OutIn Fino Portable Electric Coffee Grinder — 28-Position Burr, 38mm Stainless Steel Burr, USB-C Rechargeable

The OutIn Fino Portable Electric Coffee Grinder is a compact, battery-powered burr grinder with 28 precision grind positions that let you go from espresso-fine to French-press coarse while on the move.

Whether you brew at home, in a campervan, or at the office, the Fino packs professional-grade features in a small, travel-friendly package. Its 38mm heptagonal conical burr made of 420 stainless steel delivers fast, consistent particle size, while the patented 28-position dial covers the full range of grind textures. Lightweight design, one-button operation, and quick USB-C charging make it practical for daily use and for taking along on trips.

How does the 28-position dial improve grind control?

The Fino’s patented 28-position grind dial allows precise, repeatable adjustments so you can dial in extraction for different brewing methods. Instead of guessing between coarse and fine, each position changes the burr gap consistently for predictable results.

• 28 distinct positions spanning espresso to French press
• Fine graduation for consistent particle distribution
• Easy-to-read dial that stays in place during grinding

What makes the heptagonal burr reliable for daily use?

The 38mm heptagonal conical burr is manufactured from high-hardness 420 stainless steel to combine longevity with steady performance. Its shape and material reduce heat transfer and wear while producing uniform grinds quickly—important for consistent extraction and flavor clarity.

• 38mm heptagonal conical burr for uniform grind size
• 420 stainless steel rated HRC 55–60 for durability
• Engineered for efficient throughput with minimal clogging

How convenient is the grinder for travel and everyday carry?

At just 690 g with a detachable dosing cup and a collapsible bean hopper, the Fino was designed for portability without sacrificing function. It uses two 1000mAh batteries and USB-C charging to deliver up to 18 espresso shots per full charge—enough for short trips or a few days of coffee on the road.

• Lightweight 690 g build and compact footprint
• Detachable dosing cup for clean transport and easy dosing
• Fast 1-hour USB-C recharge; up to 18 espresso shots per charge

How simple and quiet is operation during a morning routine?

One-button operation simplifies the process: press to start, the grinder auto-stops when beans are finished, and anti-clog reversal handles stubborn buildup. Noise levels are kept below 60 dB(A), so it won’t disturb a roommate or early riser.

• Single-button start/stop and anti-clog reversal
• Automatic shut-off once grinding completes
• Operates under 60 dB(A) for quieter grinding

Who is this for? The OutIn Fino suits coffee lovers who want professional-style grinding in a portable form: home brewers with limited counter space, travelers and campers who need reliable gear, and anyone seeking consistent grind control across many brew methods. It’s also a good choice for commuters or small-flat dwellers who value compact design, fast charging, and precise adjustments without a large footprint.

Note: For air travel, follow airline regulations—carry the device in cabin baggage only and do not operate it during flight.
