Performance

Self-Heating and Crema Quality

The OutIn Nano is equipped with a self-heating mechanism that heats 1.7oz of 77°F room temperature water to a steaming 198°F within 200 seconds. This heating time ensures you don’t have to wait long for your coffee fix. The machine uses a 20-bar pressure pump, which is often found in professional espresso machines, ensuring that each shot has a rich crema—something that sets the OutIn Nano apart from other portable espresso makers.

The self-heating function is a significant selling point. However, there are some mixed reviews regarding how consistently the machine heats the water. While most users report that the water reaches a satisfactory temperature, there have been instances where the water did not heat up properly. This could be an issue with specific units or charging methods, but it’s worth considering before purchasing.

Battery Life and Charging

The OutIn Nano boasts a 7500mAh battery, which is one of its most impressive features. It supports up to five hot shots using 1.7oz of 77°F water, or 200+ shots with hot water. The machine is compatible with USB-C car chargers, making it easy to charge in your car, RV, or on the go. The charging speed is good, and the inclusion of the 5V3A USB cable ensures a more efficient charge compared to standard USB cables.

That said, the battery life is where the reviews start to diverge. Some users report that the battery holds up well for multiple uses, while others find that it drains faster than expected, especially if you’re using the machine in colder conditions. If you’re traveling for long periods without access to charging, this might be a factor to consider.

Ease of Use

One of the key selling points of the OutIn Nano is its one-button operation. With just a single click, you can brew a perfect espresso shot in about 3-4 minutes. This ease of use makes the OutIn Nano an ideal choice for those who want a hassle-free espresso experience without needing to learn complex controls or techniques.

The versatility of the machine is another standout feature. It is compatible with both ground coffee and NS capsules, so you can enjoy your espresso regardless of your preferred method of brewing. The machine has been tested with hundreds of capsule designs, ensuring broad compatibility.

Portability

The OutIn Nano weighs just 1.48 pounds and is compact in size, making it an excellent choice for travel. Its space gray color and sleek design also contribute to its modern, stylish appearance. The machine’s compactness doesn’t compromise its quality or functionality, making it a solid contender for those who prioritize portability without sacrificing performance.
