Outin Nano Portable Espresso Machine

The Outin Nano in Space Grey is a 670 g self-heating espresso machine that pulls 20-bar shots from ground coffee or Nespresso Original capsules wherever you happen to be.

The Nano is Outin's portable espresso machine, here in the understated Space Grey finish. It weighs 670 g, runs on a rechargeable 2,500 mAh battery and heats its own water, so it suits campers, commuters and hotel-room baristas who refuse to settle for instant. Everything it needs, including the cup, screws together into one bottle-sized unit.

The standout is the self-heating system. Pour in cold water, press the button, and roughly 200 seconds later the Nano is at up to 92°C and driving water through your grounds at 20 bar. On a full charge that works up to five times with room-temperature water, or more than 200 shots if you start with hot water.

Ideal for

Campsite espresso

Battery power and a self-heating tank mean no stove, kettle or mains hook-up. Fill it from a flask or bottle and the Nano handles the rest, delivering up to five cold-water brews per charge.

Travel and hotels

At 670 g it disappears into hand luggage, and the USB-C port charges from the same kind of charger as your phone. Hotel kettle water stretches a single charge past 200 shots.

Grounds and capsules

Households split between fresh grounds and Nespresso Original capsules need just one machine. The included adapter takes capsules without piercing, while the filter basket handles espresso-grade grounds with the supplied spoon.

Key features

20 bar pump pressure

The pump drives water through the coffee at up to 20 bar, the pressure behind a dense, syrupy shot topped with proper crema.

Self-heating in 200 seconds

Add room-temperature water and the Nano brings 50 ml up to extraction heat in roughly 200 seconds by itself. No kettle, no stove, no compromise.

Up to 92°C extraction

Water reaches up to 92°C before it touches the coffee, keeping extraction in the range espresso needs rather than the lukewarm middle ground.

2,500 mAh battery

A full charge delivers up to five self-heated brews from cold water, or more than 200 shots when you start with hot water.

2-in-1 brewing

Espresso-grade grounds go in the filter basket; Nespresso Original capsules drop into the included adapter with no piercing required. One machine, both habits.

USB-C and car charging

It recharges over USB-C from a 10 W or stronger charger, and works with 12 V and 24 V car chargers on longer drives.

More to know

Espresso without a kitchen behind it

Most compact espresso makers still need boiling water from somewhere, which quietly ties them to a kitchen. The Nano carries its own heat. Fill the 80 ml tank, press the button and the battery warms 50 ml of cold water to brewing temperature in around 200 seconds, then extracts at 20 bar. That makes the machine genuinely self-contained: water bottle in one hand, Nano in the other, espresso a few minutes later.

Grounds one day, capsules the next

The Nano refuses to pick a side in the grounds-versus-capsules debate. The supplied filter basket takes espresso-grade ground coffee for people who weigh and tamp; the capsule adapter takes Nespresso Original pods, no piercing needed, for the mornings when convenience wins. Swapping between them is a matter of fitting a different holder, so a weekend away can start on freshly ground beans and finish on the emergency capsule stash.

Managing the battery on longer trips

The 2,500 mAh battery is the part worth understanding before you rely on it. Starting from cold water, it will self-heat and pull up to five shots on a full charge, because heating is where the energy goes. Start with hot water from a kettle or flask instead and the same charge stretches past 200 extractions. Recharging happens over USB-C from any 10 W or stronger charger, with Outin recommending a 5 V/3 A plug, and 12 V and 24 V car chargers work too, which suits road trips down to the ground.
