Overview: Outin Nano Review
I’m mad about coffee appliances. I’ve tested countless models, including plenty of portable espresso makers. Lately, I’ve been curiously eyeing the Outin Nano portable espresso machine. The fact that I often go camping and travel the world a lot piqued my interest even more.
When I’m on the road, I often find myself craving a proper espresso. The Outin Nano Portable Espresso Machine, born for good coffee on the go, seems to be ideal for these moments.
Standing 9 inches (23 centimeters) tall, it has a stylish and durable steel body and reassuring leak-proof design. Best of all, this portable electric espresso machine is self-heating. This sets it apart from many portable espresso makers on the market.
While the Nano portable coffee maker is tiny, it’s mighty impressive! It delivers 20-bar pressure — right in the sweet spot for portable espresso extraction. Plus, because this is a one-click-button type deal, making espresso won’t feel like solving a Rubik’s cube.
The versatility here is also worth highlighting. Whether you’re a roast-and-grind-your-own-beans purist or pod devotee, the Nano says, “Why not both?”
Also noteworthy in this Outin Nano review, is its battery capacity. A single charge brews up to five shots from cold water. But the ability to make 200 shots with hot water? Off the charts! In addition, the USB-C charging compatibility means you can power it virtually anywhere. Oh, and the Nano also boasts easy disassembly for washing in less-than-ideal conditions.
So, can this travel-friendly espresso machine yield flavorful espresso with rich crema in only 3-4 minutes? The jury’s out. But at $149.99 with a one-year warranty, I’m curious to explore its capabilities.
Outin Nano Features
Here are some features of the Outin Nano that caught my attention.
Size and Design
The Nano portable electric espresso maker is revolutionary in its size and design. It’s about the size of a water bottle, so it’ll be easy to lug around.
But it isn’t just the size that caught my attention. Its leak-proof outer body and food-grade plastic make a beautiful marriage of style and function. And those measurement markers on the interior of the water tank? Definitely enough for fool-proof brewing action.
Another feature that stands out is the single button interface. It doesn’t get simpler than that. These little touches more than show that the designers understood the assignment.
Colors
Let’s face it; we coffee lovers know that our gear isn’t only about function. It’s also about the daily ritual and style. In this regard, Outin has excelled with Nano’s curated color palette.
Pearl White is perfect for minimalist souls who appreciate clean aesthetics. Then there’s Forest Green, which brings a touch of nature to your coffee routine. Other enticing colors include Space Grey, Teal and the Instagram-worthy Fuchsia Pink.
With these options, you won’t have to compromise between great coffee and beautiful design. Plus, if you’re into giving coffee-inspired gifts, having these options is a real game-changer.
User Interface
Remember those mornings when you can barely string two thoughts together? The Nano gets it. It’s about the coffee, not complicated controls.
Conveniently, pressing its single button activates indicator lights, which update you as you brew. A solid light means it’s heating up, while blinking shows it’s ready to brew. When it goes steady again, it’s done brewing.
Does this simplicity come at the cost of quality? It doesn’t seem to. The Nano packs essential functions into a minimalist interface without compromising quality. In a complicated world, this is UX design at its best.
Brewing Modes
Unlike other portable espresso makers, the Nano boasts two clever brewing modes. It offers the flexibility to brew with hot water or cold water (using the self-heating function). Think of it as two different paths to the perfect espresso.
In essence, Nano claims to brew espresso in 3-4 minutes using cold water. However, while this mode is convenient, it does use up more battery power. One full charge yields only five hot shots.
However, the hot water mode is a game-changer, brewing an impressive 200 shots while conserving battery life. This option is great for off-grid adventures when you know you’ll be away from a power source for a while. Heck, it’s a backup plan for your backup plan!
Battery and Charging
Imagine you’re on a weekend camping trip far from any power outlet. But you still crave that perfect barista-quality espresso. That’s where the Nano portable coffee maker battery capacity comes in.
This small espresso machine comes with three 7500mAH lithium batteries. That’s enough caffeine-fueled freedom to keep you going in the great outdoors. Plus, the USB charger cable is compatible with USB-C charging for car or universal charging. It charges in an impressive 45 minutes from dead.
What I love about this setup is how it eliminates battery anxiety. This is a downside that plagues other portable espresso makers.
Two Ways to Brew
Another must-mention for this Outin Nano review is the two brewing methods. You can brew ground coffee with a pressurized basket, or pop in a compatible coffee pod.
First, let’s talk about the ground coffee option. The pressurized basket extracts flavors from ground coffee without harsh variables in less-than-ideal conditions. This option appeals to purists. Alternatively, during busy mornings or when time is of the essence, opt for pods.
The good thing is Nano is compatible with a wide range of coffee capsules. These include Lavazza, Cafe Royal and the big daddy of them all, Nespresso. Thankfully, this versatility means never having to compromise. Though you’ll never find me using this option (I’ll explain why shortly).
20 Bar Pump
Nano’s 20-bar built-in pump pressure also caught my attention. A real espresso machine operates at 9-bar pressure. This is the sweet spot for espresso extraction. The Nano portable coffee maker boasts an impressive 20-bar pump. And here’s why this matters: the extra pressure ensures you achieve proper extraction in less-than-ideal conditions.
Think about those mornings when your grind isn’t perfect. Or when you’re using a days-old coffee pod.
That’s where this robust pump system shines. It’s powerful enough to push hot water through your coffee with just the right force to extract all those wonderful flavors. And create that gorgeous crema most people love!
Nano Basket Plus
I have to tell you about another impressive feature in this Outin Nano review — Nano Basket Plus. You’ll only find this upgrade on the company’s website. But when you see the add-ons included, you’ll understand why it has coffee enthusiasts buzzing!
