Coffee is what gets many of us through the workday, and a proper smart mug can keep it hot for hours so you can maintain your focus without constantly getting up to reheat your cup. Thankfully, if you don’t own one, the 14-ounce Ember Mug 2 is now available for $97.49 ($52 off) from Amazon, Target, and Ember as part of Ember’s ongoing Mother’s Day sale. You can also buy the smaller 10-ounce model for $84.47 ($46 off) from the same retailers (Amazon, Target, Ember).

Using the Ember app, the Mug 2 lets you set an exact drinking temperature between 120 and 145 degrees Fahrenheit, which it can maintain for up to 90 minutes or all day using the included charging coaster. You don’t have to worry about the battery draining unnecessarily, either, thanks to an automatic sleep function, which powers down the smart mug when it’s empty or hasn’t been used for several hours.
The smart mug offers a fair amount of control beyond that, too. Within the Android / iOS app, you can also create and save preset temperatures for different beverages and set up notifications for when your drink reaches your preferred temperature. Meanwhile, a customizable LED indicator on the coaster lets you quickly check heating and battery status at a glance.
As a bonus, the Ember Mug 2 is also relatively easy to care for. It features a scratch-resistant coating to help prevent wear over time and carries an IPX7 water-resistance rating, so it can be safely hand-washed (just don’t put it in the dishwasher).
