As a coffee lover who’s always on the go, finding a portable espresso maker that doesn’t compromise on quality has always been a challenge. Let me introduce you OutIn Nano Portable Espresso Machine—a compact, rechargeable device designed to deliver café-quality espresso wherever you are. After testing it both indoors and outdoors, I’m excited to share my thoughts and experiences with this amazing gadget.
About OutIn Nano
The machine supports both Nespresso-compatible capsules and ground coffee, giving you flexibility in your brews. It also features a water tank with an 80ml capacity, perfect for a single, rich shot of espresso.
Key Features and Specifications
The OutIn Nano stands out with its impressive features:
• Compact Design: Lightweight at 670g, making it perfect for travel and outdoor adventures.
• Powerful Battery: A 7,500mAh lithium battery that brews up to 5 cups of espresso on a single charge using cold water or significantly more with hot water.
• Compatibility: Works with both Nespresso-compatible capsules and ground coffee.
• Quick Heating: Brews within minutes, depending on water temperature.
• Barista-Level Quality: Produces rich crema and smooth espresso.
Testing the OutIn Nano
Cold Water Brewing
For my first test, I used tap water at 13°C and filled the tank to its maximum capacity of 80ml. After loading a Colombian coffee capsule from Starbucks, I pressed the button to start brewing. The process took about 6 minutes, as the machine had to heat the cold water. Once it beeped, the brewing began, and the result was fantastic—rich, creamy espresso with a strong yet smooth taste.
Hot Water Brewing
Next, I tested the machine with boiling hot water. The brewing started almost instantly, cutting out the heating time entirely. This is a game-changer if you have access to hot water, as it saves time and conserves battery life. The coffee was just as rich and smooth as before, and I appreciated how quickly it brewed.
Outdoor Brewing Experience
Taking the OutIn Nano outdoors was a treat. On a cold and windy day, I set up an outdoor table and brewed espresso using cold water. The process took slightly longer due to the temperature, but the machine performed flawlessly. Watching light steam rise as the water heated was a satisfying moment, and the resulting espresso was just as good as when brewed indoors.
Enjoying a barista-level coffee experience in the middle of nature felt like pure luxury.
Limitations and Areas for Improvement
While the OutIn Nano excels in many areas, there are a few limitations:
1. Pass-Through Charging: The machine doesn’t support brewing while plugged in. This means you’ll need to recharge it fully before use if the battery runs out. Adding pass-through charging would be a great feature for future models, especially for emergencies or extended outdoor use.
2. Cold Water Brewing Time: While the machine performs well, brewing with cold water takes around 5–6 minutes, which might feel long if you’re in a rush. Using hot water helps overcome this limitation.
Final Verdict
The OutIn Nano Portable Espresso Machine is an incredible gadget for anyone who loves coffee and values portability. Whether you’re traveling, camping, or simply looking for a compact coffee maker for home use, this device delivers consistent, high-quality espresso with minimal effort.
Despite minor limitations like the lack of pass-through charging, the machine’s portability, versatility, and great coffee quality make it a standout option in the portable coffee maker market.
