A travel coffee maker is so compact and lightweight that you can take it almost anywhere. To achieve the pressure necessary for filtering an espresso, which is about 16 to 18 bar, it is equipped with a pump that works similarly to a bicycle pump. After pumping, you pour hot water from a kettle or thermos into the water tank, press the button, and let the aromatic coffee flow into your drinking cup. This way, you can enjoy your favorite beverage on the go, whether on trips, hikes, or during breaks between training sessions in sports.
