The Ember Mug Warmer

A coffee that stays how you poured it.

The warmer that keeps your own mug hot, however you take it.
A touch-controlled USB mug warmer built with three temperature levels, so a drink stays at the heat you actually want rather than one fixed setting. Made from aluminum alloy and tempered glass, it works with the mug you already own, and switches itself off automatically after 8 hours if anyone forgets.

Key Benefits
• Three temperature levels, touch controlled
• Works with any mug you already own
• 8-hour automatic power-off
• Aluminum alloy and tempered glass build

What It Is
The Ember Mug Warmer is a compact touch-controlled warming coaster built from aluminum alloy and tempered glass, designed to sit under any mug, cup, or glass and keep a hot drink from sliding back toward room temperature. A touch switch cycles between high, medium, and low heat settings, so coffee, tea, or milk can be kept at whichever temperature actually suits the drink.
Powered via USB (DC 5V/2A, 8–10W), it runs quietly from a laptop, power bank, or wall adapter, and includes automatic shutoff after 8 hours of continuous use, so it never needs to be remembered at the end of a long day at a desk.

How It Works
• Touch switch cycles between high, medium, and low temperature settings
• Aluminum alloy and tempered glass construction for even, consistent heating
• USB powered, DC 5V/2A, 8–10W
• Automatic shutoff after 8 hours of continuous operation
• Compact footprint (7 x 102mm) suited to any desk or nightstand

What to Expect
• A drink that stays at your chosen temperature, not just warm
• Three real heat levels, not a single on/off setting
• Quiet, consistent warming from any USB power source
• Automatic shutoff if it’s ever left running
• Compatible with the mug you already reach for daily

Coffee That Doesn’t Go Cold Halfway Through
The specific disappointment of a good coffee going lukewarm before it’s finished is what this exists to solve. The Ember Mug Warmer sits under the mug already on the desk, holding it at a chosen temperature through a full work session rather than letting it fade the moment attention moves elsewhere.

Three Levels, Not One Setting
A single warming temperature rarely suits every drink — tea, coffee, and milk all sit differently at high, medium, or low heat. A simple touch switch moves between all three, so the right level is a quick tap away rather than a compromise everything gets heated to the same degree.

Left Running, Handled Automatically
Forgetting to switch off a desk gadget at the end of a long day is easy to do. The Ember Mug Warmer builds that oversight in as a non-issue — after 8 hours of continuous use, it shuts itself off automatically, no reminder needed.
