The Nuvia Haven is a 12oz stainless steel mug with a built-in 4000mAh battery that holds a hot drink at a set temperature instead of letting it cool. A touch-sensitive LED display shows the drink's temperature and controls heating, and it charges over USB-C. It maintains heat rather than reheating, so you pour in hot coffee and it stays warm for roughly 2 to 5 hours. It suits desk workers and commuters who sip slowly; against rivals like the Ember Mug it is a simpler, lower-feature take with a narrower temperature range and no app control.

This 12 oz self-heating coffee mug has a built-in rechargeable lithium-ion battery that keeps a hot drink warm. The body is stainless steel. It works for coffee, tea, hot chocolate and other hot beverages.
A touch-sensitive LED display shows the drink's current temperature. One tap controls the heating. The mug is cordless and charges through a USB-C port from a laptop, wall adapter, power bank or other USB-C power source.
The mug maintains the temperature of a drink that is already hot. It is not meant to reheat a drink from room temperature, which significantly reduces battery life. Battery life depends on usage and ambient temperature.
