So plan on only doing this if it’s on the charging coaster. But it can! It just requires some patience (it can take between 30 minutes and an hour), and it will drain the battery. I have been surprised, and a little bit delighted, at the ridiculousness and the wonderfulness of the Ember Mug.Īccording to the manufacturer, the Ember Mug is not designed to heat cold liquids.

But even if you’re enjoying your coffee outside on a cold day, you can expect about an hour of toasty warm java. The 10-ounce version of the Ember Mug will keep your drink hot for up to 90 minutes, while the 14-ounce model gets 80 minutes.įactors that influence longer battery life include the external temperature and the desired coffee temperature. The Ember Temperature Control Mug has a powerful lithium-ion battery that performs as advertised.

The charging coaster is as sleek and subtle as the mug itself, and you need only set the mug on the coaster to start charging. It would be nice to see a USB charging option, which we’ll possibly see in future product iterations. But be prepared to shell out an extra $40 just for an aesthetic upgrade.Įvery Ember Mug comes with a charging coaster plugging into a wall outlet. These gorgeous, smart mugs, labeled the Metallic Series, would make a fantastic gift for that friend or family member who has everything – and loves coffee gadgets. The Ember Mug is also offered in metallic gold, copper, rose gold, and stainless steel. Not only is this a fun way to customize your mug, but if there’s more than one Ember Mug in your home or office, it makes it easy to tell them apart.

The only sign that it’s a smart coffee mug is the subtle LED light at the base, which communicates its status. It’s available in three matte colors – white, black, and gray – and 10-ounce or 14-ounce size. It looks like a standard coffee mug, albeit a fancy one.
