The Ember Tumbler 2 is a 16 fl oz temperature-controlled travel mug that holds a drink at a set temperature for hours. It improves on the original with top-rack dishwasher safety, a slimmer body that fits car cupholders, and on-tumbler controls: one to five clicks set 125°F to 145°F without the app. Battery life is about 3+ hours with the lid on, well short of a full workday, so it suits commutes, desk mornings and short trips more than all-day outings. Rivals like the Ember Mug 2 hold temperature longer but are open mugs; the Tumbler 2 trades some runtime for a sealed, portable lid and cupholder fit. Owners rate it highly for build and convenience, with battery life the common complaint.

The Ember Tumbler 2 is a temperature-controlled tumbler that keeps a drink at the temperature you choose. It holds 16 fl oz and has a slim shape made to fit car cupholders.
You can set the temperature in the Ember app or directly on the tumbler, and the app is not required. Pressing the button once to five times selects 125°F, 130°F, 135°F, 140°F or 145°F. Indicator lights show the selected temperature and display the battery level while the tumbler charges on the coaster.
The tumbler is top-rack dishwasher safe. Battery life is 3+ hours with the lid on.
