The 20-bar pump then extracts through your ground coffee or Nespresso Original-format capsule, producing an espresso shot with a proper crema layer - no manual pumping, no access to a plug socket required. 2-in-1 Brewer for ground coffee and Nespresso capsules: The included ground coffee filter takes 5 to 8 g of your preferred ground espresso, while the capsule adapter accepts Nespresso Original-format pods from brands including Nespresso, L'OR, Jacobs, Lavazza, Kimbo, and Café Royal. Switching between formats takes seconds, giving you flexibility depending on what you have to hand. Built for travel, camping, and car use: At 230 mm tall and 670 g, the Nano slips into a bag pocket, backpack, or car door compartment without taking up significant space. The USB-C port accepts any charger of 10 W or higher, and the 12 V / 24 V car-charger compatibility means you can top up the battery on the move. The Optimised Battery Management System maximises charge efficiency, and the Double Layer Heat Insulation design keeps the outer casing safe to handle throughout the brew cycle. One-Key Operation and auto shut-off: A single button press initiates the full self-heating and extraction cycle, and the machine shuts off automatically once the brew is complete. The IPX4 waterproof rating means minor splashes and damp outdoor conditions are not a concern during use.
