitter. Neither feels like the cup you actually wanted.
Tap the base once to choose 130°F, 140°F, or 145°F — or hold for precise control in between.
A ceramic heating core keeps your drink locked at that exact temperature, not slowly drifting back down.
Up to 6 hours on a charge. Top up on the included USB-C coaster between refills.
Hold any temperature between 104°F and 145°F — not a vague "warm" setting.
A full charge gets you through a workday, a flight, or a long work-from-home morning.
Charges on a slim USB-C coaster. Lift it off and it keeps holding temperature, untethered.
Nothing but ceramic touches your drink — no plastic aftertaste, no metallic edge.

"I didn't think I needed this until my third meeting of the day, when my coffee was still exactly how I poured it."
"The temperature lock actually works. I set 140 and it stays at 140, not '140 for ten minutes then declining.'"
"Bought one for myself, then two more as gifts. The charging coaster is genuinely well thought out."
