1Zpresso Q2 Review: the Travel Grinder That Fits an Aeropress
In-depth review of the 1Zpresso Q2: 38mm heptagonal burrs, 42mm Aeropress-fitting body, and travel grind quality.
1Zpresso Q2
A 38mm travel grinder slim enough to pack inside an Aeropress.
- Burr set: 38mm stainless steel heptagonal
- Adjustment: 25 microns per click, external ring
- Diameter: 42mm, fits inside Aeropress
Our verdict
The Q2 solves travel brewing completely: a 42mm body that nests inside an Aeropress, 38mm heptagonal steel burrs that genuinely deliver pour-over quality, and 25-micron clicks suited to travel brew methods. The compromises are the honest physics of small grinders: 20g capacity, slower grinding than 48mm models, and no espresso dialing. As a travel specialist it is superb; as an only grinder it asks too much. See the best manual grinders roundup for where it fits the full lineup.
What we like
- 42mm body diameter fits inside an Aeropress plunger for one-bag travel
- 38mm heptagonal steel burrs outperform ceramic travel grinders
- 25 microns per click suits pour over, Aeropress, and moka pot
- Foldable handle keeps the packed profile slim
What to watch out for
- 20g capacity means two batches for larger brews
- Not suited to espresso dialing-in
- Smaller burrs grind slower per dose than 48mm rivals
Who it is for
Travelers, campers, and office brewers who pair a grinder with an Aeropress or small pour-over dripper.
Packability
The Q2's 42mm diameter is the key number: it slides into an Aeropress plunger, turning brewer plus grinder into one packed unit. The foldable crank handle folds flat against the body, and the whole package disappears into a bag side pocket. No other steel-burr grinder here packs this small without sacrificing burr quality.
Grind quality on the road
The 38mm heptagonal stainless burrs with 25 microns per click produce genuinely good medium grinds, a clear step above ceramic travel grinders. Aeropress and pour-over recipes translate well; the grinder does not become the limiting factor in the cup. Light-roast beans take noticeably more effort at 38mm, so expect slower grinding with dense coffees.
Capacity and ergonomics
The 20g hopper covers a single serving, which matches how most people brew while traveling. Two-person brewing means two sessions. The slim body is easy to grip, though large hands may find extended grinding sessions less comfortable than with full-size grinders like the K6.
How it stacks up
Against the Porlex Mini, the Q2's steel burrs grind faster and more consistently, while the Porlex counters with a stainless body and made-in-Japan durability. Against the Timemore Chestnut C2, the Q2 trades 5g of capacity and some grinding speed for a dramatically smaller packed size. Against the KINGrinder K6, the Q2 is the travel specialist to the K6's do-everything generalist: smaller burrs, coarser clicks, far better portability.

Questions, answered
Does the Q2 really fit inside an Aeropress?
Yes. The 42mm body diameter was designed to nest inside the Aeropress plunger, a widely documented and frequently cited feature. Pair them for a complete travel brew kit.
Is 20g enough for two people?
Not in one grind. Two travelers means two grinding sessions or stepping up to the 25g Timemore C2. For solo travel brewing, 20g is exactly right.
Can the Q2 grind for espresso?
The 25-micron clicks are too coarse for dialing in espresso. It can produce fine grounds for moka pot, but true espresso needs the KINGrinder K6 or 1Zpresso JX-Pro.
Q2 vs Porlex Mini for travel?
The Q2 grinds better and faster with steel burrs; the Porlex Mini is tougher with its stainless body. Choose grind quality (Q2) or durability (Porlex) based on how you travel.
