We tested the OutIn Nano portable espresso machine on the road. Here's our honest review on espresso quality, battery life, and whether it's worth the investment for travelers.

For coffee lovers, the thought of traveling without a decent espresso is almost unbearable. Hotel room coffee, gas station lattes, and airplane brew just don't cut it. That's where portable espresso machines step in, promising café-quality shots anywhere. The OutIn Nano is one of the most talked-about options in this space, and we've taken it on multiple trips to see if it lives up to the hype.

In this review, we'll break down the OutIn Nano's design, performance, battery life, and overall value. We'll also compare it to other portable options and help you decide if it's the right travel companion for your caffeine needs.

Design and Portability

The OutIn Nano is compact, weighing just over a pound and standing about the size of a water bottle. It's designed to slip into a backpack, carry-on, or even a large purse. The sleek exterior is available in several colors, including a vibrant Fuchsia Pink and a nature-inspired Forest Green. The build quality feels solid, with a durable plastic body that can handle the bumps of travel.

One of the standout features is the integrated folding cup and coffee capsule storage. This thoughtful design means you don't need to carry extra accessories. For added protection, you can pair it with the EVA Protective Case Plus, which we found to be a worthwhile investment for keeping the machine safe in checked luggage.

  • Weight: 1.1 lbs (500g) – easily fits in a backpack
  • Size: 9.4 x 3.1 x 2.8 inches – similar to a tall water bottle
  • Integrated cup and capsule storage – no extra accessories needed

Espresso Quality and Performance

The OutIn Nano uses a 20-bar electric pump to extract espresso, which is impressive for a portable device. In our tests, it produced a rich crema and a balanced shot, comparable to what you'd get from a larger home machine. The water temperature is controlled to stay within the optimal range, ensuring consistent extraction.

We tried it with several coffee options, including the Sunrise Blend | Dark Roasted Whole Specialty Coffee Beans and the Guatemala Single Origin- Medium Roast. Both yielded flavorful shots, though we noticed that the grind size needs to be fine enough for best results. The machine uses standard Nespresso capsules, which are widely available, but you can also use reusable capsules with your own ground coffee.

The included foldable cup is a nice touch, but we found it a bit small for a full lungo. However, for a quick espresso shot, it's perfect. The machine also has a pre-infusion function that helps with even extraction.

  • 20-bar pump – professional-grade extraction
  • Pre-infusion mode for balanced flavor
  • Compatible with Nespresso capsules and reusable filters

Battery Life and Charging

The Nano is powered by a built-in rechargeable battery that provides enough energy for about 10-15 shots per charge, depending on the temperature of the water used. It charges via USB-C, which is convenient since most travelers already carry that cable. A full charge takes about 2 hours.

We found the battery life to be sufficient for a weekend trip, but if you're a heavy user, you might need to charge mid-trip. It's worth noting that the machine can also be used while plugged into a power bank, which extends its usability. For longer adventures, we recommend carrying a portable charger.

  • Battery capacity: 1200mAh – good for 10-15 shots
  • Charging time: 2 hours via USB-C
  • Can be used while charging with a power bank

Ease of Use and Cleaning

Using the OutIn Nano is straightforward: fill the water tank, insert a capsule, press the button, and wait for your espresso. The machine heats up in about 20 seconds, which is faster than many larger machines. The one-button operation makes it accessible even for beginners.

Cleaning is also simple. The water tank, drip tray, and capsule container are detachable and can be rinsed under water. We recommend wiping the exterior with a damp cloth. For deeper cleaning, you can run a cycle with just water. The machine does not require descaling as often as larger espresso makers, but it's still a good practice to do it every few months.

  • One-button operation – perfect for travel
  • Detachable parts for easy rinsing
  • No complicated maintenance

Comparison with Other Portable Espresso Makers

When compared to manual lever espresso makers, the OutIn Nano offers more consistency and less effort. Manual devices require you to pump the lever manually, which can be tiring and inconsistent. The Nano's electric pump ensures a uniform pressure every time.

Against other electric portables, the Nano stands out for its integrated cup and capsule storage, which is a unique convenience. However, it's slightly heavier than some ultra-light manual options. For travelers who prioritize ease and consistency, the Nano is a top contender.

We also tested the Nano with the OutIn Foldable Coffee Stand, which makes the setup more stable and comfortable, especially when you're using it on uneven surfaces. The stand is lightweight and folds flat, making it a great companion for camping or outdoor adventures.

Pros and Cons

To help you decide if the OutIn Nano is worth it, here's a quick rundown of its strengths and weaknesses.

Pros: Excellent espresso quality, compact design, integrated cup and capsule storage, fast heat-up time, easy to clean, USB-C charging.

Cons: Battery life could be longer for heavy users, the cup is small for larger drinks, capsules can be expensive over time.

  • Pros: 20-bar pump, pre-infusion, 10-15 shots per charge
  • Cons: Requires fine grind for best results, no milk frother

Final Verdict: Is It Worth It?

After weeks of testing, we can confidently say that the OutIn Nano is one of the best travel espresso machines on the market. It delivers a café-quality shot in a portable package, and the convenience of having an espresso anywhere is a game-changer for coffee enthusiasts.

The only real drawbacks are the battery life and the small cup size, but these are minor when you consider the overall performance. If you're a frequent traveler who refuses to compromise on coffee, the OutIn Nano is definitely worth the investment. It's also a great gift for the coffee lover in your life.

To get the most out of your Nano, we recommend pairing it with the Sunrise Blend | Dark Roasted Whole Specialty Coffee Beans for a rich, bold shot, or the Cold Brew- Medium Roast if you prefer a smoother, less acidic flavor. Both are excellent choices that highlight the machine's capabilities.

In summary, the OutIn Nano portable espresso machine is a worthy travel companion for anyone who takes their coffee seriously. Its combination of portability, performance, and ease of use makes it a standout in its category. While it's not the cheapest option, the quality and convenience justify the price. If you're ready to upgrade your travel coffee game, we highly recommend giving the Nano a try.
