Introduction
The latest version of the company’s temperature-controlled smart mug, the Ember Mug 3, is designed to keep your drink at just the right temperature for as long as you sip.
Ember first introduced its smart mug in 2016 to solve a problem most coffee and tea drinkers know all too well: getting distracted for a few minutes, only to return to a lukewarm drink. Now, the company is back with its third-generation mug, which brings a handful of practical upgrades.
Physical Controls and Design
The biggest change is that you no longer have to open the app to adjust your drink’s temperature. Instead, you can use the button on the bottom of the mug to cycle through five preset temperatures, starting at 125 degrees Fahrenheit. Each press raises the temperature by five degrees, up to a maximum of 145 degrees, so you can easily make your drink a little hotter with each click.
Being able to adjust my drink without getting up to find a smartphone is a small convenience, but one that is genuinely appreciated during extended use.
It’s also a welcome change for users who have reported running into connectivity or pairing issues with the Ember mobile app.
That said, the button is located on the bottom of the mug. It’s a peculiar design choice when you’re dealing with a cup full of hot liquid, and it isn’t particularly easy to press, either.
App Integration and Features
If you prefer using your phone, the Ember app still offers plenty of customization. After pairing the mug with your phone over Bluetooth, you can choose presets based on what you’re drinking. Ember recommends 136 degrees Fahrenheit for black coffee, 132 degrees for green tea, and 142 degrees for lemon water.

Hardware Upgrades
The Mug 3 also comes with a sliding lid designed to help prevent spills. The mug can keep your drink at its desired temperature for up to three hours on a single charge. And it’s the first mug in Ember’s lineup to be top-rack dishwasher-safe, making cleanup easier.
Pricing and Availability
The Ember Mug 3 comes in two sizes: a 10-ounce model for $129 and a 14-ounce version for $149.
The smaller mug is available in black, white, and stainless steel, while the larger size comes in eight colors, including sage green, lavender, powder blue, salt blue, sandstone, white, black, and matcha green.
Alongside the new mug, Ember also introduced the Tumbler 2, which replaces both the Travel Mug 2 and the original Tumbler in its lineup. The 16-ounce tumbler features a slimmer, taller design intended to fit standard car cup holders.
The products are available to purchase on Ember’s website, Target, and Amazon.
