Amazon’s Black Friday deals include record-low prices on Ember self-heating coffee mugs. Typically $ 130, the 10-oz. Ember Smart Mug 2 starts at $ 90. The devices keep your coffee, tea or other heated beverage at an ideal temp and make a perfect gift for coffee lovers. The white, black and red variants are all on sale, but the black and red versions cost $ 100. Only the white model is available for $ 90.

The Ember Smart Mug 2 can heat your coffee between 120 and 145 degrees Fahrenheit, preventing your cozy, warm drink from becoming lukewarm and unpleasant. It has a companion app for Android and iOS that allows you to pick your favorite temp, set it and forget it.

The mug begins heating automatically when it detects liquid and will go to sleep when it’s empty. It lasts up to 80 minutes per charge, but leaving it on its bundled charging coaster means it can last all day, no matter how insatiable your caffeine habit is.

Amazon’s Black Friday sale also includes the larger (14 oz.) Ember Smart Mug 2 for $ 40 off. Other than size, this model has the same features, battery life and temperature range as the 10 oz. version. The white model is available for the sale price of $ 109.46 at the time of publication. Alternatively, the copper metallic model is only $ 129.95, down from its usual $ 180.
