OutIn Nano Portable Electric Espresso Machine - Electric Coffee Grinder, Silicone Mat, Compact Travel Espresso Maker with 15 Bars Pressure, USB-C Rechargeable

Product Overview

The OutIn Nano set combines three components: an espresso machine, a coffee grinder, and a silicone mat. The espresso maker has a 1.7-ounce capacity, compatible with Nespresso Original pods or ground coffee via a basket (implied by its operation mode). It operates on battery power, making it truly portable. The grinder uses a 38mm heptagonal burr made from 420 stainless steel with a hardness of HRC 55-60, rated to handle up to 100 kilograms of beans. Its 28-position grind dial allows precise adjustments in a single turn. The silicone mat withstands temperatures from -20°C to 150°C and protects surfaces from spills and heat. The entire set weighs under 1.5 pounds and comes in a sleek black finish. Cleaning involves disassembling the removable parts and rinsing them with water. The grinder is also easy to clean, with a brush included (though not explicitly stated, typical for such grinders). This system is ideal for users who want to brew espresso anywhere without sacrificing quality, but its small water tank means single-shot brewing only.

Build & Materials

The OutIn Nano espresso machine is constructed from food-grade stainless steel, ensuring durability and resistance to corrosion. The outer casing blends sustainable materials, keeping weight low while maintaining rigidity. The grinder features a 38mm heptagonal burr made from 420 stainless steel hardened to HRC 55-60, which delivers consistent particle size and longevity. The included silicone mat is heat-resistant and protects surfaces from spills and thermal damage.

The machine is designed for easy disassembly: the water tank, portafilter, and drip tray can be removed for thorough cleaning. The grinder's burr is accessible for brushing out coffee residue. All components are visually clean and modern, with a matte black finish that resists fingerprints. The build quality feels solid despite the lightweight construction, though the small capacity (1.7 ounces) means it is best suited for single shots. The set's compact footprint fits easily in a suitcase or office drawer.

Shot Quality

According to the manufacturer, the OutIn Nano's 20-bar pump generates sufficient pressure to produce espresso with a thick, golden crema. The self-heating system brings water to the optimal extraction temperature of 198°F within 200 seconds, a feature that eliminates the need for preheating or external hot water. The grinder's 28 settings allow fine adjustments to match bean type and roast level. With the heptagonal burr, grind consistency is reportedly high, reducing channeling and improving flavor extraction.

Because the machine uses Nespresso Original pods as well as ground coffee, users have flexibility. The small water tank limits output to one shot at a time but ensures freshness. Battery operation means no cord restrictions, though runtime and recharge time are not specified. Real-world performance likely varies based on grind size, tamping pressure, and water quality. Without published reviews, these claims should be taken as stated by OutIn. The kit's ability to deliver hot, well-extracted espresso in a portable form is its primary value proposition.
