What’s in the Box? ౼ Unboxing Your Ember Mug
Upon opening your Ember Mug packaging, you’ll find several key components. First, the Ember Mug itself, carefully protected within molded packaging. Alongside the mug, you’ll discover the Charging Coaster, essential for wirelessly powering and maintaining your mug’s temperature.

A USB charging cable is included to power the charging coaster. You should also find a Quick Start Guide providing initial setup instructions. Carefully inspect all items to ensure everything is present and undamaged. Retain the original packaging for potential warranty claims or returns. The Ember Mug is designed for a seamless unboxing experience, preparing you to enjoy perfectly heated beverages immediately.
Understanding the Mug’s Components
The Ember Mug comprises several integrated parts working in harmony. The core is the Mug Body, constructed with a durable, food-grade stainless steel interior and a protective coating. Beneath the mug is the Charging Coaster, which provides wireless power and displays the mug’s status.
Crucially, the mug features LED Indicator Lights, communicating heating status and connectivity. These lights offer vital feedback on the mug’s operation. Internally, a sophisticated heating system maintains your desired temperature. Understanding these components is key to maximizing your Ember Mug experience and ensuring optimal performance.
Mug Body & Coating
The Ember Mug’s body is crafted from high-quality, food-grade 304 stainless steel, ensuring durability and preventing flavor transfer. This material maintains temperature consistency and resists corrosion. The exterior boasts a durable polymer coating, providing a comfortable grip and protecting against scratches.
This coating is heat-resistant, but avoid abrasive cleaners. Carefully note that while robust, the coating isn’t impervious to damage from extreme impacts. Regular cleaning with a soft cloth is recommended to preserve its appearance and functionality; The design prioritizes both thermal performance and user experience.
Charging Coaster Functionality
The charging coaster is integral to the Ember Mug experience, providing both power and a convenient resting place. It utilizes inductive charging, meaning no physical connectors are needed – simply place the mug on the coaster. The coaster’s surface is designed to maintain a secure connection for efficient charging;
Importantly, the coaster isn’t just for charging; it also keeps your mug at your desired temperature when the mug is placed on it. Ensure the coaster is connected to a power source for continuous temperature maintenance. Avoid placing metallic objects between the mug and coaster, as this can interfere with charging.
LED Indicator Lights ౼ Decoding the Signals
The Ember Mug features LED indicator lights at the base, communicating crucial information about its status. A pulsating white light signifies the mug is heating up to your set temperature. Once a solid white light appears, your beverage has reached the desired warmth and is being maintained.
A blinking red light indicates a potential issue, such as a low battery or a connection problem. If the light is off when the mug is on the coaster, verify the power connection. Understanding these signals allows for quick troubleshooting and ensures optimal mug performance. Refer to the app for detailed explanations;
Initial Setup & Pairing with the Ember App

To unlock the full potential of your Ember Mug, download the Ember app (available on iOS and Android). Ensure Bluetooth is enabled on your smartphone. Place your mug on the charging coaster to power it on. The app will automatically detect your mug; select it from the list of available devices.
Follow the on-screen prompts to create an account or log in. The pairing process establishes a connection, allowing temperature control and customization. Without the app, advanced features are inaccessible. Successful pairing is indicated by a change in the mug’s LED status within the app.
Powering On/Off & Basic Operation
Your Ember Mug activates automatically when placed on its charging coaster. To manually power on, press and hold the power button located on the mug’s base for approximately three seconds. The LED will illuminate, indicating it’s active. To power off, repeat this process – a three-second press and hold of the power button.
Once on, the mug maintains your pre-set temperature. Basic operation involves simply filling the mug with your beverage and enjoying. Remember, accessing advanced features like temperature adjustments requires pairing with the Ember app. The mug will enter sleep mode when empty.
Temperature Control ⎼ Using the App
The Ember app unlocks precise temperature control for your mug. After pairing, the app displays the current beverage temperature and allows adjustments between 120°F and 145°F (49°C – 63°C). Simply use the slider within the app to select your desired warmth.
The app also facilitates creating and saving temperature presets for different drinks – coffee, tea, or hot chocolate, for example. Customization extends to naming these presets for quick access. Without the app, the mug operates at a default temperature, but full control requires the connected experience.
Setting Your Preferred Temperature
Within the Ember app, setting your ideal temperature is straightforward. After connecting your mug, navigate to the temperature control screen. A slider allows you to precisely select your desired warmth, ranging from a gentle 120°F (49°C) to a comforting 145°F (63°C).
The app displays the selected temperature in both Fahrenheit and Celsius. Adjust the slider incrementally until you reach your perfect setting. Remember, the mug will maintain this temperature for an extended period, ensuring every sip is just right. Experiment to find what suits your beverage and personal preference best!
Temperature Presets & Customization
The Ember app offers pre-set temperature options for common beverages like coffee, tea, and hot chocolate, providing a quick starting point. However, the true power lies in customization! You can create and save multiple temperature profiles tailored to your specific drinks and preferences.

Name each profile descriptively – “Dark Roast,” “Green Tea,” or “Mom’s Cocoa” – for easy selection. This feature eliminates the need to readjust the temperature every time you switch beverages. Enjoy consistent warmth, perfectly suited to each drink, with personalized presets!
Charging Your Ember Mug
Maintaining optimal battery life is crucial for enjoying your Ember Mug’s temperature control features. The mug charges wirelessly via the included charging coaster. Ensure the mug is properly seated on the coaster for efficient charging – a magnetic alignment assists with this.
A full charge typically takes approximately 1.5 to 2 hours, providing several hours of temperature-controlled enjoyment. Battery life varies based on temperature settings and usage. Leaving the mug on the coaster continuously keeps it at your desired temperature indefinitely, bypassing battery reliance.
Charging Coaster Placement & Usage
For optimal charging, place the charging coaster on a stable, flat surface. Avoid placing it near water sources or in direct sunlight. Ensure the mug is centered on the coaster; magnetic alignment will assist with proper positioning.

The coaster’s LED indicator will illuminate to confirm a connection. A solid light generally indicates charging, while a flashing light may signal an error. Continuously leaving your Ember Mug on the coaster maintains your set temperature without draining the mug’s battery. Avoid using the coaster with damaged cables or power adapters.
Charging Time & Battery Life Expectations

A full charge from empty typically takes approximately 1.5 to 2 hours using the included charging coaster. Battery life varies based on temperature settings and usage patterns. Generally, expect around 1.5 hours of battery life when maintaining a consistent temperature.

Leaving the mug on the charging coaster bypasses battery usage, keeping your beverage at the desired warmth indefinitely. Note: Higher temperature settings will naturally reduce battery longevity. Regularly charging your Ember Mug optimizes its performance and extends the overall battery lifespan.
Cleaning & Maintenance
To ensure optimal performance and longevity, hand wash your Ember Mug with warm, soapy water after each use. Do not place the mug in a dishwasher, as this can damage the internal electronics and coating. The charging coaster can be wiped clean with a damp cloth.
Avoid using abrasive cleaners or scouring pads, as they may scratch the mug’s surface. Ensure the charging contacts on both the mug and coaster are clean and dry before each charge. Regular, gentle cleaning will maintain your Ember Mug’s pristine condition and functionality.
