The Functionality of the Ember Tumbler


The Ember Tumbler is equipped with an internal heating system that aims to keep your beverage at the optimal temperature. By default, it maintains a temperature of 135 degrees Fahrenheit. However, with the help of the Ember app, which allows you to connect the Tumbler to your phone via Bluetooth, you can customize the temperature to suit your preferences.


The Benefits of the Ember Tumbler


The Ember Tumbler offers several advantages. With a capacity of 16 ounces, it holds a substantial amount of liquid, making it suitable for those who prefer larger servings. The Tumbler also comes with two lids: one with a sliding mouthpiece for easy sipping and another with a handle for complete closure. Its sleek design and solid construction provide a luxurious feel when holding the mug, enhancing the overall drinking experience.


For those working from home or spending extended periods indoors, the Tumbler excels at maintaining your drink’s temperature. Placing the Tumbler on its charging pad ensures that your coffee remains hot for hours, even if you step away momentarily. This feature is particularly convenient for individuals who often find themselves engrossed in tasks or distractions.

Heat Retention Comparison: The Ember Tumbler vs. the Yeti Rambler


To assess the Ember Tumbler’s performance as a travel mug, we conducted a series of tests comparing it to the Yeti Rambler. The results revealed some notable differences:


Test Yeti Rambler Temperature (after 1 hour) Ember Tumbler Temperature (after 1 hour)
Control (Start Temp) 205.9°F 204.6°F
I made coffee… 180.7°F 149.4°F
Early morning… 162.7°F 139.2°F
Warm drink… 144.1°F 135.1°F
After four hours 135.0°F 113.7°F


The data demonstrates that the Yeti Rambler outperforms the Ember Tumbler in terms of heat retention. While the Tumbler initially achieves the desired drinking temperature, it loses heat more rapidly than the Rambler. As a result, if you are looking for a travel mug that can keep your coffee hot for an extended period, the Rambler is a more suitable choice.The 3 Mug Warmers We Love for Keeping Our Coffee (and Tea) Hot | Reviews by  Wirecutter




In conclusion, the Ember Tumbler offers an innovative solution for individuals seeking a high-tech travel mug that can maintain their desired drink temperature. With its internal heating system and customizable settings, it ensures a delightful coffee-drinking experience. However, it is important to note that the Tumbler’s heat retention capabilities are not as robust as some other travel mugs on the market.


For those primarily using the mug at home or in a controlled environment, the Ember Tumbler is a worthy investment. Its ability to keep your beverage hot for hours while you focus on your tasks is commendable. However, if you prioritize heat retention during travel or extended periods away from a charging source, the Yeti Rambler, priced at just $30, is a more cost-effective and efficient choice.


Ultimately, the decision between the Ember Tumbler and the Yeti Rambler depends on your specific needs and preferences. Consider your daily routine, travel requirements, and desired heat retention when selecting the perfect travel mug to accompany you on your coffee adventures.
