Overview of Ember 

Ember Mug Review

Long-time coffee-enthusiast and Ember mug founder, Clay Alexander, created his revolutionary mug with the Ammunition Design Group in order to solve a worldwide problem. Hot beverages that turn cold before we can enjoy them are a universal frustration. With a technological solution that Alexander tackled in 2010, he forever changed the way people can consume hot beverages. 

The mug uses precision sensors to keep your beverage at exactly the right temperature by heating it with a dual-band microprocessor-controlled heating system. Get ready for this: you can even control the temperature with your smartphone. Mind blown.

Ember Mug 2 Can Review 

It’s not all about looks, but life can be a bit more enjoyable while surrounded by aesthetically-pleasing objects. The sleek Mug 2 is that kind of object, featuring its own charging stand to keep coffee warm all day if you’re a slow sipper. 

The Mug 2 comes in two colors options. Classic black is a go-to, but this Ember mug review thinks there’s something alluring about the white. Perhaps it’s the clean, neutral look that would pair oh-so-well on top of a wooden office desk.

Getting back to the Mug 2 specs: it keeps your beverage warm for 80-90 minutes depending on size (10oz or 14oz). This attractive, beverage-boosting Mug 2 retails between $100-$130 based on color and size.

Ember Halo Lid Review 

Elevate your coffee experience with the 24k Gold Halo Lid. Along with an enhanced beverage drinking experience, the 24k gold plated lid adds elegance and style to the Ember Travel Mug

Forget unscrewing the lid and drinking from the side of a cup. Halo lids provide opening sipping for when you get to work and no longer need a closed container. The classy 24k Gold Halo Lid retails for $100.

The pretty metallic of the Extra Charging Coaster adds a hint of elegance around your home, or wherever coffee or tea is enjoyed. Keep one at your writing table and another by the bed to enjoy on lazy weekend mornings or afternoons. Available in five colors, the Extra Charging Coaster works with the 10oz or 14oz Ember Mug.

You can mix and match the colors to add some visual interest. We suggest pairing the black mug with the gold coaster for an especially cool contrast. Make your life more convenient with the Extra Charging Coaster for $40

The Ember Mug’s Google rating is taken from various online retailers like Best Buy and Target. Google ranks the brand as 4.5/5 stars from 686 ratings. One 5/5 star review read: “I had never thought that a few degrees in the temperature would actually make my coffee or tea taste better.

By contrast, a customer who rated the Mug 2 at 1-star stated that the battery life steadily decreased within the first 2 months. His review read: “At first they kept coffee at chosen temperature and would charge up in about an hour. Now….they Both are lasting a little less than a half hour….and take about 5-6 hours to recharge.

I bought my Ember mug less than a year ago. The finish came off the bottom of the inside of the cup, and it stopped keeping my drink hot for an hour and a half. Yesterday, it went off after 30 minutes. It’s in the trash.