Let me break it down for you. At the heart of this portable espresso machine is a premium non-pressurized stainless steel basket that gives you more control over brewing.
This filter basket also doubles shot capacity to 16-18 grams, perfect for those iced lattes, or in the summer, fancy espresso tonics. As someone who occasionally needs that extra kick, this is a game-changer.
Now, here’s what impresses me more. Nano Basket Plus isn’t just a filter basket; it’s a complete brewing upgrade kit. Inside, you’ll find a number of accessories, including a precision WDT tool and a funnel for loading coffee grinds mess-free. Also included is a stylish tamper, which helps you achieve an even extraction every time.
This, in my humble opinion, is what takes the Nano coffee machine from impressive to extraordinary.
How to Use the Outin Nano Portable Espresso Machine
Using this pocket-sized barista is incredibly easy and it’ll have you drinking espresso in no time. First, make sure your Nano portable espresso machine is on full charge. Then, if using coffee grounds:
Remove the plastic cup from the bottom of the espresso machine.
Unscrew the portafilter, then remove the filter basket and lid.
Use the scoop to add 5-6 grams of finely-ground coffee grinds to the basket.
Using the same scoop, tamp your coffee, then replace the lid.
Place the filled basket into the portafilter. Tightly screw the portafilter to the espresso maker and return the bottom-sitting plastic cup.
Now, add water. Lift open the water tank’s top lid and fill it with 1.7 ounces (50 milliliters) of cold filtered water (self-heating function).
Press the button for 2 seconds to heat water; stop pressing as soon as the button beeps. This heating process takes 3-4 minutes. Once hot enough, indicator lights will blink to denote extraction.
Alternatively, you may heat water beforehand, and then pour, preferably using a gooseneck kettle. In this instance, simply double-click the button to begin extraction directly into an espresso glass or cup.
If you’re a pod person (I’m not due to the horrendous effects these have on the environment) there’s a third brewing option. Remove the capsule adapter from the portafilter and place a compatible coffee capsule into it. Then, insert the adapter back into the portafilter. Follow the same brewing steps as for ground coffee above.
Note that, on a full charge, 1.7 ounces (50 milliliters) of cold water per Nespresso pod yields 4-5 cups. In contrast, 2.7 ounces (80 milliliters) per coffee capsule yields slightly less (2-3 cups).
I’d love to see how this portable espresso machine retains heat during extraction. At some point, I’ll put it through its paces alongside my trusted home espresso machine. So, stay tuned for that showdown!
Pro Tips
Use fresh espresso beans roasted within 7-21 days for the best flavor
Brewing with filtered water reduces mineral buildup
Use a good espresso grinder to grind your beans fresh
Pre-heating your espresso cups improves the crema
Outin Nano Cleaning
Clean-up for this Outin Nano review is pretty straightforward. After a brew, let everything cool down, before unscrewing the portafilter and removing used coffee pods or grounds. Fun fact: used grounds make excellent plant fertilizer. Recycle these grounds and dispose of the Nespresso pod responsibly to reduce landfill waste.
Next, give all removable parts a thorough rinse under warm (never boiling) water. Then, wipe the water reservoir and exterior dry before reassembly. Occasionally you may soak removable parts in mild soapy water to remove coffee grounds and oils.
I also recommend regular descaling, especially in hard water areas. You’ll know you need to do so when your coffee tastes “off” or your machine slows down. Consult the manual for instructions.
Pro Tips
Set aside a small brush or toothbrush for cleaning hard-to-reach parts
Avoid harsh cleaning chemicals; they can affect your coffee’s taste
Outin Nano vs WACACO Nanopresso
How does Outin Nano compare against other portable machines? The Nano, all stainless steel and food-grade plastic, exudes a modern, premium feel. It’s also small enough to slip into your pocket.
In contrast, the larger WACACO Nanopresso, sports a rugged, tactical aesthetic. Built primarily from reinforced plastic it has a bomb-proof quality that outdoor enthusiasts will appreciate.
Functionality also reveals their most striking differences. Nano embraces tech and simplicity with self-heating and one-touch fully automatic operation. Despite its size, its built-in pump delivers 20-bar pressure.
Conversely, Nanopresso, with 18-bar pressure, takes a more traditional approach. It’s a manual espresso maker (expect an arm workout) that requires hot water to brew. While this means more effort, it offers you a more hands-on brewing experience.
Both devices’ feature sets also tell an interesting story. The Nano comes with modern conveniences like USB charging and batteries. It also plays nice with ground coffee and Nespresso pods.
Meanwhile, the Nanopresso embraces its manual nature — no power needed, ever. Another similarity is that both devices offer optional kit upgrades that expand their capabilities.
The price points of each further highlight their market positioning. Nano commands a higher price, justifying it with automated features. In contrast, at $67.92 Nanopresso offers a more accessible entry point. However, you might find yourself investing in extra accessories over time with this coffee maker.
So, who wins this showdown? Well, that depends entirely on you. If you value convenience and modern tech, Outin Nano is your bae. However, if you’re an off-grid coffee purist Nanopresso will sing to you. In short, both will have you drinking espresso — they just take very different paths doing it.

Outin Nano Review FAQ
Nespresso, L’OR, Lavazza, Cafe Royal, Jacobs and Kimbo pods are all compatible with Outin Nano espresso makers.
Using the provided USB-C cable, it takes about 45 minutes to completely charge the Outin Nano from dead.
Rinse removable parts and the water tank in warm water then dry. For deep cleaning, hand-wash parts with a sponge and mild detergent, before rinsing and drying. Avoid boiling water as it might cause the body to fade.
