Making Barista Quality Espresso Available In Any Location!
Check on Kickstarter
Welcome! We are COFFEEJACK 🙂
We’ve developed a groundbreaking gear powered extraction method that allows you to create consistent, premium-grade espresso effortlessly—whether you’re at home or outdoors—all at an affordable price.
Most coffee shops use espresso as the base for a variety of drinks like Americanos, Lattes, Flat Whites, and Iced Coffees. However, making a good espresso is no easy task—it requires high pressure during the extraction process, which is why espresso machines are typically large, expensive, and not very portable. This can be a problem for coffee lovers, especially when they’re in locations without a good coffee shop or don’t want to spend thousands on a high-end machine for their home. That’s where COFFEEJACK V2 comes in!
We’ve made premium espresso accessible anywhere, thanks to our innovative planetary gear technology!
While portable, COFFEEJACK V2 is primarily designed for its exceptional build quality and the ability to create premium-grade espresso. It is crafted with a deep understanding of the science behind great espresso, ensuring it replicates the quality you’d expect from expensive high-end commercial machines. But its a fraction of the size and cost!
We took COFFEEJACK V2 to Extract Coffee Roasters in Bristol to carry out some testing! FYI: Their blends are absolutely INCREDIBLE!
Our previous projects have been featured by:
For most, COFFEEJACK V2 replaces the need for a large, expensive, non-portable espresso machine at home. This not only saves money, but saves worktop space as COFFEEJACK V2 can easily be stored in a cupboard or carried in a rucksack for your next adventure!
COFFEEJACK V2 features a durable all-metal body with stainless steel food contact components, ensuring long-lasting use. It extracts a double shot (18g) of fresh espresso using a 54mm unpressurised portafilter, eliminating the need for pods, making it an eco-friendly choice for premium espresso. We’ve chosen lightweight aluminum for components that aren’t exposed to water, prioritising both durability and ease of travel.
So, do portable espresso machines already exist? Yes…but they have a few common problems.
Most have issues regarding shot consistency, robustness, heat retention and ease of use. They do not truly replace a professional espresso machine and therefore many people either still invest in a home machine or buy take out coffee. Both of these options are expensive.
COFFEEJACK V2 is able to produce constant high pressure, essential for making barista quality espresso. Our focus is quality of espresso extraction over anything else.
COFFEEJACK V2 uses a High Torque Planetary Gearbox to easily reach 9+ Bar pressure required for quality espresso by converting hand powered rotation into linear piston motion. This offers full pressure profile control much like a commercial grade/lever espresso machine, but it’s a fraction of the size and doesn’t require a flat surface to operate!
Many other products have claims of reaching ‘high pressure’ but fail to explain how the pressure is ‘controlled’ throughout the extraction which is most important. Imagine buying an oven that can reach the right temperature to bake a cake, but it can’t maintain that temperature as you bake. That cake wouldn’t turn out right—and in the same way, a coffee machine that can’t maintain the right pressure will never give you the perfect espresso!
So, are there other PORTABLE espresso machines that offer constant pressure control? Yes, lever machines but they have some disadvantages:
1. Most require assembly before and after use/complicated workflow.
2. Require a flat surface to operate
3. Many require substantial input force
4. Not as portable
5. Heavier than COFFEEJACK V2
COFFEEJACK V2 has all the benefits of a constant pressure lever machine, in a compact design that doesn’t require a flat surface/component setup AND produces 9+ Bar using low input force.
After all, there is nothing worse than struggling with complicated coffee maker parts, wasting time, and missing out on the simple pleasure of enjoying a great cup of coffee with friends.
One tap, DONE!
COFFEEJACK V2 is incredibly easy to clean, producing dry pucks that pop out effortlessly with minimal mess. This means you can get ready for your next extraction in no time!
Pressure control is crucial, but how it’s applied to the coffee grounds is even more important. Most machines use small exit apertures for the water chamber, causing uneven water flow and ‘channeling,’ which leads to poor extraction and bad-tasting coffee. Plus, the erratic flow results in significant heat loss.
COFFEEJACK V2 solves this with a full-width aperture, ensuring even water distribution across the coffee grounds. This creates a balanced, rich coffee with minimal heat loss, allowing for a optimised extraction and sensational taste!
Whilst it may appear unusual, this is why the COFFEEJACK V2 water chamber is filled by placing the machine upside down. This not only makes preheating quick and easy, but it means no exit valve is required. No exit valve means water distribution is the full width of the portafilter and heat loss is reduced!
COFFEEJACK Can then be used with a stand (available before shipping) or with a tumbler.
Elevation Stand: Enables use with a variety of glasses/mugs (mostly for home use). Many enjoy using the stand as the extraction can be easily viewed and adjustments can be made for optimal espresso shot quality.
Tumbler: Simply attach to the bottom of COFFEEJACK V2 and extract directly into the tumbler. This means COFFEEJACK V2 can be used without the need for a surface and the double wall insulated tumbler keeps drinks hotter for longer!
But thats not all!
The water is then filtered through a professional-grade shower screen, typically used for Barista competitions. This process evenly further distributes the water, ensuring it’s perfectly prepared to create a fantastic espresso before reaching the coffee grounds!
The COFFEEJACK V2 lets you extract espresso with or without a stand. Simply attach the stainless steel insulated tumbler, and you’re good to go! This design is ideal for use in environments without flat surfaces, while also preserving heat throughout the extraction process—ensuring minimal heat loss from machine to cup.
COFFEEJACK V2 is designed for simplicity whilst also offering a professional level of extraction control. There is no assembly, no hassle, just an opportunity to enjoy your espresso and savour the moment.
COFFEEJACK V2 Portable Espresso Machine is very portable!
- There is no electricity required for the extraction process as it is all achieved by hand! This means you wont be affected by limited battery life!
- Its very small (8.4cm x 13cm)
- Lightweight (approx. 1kg)
Its the perfect little machine to pop in a rucksack for your next adventure!
We flew out to Budapest to meet Miklos (Co-owner of Pressensor). Having talked for months about COFFEEJACK V2, it was great to actually meet in person and refine this exciting upgrade option.
This innovative technology is not only crafted in the heart of Budapest, but it has also undergone rigorous testing by a well-established electronics company with years of experience.

Our prototypes are produced by the same factory who will be mass manufacturing COFFEEJACK V2. This ensures that we understand the tolerances/finishes before we start manufacture.
We have worked with this factory for a number of years and they are exceptional! They are an expensive option for us, but for good reason! Their work is simply unmatched compared to any other machining company that we have used in the past. We want to ensure quality and they have repeatedly proven that their final production run meets the standards of the approved samples.
Having created multiple prototype iterations, they have developed a strong understanding of the design and are highly attentive to the tolerances between moving parts.
Our goal is to exceed the expected delivery dates, but we prefer to under-promise and over-deliver to ensure we meet, and hopefully surpass, your expectations.
You can count on us to keep you informed with regular updates on the progress of manufacturing and assembly every step of the way.
