This is a rechargeable self-heating mug that holds a set temperature for up to 12 hours and shows the current temperature on a built-in LED display. You pick one of four heat levels and can change it, and check battery, from a phone app. It suits desk workers, students and commuters who sip slowly and want the last mouthful as warm as the first. Against passive vacuum mugs, which only slow cooling, it actively reheats, but it adds weight, charging and an app to the routine.
