Can the Minipresso heat up water?

No cannot! Heating up or boiling water requires a lot of energy. With today's technology, there is no battery small and powerful enough to make this solution viable. During a hike, the best way is to bring hot water with you with the help of an isothermal bottle, see our Nanovessel. During camping, you can boil water with a campfire or a gas burner (please be very careful, small blows can often result in catastrophic bush fires). At the hotel, bedrooms are equipped with electric kettles.
