Why it sits behind the Timemore Chestnut C2 Fold
The Timemore Chestnut C2 Fold (8.8) beats the 1Zpresso JX (8.7) because it is the newer design. The 1Zpresso JX leaves owners a little happier, but not by enough to close the gap.
About the 1Zpresso JX
The JX is a manual grinder built around a 48mm conical burr. The body is made from 304 stainless steel, aluminium alloy and wood, with a foldable handle. It holds 30 to 35g of coffee in the catch cup and weighs 705g. The brand rates it for up to 200kg of grinding.
Grind size is set with an internal dial, at 30 clicks per rotation. You take the grinder apart to change it, rather than turning a knob on the outside. It comes apart without tools, and a cleaning brush comes in the box. The brand describes it as made for espresso, and it also covers pour-over.
The JX is the model 1Zpresso renamed the J in 2023. The newer version has a foldable handle and a finer thread on the catch cup. 1Zpresso gives it a one-year limited warranty covering defects in materials and workmanship.
What owners report about the 1Zpresso JX
Owner feedback specific to this model is limited, and most of what we found comes from the brand's own product page and from readers writing to reviewers. Those owners are positive. They describe a solid build, an even grind and easy cleaning. Some say it beat the electric or hand grinder they had before, including a Baratza Virtuoso and a Comandante.
Speed gets the most praise. One independent reviewer found it the fastest hand grinder they had tried, at around a second per gram. The flip side is effort: the burrs are aggressive, so the crank takes real strength at fine settings. Small hands or weak grip make it harder.
The complaints are small. One owner finds 30g tight for doses of 25g or more. Another found the setting numbers confusing at first, though they got good control once used to it. Some take it travelling or camping, and one finds it bulky for that. We found no pattern of failures.
Who the 1Zpresso JX suits
Buy the JX if you make one or two cups at a time, brew pour-over or filter, and want a fast hand grinder that is easy to strip and clean. It can make espresso. One reviewer thought it better suited to manual brewing, because the steps are too coarse for fine-tuning shots, and preferred the JX-Pro or J-Max for that.
Look elsewhere if you grind a lot of espresso each morning, have limited grip strength, or want to change the setting without opening the grinder. KINGrinder K6 has external adjustment. Timemore Chestnut C2 Fold is lighter for travel. For larger doses and no cranking, Eureka Mignon Specialita is the electric espresso option.
Questions about the 1Zpresso JX
What's the difference between the 1Zpresso JX and JX Pro?
The JX Pro has a top dial for finer adjustment that you can turn without taking the grinder apart. The JX adjusts internally and is faster. One reviewer found it quicker for pour-over, and easier to take apart to clean.
Is the 1Zpresso JX the same as the 1Zpresso J?
Yes, almost. 1Zpresso renamed the JX the J in 2023, adding a foldable handle and a finer thread on the catch cup. The 48mm burr and 30 clicks per rotation are unchanged.
How do you adjust the grind on the 1Zpresso JX?
You open the grinder and turn the internal dial at the bottom. The brand gives 30 clicks per rotation. One owner found the setting numbers confusing at first, though they got good control once used to it.
Is the 1Zpresso JX good for espresso?
Yes, with limits. 1Zpresso designed it for espresso and pour-over, and one reviewer made good espresso with it. The same reviewer found the steps too coarse for easy fine-tuning, and preferred the JX-Pro for espresso.
How long is the 1Zpresso JX warranty?
One year. 1Zpresso words it as a one-year limited warranty under defects in materials and workmanship. It excludes damage from human factors, rust, and wear and tear.

The other badge winners in our coffee grinders ranking.
Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 17 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in November 2026.
