Ember’s Mug 2 and Travel Mug 2 extend your coffee temperature sweet spot – TechCrunch


One of the world’s most static technologies may be the humble mug, but startup Ember decided it was time for a change when they introduced their temperature-controlled smart mug to the market in 2016. Now, the company has launched its Ember Mug 2 — a follow-up that keeps the concept and design intact, but that improves the lineup in some key ways.

There are two separate new second-generation Ember mugs — the Ember Travel Mug and the Ember Mug, designed for home and office use. Both add extended battery life, thanks to swapping its old battery technology with “the most advanced battery technology on the market,” and both gain new redesigned charging coasters, while the Travel Mug 2 gets a new control interface for adjusting the temperature of the beverage within, and it’s a bit lighter while holding the same volume.

Ember Mug and Travel Mug 2 3This sequel to Ember’s home mug comes in black, white and a pricier copper version, as well as in two sizes: 10 oz and 14 oz. Like its predecessor, it features an internal heating element and battery, Bluetooth connectivity for smartphone control from the Ember app and a durable ceramic coating.

The Ember Mug 2 has a customizable LED that shows you when it’s working, and that you can change to whatever color you wish, which is handy if you have a couple of these in use in one household. In order to set your desired temperature, you pair it with an app on your phone (a quick and painless process).

Ember will send you notifications when the liquid within reaches the desired temperature. I’ve long used one of their first-generation products, and the one thing I found was that on my three-a-day coffee schedule, sometimes my third cup would end up cold, because the battery, while decent, would run out before my appetite for caffeine did.

Enter the sequel, which offers up to 50% better battery life than the original version. It’s hard to quantify, as the speed with which I drink my coffee differs day to day, but I will say that in testing I haven’t seen the low battery warning before I was long done…
