Although referred to as travel hotplate, I'm probably not the only one who bought this unit to an entirely different purpose, namely as a coffee percolator. And there is really perfect. Compared with the unsatisfactory solution to put the espresso pot on far too great a hotplate, which in addition to the waste of energy in the long run harm also the cooker, you save with the mini hot plate not only energy, but the cooking process is also much faster. Actually amazing that there is hardly a competitor to the (however still sold under other brand names) plate Rommelsbacher given the popularity of coffee-makers.
