Self-Heating Technology - heats cold water to 92°C in 200 seconds 20 bar pressure for proper espresso extraction Built-in 7,500 mAh rechargeable battery - no mains power needed Up to 5 cold water brews or 200+ hot water brews per charge Works with ground coffee and Nespresso-compatible capsules Weighs just 670 g - fits in a bag or jacket pocket Charges via USB-C - compatible with car (12V/24V) or USB adapter 80 ml water chamber; optimal extraction at 50 ml Food-grade stainless steel water chamber Compact build: 230 mm tall, 70 mm wide Manufacturer warranty: 1 year Dimensions: 230 x 70 x 70 mm OutIn Nano - a portable espresso machine with Self-Heating Technology and 20 Bar Pressure Self-heating espresso wherever you are: The OutIn Nano uses Self-Heating Technology to bring cold water up to 92°C without any external heat source, plug socket, or gas burner. From cold tap water to extraction-ready temperature takes around 200 seconds - that is just over three minutes - making it a genuinely self-contained brewing unit for travel, camping, the car, or the office. 20 bar extraction pressure: At 20 bar, the Nano delivers the kind of pressure associated with proper espresso extraction rather than simply pressing hot water through coffee grounds. The 80 ml water chamber holds enough for a standard espresso shot, with the manufacturer recommending 50 ml as the optimal extraction volume for best results. 2-in-1 compatibility: The Nano works with both ground coffee using the included filter basket and Nespresso-compatible capsules via the included adapter, so there is no need to buy proprietary pods. Switching between formats takes seconds, making it straightforward to use at home before packing it for a trip. Long battery life and USB-C charging: The 7,500 mAh built-in battery delivers over 200 hot water brews per charge, or up to 5 brews starting from cold water. Charging is via USB-C and the machine accepts both standard USB adapters and 12V/24V car chargers, so topping it up on a road trip or at a campsite is straightforward. A minimum 15 W charger output is recommended for proper charging. Built for travel: At 670 g and 230 mm tall, the Nano is designed to fit into a travel bag alongside everything else. The water chamber uses food-grade stainless steel construction throughout, and a Double Layer Heat Insulation Design helps maintain brew temperature during extraction.

Fill the water chamber to the 80 ml mark and select either the ground coffee filter basket or the Nespresso capsule adapter depending on your preferred format. Brewing tips: The manufacturer recommends 50 ml as the optimal extraction volume for best espresso results. Allow the machine to complete its heating cycle - around 200 seconds from cold water - before triggering extraction to ensure the water re the correct brewing temperature of 92°C. Charging guidance: The Nano cannot be used while charging, so plan charging time accordingly. For the fastest recharge, use a USB-C adapter with at least 15 W output. The machine is compatible with both standard USB wall chargers and 12V/24V in-car chargers, keeping it easy to charge on the move. Cleaning and storage: Rinse the water chamber and filter basket with clean water after each use. The
