Ember Mug 3 and Tumbler 2 launch with on-mug controls and premium pricing

Ember’s Mug 3 and Tumbler 2 debut with practical upgrades

Ember has unveiled the third iteration of its temperature-controlled smart mug, the Mug 3, alongside a new Tumbler 2. According to TechCrunch, the Mug 3 introduces on-mug temperature controls, allowing users to adjust their drink’s temperature without relying on the Ember app. Five preset temperatures, ranging from 125°F to 145°F, can be cycled through using a button on the bottom of the mug. However, the placement of this button may make it difficult to press when the mug is full of hot liquid.

Pricing, availability, and product details

The Mug 3 is available in two sizes: a 10-ounce version for $129 and a 14-ounce version for $149. The 10-ounce model comes in black, white, and stainless steel, while the 14-ounce version offers eight colors, including sage green, lavender, and powder blue. The mug can maintain the selected temperature for up to three hours on a single charge and is the first in Ember’s lineup to be top-rack dishwasher-safe. It is not, however, microwave-safe.

Ember also launched the Tumbler 2, a 16-ounce tumbler priced at $179, which replaces both the Travel Mug 2 and the original Tumbler. Designed to fit standard car cup holders, it expands Ember’s product range for users on the go. Both the Mug 3 and Tumbler 2 are available for purchase on Ember’s website, Target, and Amazon.

From lukewarm drinks to smart temperature control

Ember first introduced its temperature-controlled smart mug in 2016, targeting the common frustration of drinks losing their ideal temperature. The Mug 3 builds on this concept with incremental improvements, such as a sliding lid designed to prevent spills and reduced reliance on the companion app for basic functions.

While the Ember app has been a staple of the product’s functionality, it has also been a source of frustration for some users due to connectivity or pairing issues, as reported by TechCrunch.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

Ember’s latest product updates reflect a focus on addressing practical pain points for users, such as easier temperature adjustments and improved durability. The on-mug controls are a notable shift, reducing reliance on the app—a common frustration in earlier models. However, the high price point and limitations like non-microwave-safe materials may still give price-sensitive consumers pause. For founders, this launch underscores the importance of iterating on user feedback while balancing premium pricing with perceived value.

Key takeaways

• Ember’s Mug 3 and Tumbler 2 target convenience with on-mug controls and dishwasher-safe designs, but their high cost may limit mass appeal.
• The shift away from app dependency for core functions could set a trend for smart home devices aiming to simplify user experiences.
• Founders should note Ember’s strategy of incremental upgrades—like sliding lids and car-cup-holder compatibility—rather than radical innovation. These small improvements can justify premium pricing in niche markets.
