The Ember Smart Mug 2 is a 10 oz stainless-steel mug that keeps coffee at a set temperature between 120 and 145 °F. You pick the temperature in the Ember app, and a built-in battery holds it for roughly 80 minutes on a charge, or all day on the charging coaster. It suits desk workers and slow sippers who hate reheating cold coffee. Against cheaper heated mugs, it adds precise app control and a temperature display, but the battery life is short and the mug is heavy at 14.5 oz.
