The Best Portable Espresso Makers: 4 Compared (and One to Skip)
We compared four portable espresso makers on pressure, basket size, heating, coffee compatibility and what each maker publishes.
The short version
The Wacaco Picopresso is the pick: a 52 mm stainless basket that takes an 18 g double dose, a naked portafilter, up to 18 bar by hand, a full accessory kit in a case, 350 g and a 2-year warranty. The Staresso SP200 Classic is the value buy, an electricity-free maker with up to 20 bar that takes both ground coffee and capsules, though Staresso publishes few other specs. The OutIn Nano suits travelers without a kettle, heating 50 ml of room-temperature water in about 200 seconds on its 2,500mAh battery, but that battery covers only about five brews from cold water. Skip the 2026 Staresso Mini: the new version takes Nespresso Original capsules only, not ground coffee, and pulls a small single cup. Best for: travelers, campers and office espresso drinkers.

Portable espresso makers promise a real shot anywhere, from a hotel room to a campsite. Most are hand-pumped and need you to bring hot water; a few heat the water themselves on a battery. The biggest differences are whether they take ground coffee, capsules or both, how big the dose is, and how much you have to learn to get a good shot. We compared two manual makers, a battery-powered self-heating one and a capsule-only travel model.

How we judged the field
Five things decide how good a portable espresso maker is in practice. Coffee compatibility comes first: ground coffee, capsules or both. Dose and basket size decide whether you get a proper double shot. Heating decides whether you need to carry hot water. Weight and size matter because the whole point is to travel with it. And the amount of skill required decides whether you’ll actually enjoy using it.
The field splits into manual makers that need hot water, battery makers that heat it, and small capsule-only travel models. We picked the Wacaco Picopresso, the Staresso SP200 Classic, the OutIn Nano and the 2026 Staresso Mini. Every spec below comes from the maker’s own product page, and where a figure isn’t published, we say so.
The Wacaco Picopresso is the pick for anyone who wants the most café-like shot from a portable maker. Its key feature is a wide 52 mm stainless steel basket that takes an 18 g double dose, paired with a naked portafilter so you can watch the extraction. Wacaco rates it at up to 18 bar by hand, with 80 ml of water capacity, and it weighs 350 g at 71 x 78 x 106 mm. The kit is complete: a double basket, tamper, scoop, brush, distribution tool, funnel and protective case, backed by a 2-year warranty. The catch is that it asks something of you. It doesn’t heat water, Wacaco recommends an ultra-fine grind, which usually means a good grinder, and dialing in grind, tamp and pumping takes practice. For people who enjoy that process, it is the one to buy.
The Staresso SP200 Classic is the value pick because it is cheap and flexible. It works with both ground coffee and capsules, needs no electricity, and Staresso rates it at up to 20 bar using a segmented pressure design. The pump, tank liner and powder cup are stainless steel, and Staresso says it brews in about one to two minutes. You’ll need hot water from a kettle or flask. The drawback is how little Staresso publishes: there is no dose size, water capacity, weight or warranty term on the product page, so it’s harder to compare directly with the Picopresso. For budget buyers who want to switch between pre-ground coffee and pods, it is a sensible buy.
The OutIn Nano solves the biggest hassle of portable espresso: finding hot water. It heats 50 ml of room-temperature water in about 200 seconds, according to OutIn’s own lab testing, reaching up to 92°C, and pushes it through at up to 20 bar. It takes ground coffee or Nespresso Original capsules with an adapter, holds 50 to 80 ml of water, weighs 670 g and charges over USB (above 10W) or a 12V/24V car charger. The limitation is the battery. OutIn quotes up to five brews per charge when heating from room temperature, though over 200 when you add hot water. It is the heaviest and most expensive maker here, and OutIn says to carry it in cabin baggage only. For campers and travelers without a kettle, it is worth it; if you usually have hot water, a manual maker is lighter and cheaper.
The Staresso Mini, sold as the Travel NS, is a tiny, electricity-free maker with a stainless steel build and a 15 to 20 bar pump. The problem is the 2026 version. Staresso states it is only compatible with Nespresso Original capsules, not ground coffee, while older versions under the same name took both. That makes listings confusing and limits you to pods. It also makes one small cup of about 35 ml at a time. For a little more, the Staresso SP200 Classic takes both grounds and capsules. Unless you only drink capsules and want the smallest maker possible, skip it.
Wacaco Picopresso vs Staresso SP200 Classic Portable Espresso Maker: which should you buy?
The Picopresso and the SP200 Classic are both hand-pumped and need hot water, but they aim at different drinkers. The Picopresso is built for ground coffee only, with a 52 mm basket, an 18 g double dose, a naked portafilter and a full accessory kit, and it rewards careful grinding and technique. The SP200 takes ground coffee or capsules, costs less, and asks less of you, but Staresso publishes far fewer specs.
Choose the Picopresso if you grind fresh beans, care about shot quality and enjoy the process. Choose the SP200 if you want convenience, use pre-ground coffee or capsules, or are buying a first portable maker on a budget. If you often lack hot water, the OutIn Nano is the one that solves that.
What to look for
- Coffee compatibility: check whether it takes ground coffee, capsules or both, and which capsule type.
- Dose and basket size: a larger basket, like 52 mm with 18 g, allows a real double shot.
- Heating: manual makers need hot water; battery models heat it but use a lot of charge doing so.
- Weight: under half a kilogram is easy to carry; heavier models trade weight for features.
- Included accessories: a tamper, funnel and case save extra purchases.
- Version changes: check the current version’s specs, since some makers change compatibility between years.
Our final take
For espresso lovers who travel, the Wacaco Picopresso is the maker to buy: a 52 mm basket, an 18 g double dose, a full kit and a 2-year warranty. If you want something cheaper that takes grounds or capsules, the Staresso SP200 Classic is a flexible value. The OutIn Nano is the one to choose if you often have no hot water, as long as a handful of cold-water brews per charge is enough. The 2026 Staresso Mini takes capsules only, which makes it hard to recommend.
Questions, answered
Do portable espresso makers make real espresso?
The better ones get close. Espresso needs finely ground coffee pushed through by pressure, and makers like the Picopresso, rated at 18 bar, can produce a thick, concentrated shot. Results depend heavily on grind size, dose and water temperature. Capsule-based makers are more consistent but limit you to pods.
Do I need a grinder?
For the best results with ground coffee, yes. Wacaco recommends an ultra-fine grind for the Picopresso, which most pre-ground coffee isn't. A good hand grinder travels well. If you don't want to grind, a maker that takes capsules is easier.
Does a portable espresso maker heat the water?
Most don't. The Picopresso and both Staresso makers need hot water from a kettle or flask. Battery models like the OutIn Nano heat water themselves, though heating from cold uses a lot of battery; OutIn quotes about five brews per charge that way.
Can I take a portable espresso maker on a plane?
Manual makers without batteries are simple to pack. Battery-powered models follow airline rules for lithium batteries, and OutIn says to carry the Nano in cabin baggage only and not use it during the flight. Check your airline before you fly.
What does bar pressure mean?
Bar is a unit of pressure; one bar is roughly atmospheric pressure at sea level. Espresso is commonly brewed around 9 bar in café machines. Portable makers often quote higher maximums like 18 or 20 bar, but the shot quality depends more on grind, dose and technique than the peak figure.
