The Ember Tumbler is a 16 oz stainless steel smart mug that holds coffee at a set temperature between 122°F and 145°F for up to 3 hours via Bluetooth. It ships with two lids: a leak-proof handle lid and a spill-proof sliding lid, and the body is safe to submerge up to 1 meter for cleaning. It is Ember's largest tumbler, with a newer chip for more reliable pairing than earlier Ember mugs. It suits commuters and slow sippers who want an exact drinking temperature, but it costs far more than a plain insulated tumbler and needs charging and an app.
