Ember’s temperature-controlled smart mug is down to one of its best prices

Ever been racing to meet a deadline only to realize your coffee’s gone cold again? The Ember Mug 2 self-heating smart mug keeps your drink hot so you can stay focused without making constant trips to the microwave. And right now, Amazon, Best Buy, and Walmart are selling the 14-ounce smart mug in select colors starting at $103.99 ($46 off) an all-time low of $89.99 ($60 off).

A Verge favorite, the self-heating smart mug keeps your coffee, tea, or cocoa at the perfect temperature from the first sip to the last. With the Ember app (available on Android and iOS), you can dial in your ideal temp between 125 degrees and 145 degrees Fahrenheit and even save presets for your go-to drinks. The built-in battery keeps your beverage warm for up to 80 minutes on a single charge, or you can use the included charging coaster to keep it hot all day. Its smart sleep mode also helps conserve battery by automatically turning off the heat when the mug is empty or hasn’t been moved for a while.

As a bonus, an LED light lets you quickly check charging and temperature status, and you can even customize its color for a personal touch. The Ember Mug 2 is also durable enough for everyday use, with scratch-resistant coating and an IPX7 water-resistance rating so it can safely be hand-washed. Just keep in mind that it’s not dishwasher safe.
