Overview
A heptagonal conical burr of hardened stainless steel does the grinding in the OutIn Fino, driven by a rechargeable motor that starts with one button and stops when the beans are done. A dial sets fineness, and a collapsible hopper folds down for travel.
Burr grinding on battery power means fresh grounds at a campsite, a hotel room or a desk with no outlet nearby. Small capacity and a finite charge make it a personal grinder, not a household one for big batches.
Who it's for
Coffee drinkers on the move who want burr grinding in a bag, and minimalist kitchens short on counter room. Families brewing large carafes will be refilling the small hopper repeatedly.
Pros and cons
- Wide grind range on one dial
- Hardened stainless steel conical burr
- Auto start, auto stop, anti-clog reversal
- USB-C fast charging
- Small capacity per grind
- Carry-on only when flying
- Warranty not listed
- Battery limits sessions between charges
Performance notes
Grind uniformity comes from the conical burr geometry and its hardened steel, while the dial sets the gap between the burrs for each brew method. The motor reverses when beans jam, clearing them without taking the grinder apart. Battery charge governs how many sessions you get before plugging in.
