MiiCoffee Nano Coffee Scale with Timer - Compact Espresso Precision

In this review the MiiCoffee Nano Coffee Scale with Timer is judged as a compact, purpose-built tool for espresso and pour-over enthusiasts who need fast, accurate dosing in a tiny footprint. The single biggest reason to consider it is its combination of 0.1 g precision and an optimized built-in timer, which together make routine espresso shots and small-batch pours repeatable while still fitting under most portafilters and cups.

Key Features

• New V2 layout: Charging port and switches moved to the left side reduce exposure to steam while brewing, improving longevity in an espresso environment.
• Compact size: At about 3.9 x 3.7 x 0.7 in, the scale fits in one hand and slips under many commercial group heads for direct measurement.
• Invisible LED and touch control: A clean minimalist design keeps the surface smooth for easy wiping and a neat countertop appearance.
• High precision: Measures up to 3 lbs with 0.1 g increments and supports grams, ounces and mL, giving split-second accuracy for grounds and shots.
• Dual brew timer: Built-in modes optimized for espresso (E mode) and pour-over (M mode) make timing straightforward without a separate device.
• Fast Type-C charging: An 800 mAh battery recharges quickly via Type-C and delivers around 15 hours of use per charge.

Who It's For

The Nano scale is best for home baristas and small coffee shops who need a dedicated espresso scale that fits under cups and offers precise dosing plus an integrated timer. Its minimalist surface and silicone pad appeal to users who prefer a small, tidy tool that is easy to clean.

It is less suitable for those who demand long battery endurance without frequent charging or who need a larger platform for multiple pour-over vessels. If you regularly work with heavier equipment or require extensive battery reliability, consider a larger scale with a bigger cell.
