How it works
Fill the water tank with hot or cold water. Insert your chosen coffee - ground or a Nespresso Original compatible capsule - into the coffee chamber. Press the brew button and the machine will automatically heat the water and extract espresso directly into the integrated cup. 

Battery and charging
The built-in 7500 mAh battery powers the heating and extraction system. On a single full charge, the Nano can produce up to about five espresso shots from cold water, or over 200 shots using pre-heated water. Charging can be done via a USB-C cable or through a 12 V/24 V car charger, providing flexible power options when travelling. 

Cleaning and maintenance
The construction allows quick disassembly of the brew chamber and removable parts for rinsing. The electrical and water systems are designed to remain separate for easier cleaning and safe use outdoors. 

Thanks to its combination of automatic water heating, battery power, compact design and support for both ground coffee and capsules, OutIn Nano is ideal for travel, camping, vanlife or everyday use outside the home. It is intended for coffee lovers who want quality espresso anywhere without compromise.
