Option-O · Conical burrLagom Mini 2
A pocket-sized, single-dose conical grinder that swaps Option-O's old proprietary power brick for USB-C PD, aimed at travelers and anyone who wants a tiny, precise second grinder rather than a countertop hog.
The short version
This is the grinder you buy when you want P64-grade machining and a genuinely portable form factor, not raw throughput.
Accept the slow grind time and the fussy USB-C PD3.0 charger requirement, and it rewards you with clarity most compact grinders can't touch.
Why people buy it
- Genuinely the smallest precision electric grinder we've seen, at 65 x 95 x 240mm and 1.5kg, and it still packs 48mm conical burrs
- USB-C PD3.0 power means one less proprietary brick to carry, and it can even run off a good power bank
Why they don’t
- Slow: an 18g espresso dose can take 45-60 seconds, and there's a strict duty cycle (roughly 90s rest between shots, max 4 shots per 10 minutes)
The full tally
- Genuinely the smallest precision electric grinder we've seen, at 65 x 95 x 240mm and 1.5kg, and it still packs 48mm conical burrs
- USB-C PD3.0 power means one less proprietary brick to carry, and it can even run off a good power bank
- CNC-machined, anodised all-metal build with dual P5-grade bearings feels like it will outlast cheaper grinders many times its price
- Low-retention single-dose design with a magnetised catch cup keeps fresh coffee fresh and workflow clean
- Slow: an 18g espresso dose can take 45-60 seconds, and there's a strict duty cycle (roughly 90s rest between shots, max 4 shots per 10 minutes)
- Stepless dial has no numbers, just dots, so dialing in and repeating settings takes a personal system and some patience
- Requires a specific, fairly high-power PD3.0 USB-C charger (20V/5A/100W); many common chargers, including some Anker models, won't work
What the community knows
Years of owner threads, distilled — a niche favourite.
Premium conical burrs and hand-built quality earn respect, but motorized-hand-grinder speed, strict 1:1 duty cycle, and USB-PD3.0 dependency chain it to minimalists with existing USB-C infrastructure or second-grinder buyers—never a beginner default.

Worth knowing before you buy — Most owners wish they'd accepted the speed limit before buying—not a "faster hand grinder," just a button-press hand grinder.
Known weak points — Original Mini: historical burr coating defect (resolved in Mini 2 via Mizen 48MS). USB-PD3.0 adapter incompatibility (documented on Home-Barista Jan 2025)—common source of user friction if non-compliant adapters supplied.

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who outgrow the duty cycle or want a bigger hopper for daily multi-shot use typically step up to Option-O's own Lagom Casa or a P64-class single-dose flat/conical grinder; this stays a great secondary travel grinder even after that move.

Before it arrives
What completes this grinder — the faded pieces can wait.
Coffee scale with timer — Espresso is a ratio. A 0.1g scale with a built-in timer is the single biggest consistency upgrade for any manual machine.

- Dosing cup — Pairs with single-dose grinding — grind into the cup, swirl, and transfer to the portafilter cleanly.
- Grinder cleaning kit — Brushes and grinder tablets keep retention and stale grounds in check.
Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. These burrs lean bright — washed single-origins with real acidity are where they earn their price.

Common questions
Can the Lagom Mini 2 grind for espresso?
Yes, Option-O states it can be used for both espresso and filter coffee, though it is intended for non-commercial use with a recommended duty cycle.
Are the Mini 2 burrs compatible with the original Lagom Mini?
No. The Mizen 48MS burrs in the Mini 2 use a different burr mount system and are not cross-compatible with the first-generation Lagom Mini.
What charger does the Lagom Mini 2 need?
It requires a USB-C PD3.0-compliant power source capable of 20V/5A (100W); lower-power or non-PD3.0 chargers will not work reliably.
Worth comparing
DF64
DF64P
A bottom-adjust, espresso-only variant of the DF64 single-doser, with 64mm flat burrs relocated to the base for a lower center of gravity and tighter espresso-range adjustment.
