Ember Mug 3: Keep Your Coffee at Your Chosen Temperature

Published November 1, 2026

Ember Mug 3: Keep Your Coffee at Your Chosen Temperature

Coffee gets interrupted. The Ember Mug 3 gives you a way to keep a small morning coffee or afternoon tea at your chosen drinking temperature while you work, read or move through a busy routine. This post features the black 10-ounce model, with its matching charging coaster.

The mug has temperature controls and an LED display on the mug itself, so adjusting your drink does not have to mean reaching for your phone. The included lid is useful when you want to retain heat between sips. It is a temperature-maintaining mug, not a kettle for boiling cold water.

Check the current listing for the 10-ounce black version, included accessories and regional power-adapter requirements. Battery duration depends on your starting drink temperature, temperature setting and lid use. Follow Ember's cleaning instructions and keep the charging coaster dry.
