Mini Coffee Scale with Timer - Precise 0.1g Espresso & Pour-Over Scale

In this review the MHW-3BOMBER Mini Coffee Scale with Timer earns attention for home baristas and pour-over fans who need a tiny, accurate tool that fits a compact setup. The biggest reason to buy is its 0.1g high accuracy sensor that reliably detects small weight changes during extraction, making dosing and flow control simpler. It is rechargeable, pocket-sized, and offers both manual and auto timing modes, so it is especially useful for people who want precision without the bulk of a full-size scale.

Key Features

• Rechargeable 700mAh battery: Built-in lithium cell removes the need for disposable batteries and is convenient for travel when charged with a 5V adapter.
• 0.1g high accuracy sensor: Detects weight changes from 0.3g to 2000g for stable extraction and precise dosing for espresso and pour-over.
• Mini footprint: At roughly 4.1in x 4.1in and 0.6 lb, the scale fits most coffee makers and is easy to carry for outdoor brewing.
• Manual and auto timing: Normal and smart modes allow manual timing or automatic start when liquid is detected for consistent brew times.
• Pressure sensing tare convenience: The scale can turn on and zero automatically when an object over 100g is placed on it, saving steps during routine shots.
• Durable materials and design: ABS surface, silicone pads, waterproof port cover, LED display, and non-slip bottom improve everyday usability and cleaning.

Who It's For

The scale is ideal for espresso enthusiasts and pour-over hobbyists who prioritize accurate gram-level control in a small, portable package. It suits users who brew on compact machines, use small roasters or kettles, and need a travelable option for tasting or calibration.

It may be less appropriate for users who want long continuous use between charges or those who need a very large weighing platform; customer feedback is mixed on battery life, so those who demand multi-day off-grid operation without recharging should consider larger-capacity alternatives.
