Many people assume that a portable coffee maker can’t truly deliver a rich espresso experience, especially when it’s compact enough to fit in your bag. But I found that’s not always the case with the obecilc Portable Coffee Maker.

The moment I saw it in action, I was surprised how quickly it heats water to 185°F in just four minutes—almost as fast as my kitchen machine.

What really stood out is how seamless it is to use. One tap, and you can brew espresso with ground coffee, Starbucks pods, or Nespresso capsules.

The self-heating feature combined with 20Bar pressure makes a noticeable difference—rich flavor, and that signature creamy crema, just like from a café.

It’s super portable, with a rechargeable 7500mAh battery that lets you make up to 50 shots with cold water or 25 with hot water. Charging via USB-C is convenient, especially on the go, whether from your car or power bank.

I also appreciate how straightforward the one-button operation is—no complicated settings, just press and enjoy.

Of course, it’s not perfect. The small water capacity means you’ll need to refill more often.

And it’s limited to certain capsules, so if you’re a Vertuo or K-Kup fan, this might not be for you. Still, for quick, quality espresso in your hotel room, camping trip, or during a commute, it works surprisingly well.

All in all, this little device challenges the misconception that portable coffee makers can’t match the flavor of bigger machines. It’s a smart choice if you want convenience without sacrificing taste, even if it’s not designed for high-volume brewing.

The moment I pressed the one-button start on the OutIn Nano, I was instantly impressed by how quickly it heated up. Within just 200 seconds, 1.7oz of room temperature water reached nearly boiling, ready to brew a fresh espresso.

That speed makes it perfect for mornings when every minute counts or when you’re on the go.

The compact size is a game-changer. Weighing only 670 grams, it’s easy to toss into a bag or backpack without feeling weighed down.

The stainless steel body feels sturdy yet lightweight, and the removable parts make cleaning a breeze—no fuss, no mess.

I tested both ground coffee and capsules, and both worked flawlessly. The 20-bar pressure delivered a rich, velvety crema that rivals high-end machines.

Whether you’re in a hotel, camping, or just need a quick shot at the office, this little device impresses with its quality and convenience.

Battery life is surprisingly strong. The three 2500mAh batteries support multiple shots, and charging with any USB-C car charger is simple.

Plus, the leak-proof design means no worries about spills or messes—ideal for travel.

One small snag—it’s not suitable for use during flights, so plan accordingly. But overall, the OutIn Nano hits a perfect balance between portability, ease of use, and quality espresso.

It’s like having a barista in your pocket, ready whenever you need that caffeine boost.

Using it was a breeze—just fill, seal, and press the button. I did make sure the sealing ring was correctly in place and checked my capsules, which is key for a smooth brew.

It’s really convenient for travel, camping, or even quick office coffee. The only downside?

The small water capacity means frequent refills on long trips, but that’s expected with its portable size.
