There appears to be a bit of an arms race brewing in the temperature-regulating mug sphere. While companies like Zojirushi, Thermos, and Yeti have all come out with products offering hours-long temperature stability, they aren’t able to increase a beverage’s temperature should it drop below the desired level. This would require some sort of battery power and has been the almost exclusive purview of the Ember mug. (I’ve made my feeling known about the Ember, we don’t need to go over them again.)

But a new combatant has entered the arena. Enter the Cauldryn Coffee Pro, a battery-powered temperature controlling mug touting a long battery life, wide range of temperature settings, and the ability to boil water on demand.

The 16oz Cauldryn Coffee Pro has all the hallmarks of the new-fangled electronic coffee mug, including temperature control, an app to pair with your smartphone via Bluetooth, an LCD display on the mug, and of course a charging base. And per Cauldryn, the Coffee Pro has made some significant improvements over its predecessor the Ember Travel Mug. For one, the Coffee Pro touts a 10-hour battery life, over three times that of Ember’s, as well as a much wider range of temperature settings. Whereas the Ember can hold a beverage between 120°F and 145°F, the Coffee Pro has an expanded range, between 55°F and 190°F.

But the biggest addition is the Cauldryn Coffee Pro’s ability to boil water, which was also, per Cauldryn, the biggest hurdle. After eight months of design and testing, they finally created a mug that was able to heat water to 212°F in 18 minutes. More than just keeping your drink really, really undrinkably hot, providing on-demand hot water opens up a world of brewing options that may not otherwise exist. You can now use the same mug you drink out of to heat the water to make your on-the-go pour-over or French press.

Available in black and white, the Cauldryn Coffee Pro is available for purchase via the Cauldryn website for $149 and includes the 16-ounce travel mug, heating element, battery, desk base, power cord, and lid.

I have to admit, even as an analog person (I enjoy seeing how coffee changes as it cools and don’t see the need for every part of my life to have an app), I’m warming up to the idea of the temperature-regulating mug. There have definitely been times on day trips to the great outdoors where this would have come in handy. Maybe it won’t be my go-to—because again, I need another I have to regularly charge like I need a thumb growing out of my back—but if the Cauldryn can live up to the hype, it may have made me a sometimes, in the right circumstances believer in the battery powered coffee mug.
