Espresso Scale with Auto Timer and 0.1g Accuracy - Compact White

In this review the MHW-3BOMEBR espresso scale is evaluated for home baristas and pour-over enthusiasts who need precise doses and consistent extraction. The bottom line: this compact white scale delivers 0.1g accuracy and an intelligent timer that starts with liquid detection, making it a strong choice for anyone who measures by weight and time. It is especially useful for those working with small doses or limited counter space, though users should be aware of mixed reports about long-term battery behavior.

Key Features

• High accuracy: The 0.1g resolution sensor registers weights from 0.3g to 2000g so small changes in dose are reflected immediately for finer extraction control.
• Auto and manual timing: Two timing modes let users run a manual stopwatch or use intelligent mode to auto-start the timer when the scale detects liquid contact.
• Auto and manual tare: The scale can wake and auto-tare when an object over 100g is placed on it, and the power button also functions as a manual tare during use.
• Compact footprint: At roughly 4.9 by 4.9 by 0.9 in and weighing 0.72 lb, it fits under espresso machines and inside pour-over holders without taking much counter space.
• Rechargeable battery: A built-in 1500mAh cell charges with Type-C for extended use between charges when following the recommended low-power adapter guidance.
• Dual units: Switchable g/oz units simplify work with different recipes and international measurement preferences.

Who It's For

The scale is aimed at home baristas, pour-over fans, and anyone who needs fine-grain control over coffee dosing and extraction time. Its small size makes it ideal for tight counters and for users who pair a scale directly with an espresso machine or pour-over stand.

It may be less suitable for heavy commercial use or anyone who needs an ultra-robust device for constant, high-volume shifts; some customers reported inconsistent battery behavior over long-term use, so those who cannot tolerate any downtime should consider a dedicated commercial scale.

Pros & Cons

Pros

• Excellent accuracy down to 0.1g, which helps achieve repeatable shots and pours.
• Intelligent timing with solid-liquid detection reduces manual steps during extraction.
• Very compact and lightweight, making it easy to position under machines and in tight setups.
• Rechargeable Type-C battery with relatively high capacity reduces frequent charging needs.

Cons

• Some users report mixed experiences with battery life and charging performance over time.
• The automatic tare wake is threshold-based and may not trigger for lighter accessories under 100g.
