【Swappable Battery Design for Longer Lifespan】
Yuan Cafe Owner notes that the Femobook A2 rechargeable grinder weighs just 650 g, about the same as a 600 ml bottle of mineral water. Its lightweight design makes it extremely portable.
The A2 uses a Type-C charging port and features a replaceable 18650C battery. If the battery degrades over time, users can easily replace it themselves.
There is no need to worry about battery aging affecting the machine’s lifespan. He sees this design as both practical and a key factor in extending the overall life of the grinder.
In terms of battery life, official data states that the A2 can grind 20 to 60 sessions on a full charge. Yuan Cafe Owner explains that actual results will vary depending on bean type and roast level.
For example, dark-roasted beans are more brittle and can allow up to 60 grinds. However, lightly roasted beans, which have more moisture and density, require more power and may result in around 20 grinds per charge[1].
Yuan Cafe Owner also points out that the grinder features smart detection. It runs up to 200 seconds per session, but if it senses there are no beans, it automatically stops within 8 seconds.
If left idle for a full minute, it shuts off automatically. He finds these features very user-friendly and helpful for a smooth experience.

【Dual Support with Espresso-Fine Grinding Performance】
The Femobook A2 is suitable for both espresso and pour-over. Yuan Cafe Owner explains that the grind adjustment ring offers 40 clicks per rotation.
According to official guidelines, settings 3 to 10 are ideal for espresso, while 50 to 80 work best for pour-over[1].
In his espresso test, Yuan Cafe Owner used the finest recommended setting and produced grounds as fine as flour, suitable for home espresso machines. The grinder ran smoothly without stalling or feeling overworked.
However, since the grinds cup is made of plastic, static can cause coffee grounds to cling inside the cup. He recommends lightly spraying water onto the coffee beans before grinding to reduce static.
For pour-over grinding, the A2 provides a wide range of adjustments. While some visible boulders may appear in the ground coffee, there is still enough fine powder to help stabilize the flow rate during brewing and achieve the desired total extraction time.
The A2 also includes auto-stop functionality, so there’s no need to manually turn it off after grinding. Yuan Cafe Owner finds this feature very convenient.
He also reminds users that unless a burr set is explicitly labeled as washable, grinders should not be cleaned with water[2].
Additionally, Yuan Cafe Owner emphasizes that the A2 grinder is beginner-friendly. Even without hitting the perfect grind “sweet spot,” it still brews coffee with good body and sweetness. This consistency makes brewing feel much more approachable and smooth.

2. The A2 features a motor-and-burr separation structure. It opens with a simple twist, allowing thorough cleaning with a brush or air blower, reducing the need for water and minimizing the risk of rust or metal damage.
【Low-Speed Grinding Preserves Flavor and Improves Consistency】
Yuan Cafe Owner points out that the A2 grinder uses a low RPM motor, running even slower than most manual grinders.
Although the grind time is slightly longer, this slower speed improves grind consistency and better preserves the original flavor of the beans.
With slight brewing process adjustments, he believes this doesn’t affect the workflow and instead enhances cup quality.
In his brewing test, the A2 produced a cup with full body, smooth texture, and rich depth. Unlike the light floral-fruity profiles commonly found on the market, this grinder brings out bold notes of caramel, butter, and nuts.
As the coffee cooled down, he could feel delicate fruit aromas such as peach and pear, which added a layered complexity to the experience.
Yuan Cafe Owner also mentions that the burrs are designed to retain an optimal amount of fines. This helps stabilize extraction and enhances the cup’s flavor layers. Even for beginners, it’s easy to brew a well-balanced and flavorful cup.
【Yuan Cafe Owner’s Review: Beginner-Friendly and Worth Considering】
Yuan Cafe Owner mentions the Femobook A2 weighs just 650 g, matching the weight of a standard bottle of water.
Its compact, lightweight design makes it ideal for camping, travel, or office use. It meets the demands of modern coffee lovers who value portability and simplicity.
In terms of usability, he praises the intuitive operation. The grinder uses a touch-sensitive button that requires a long press to start, which helps prevent accidental activation.
The auto-stop feature ends grinding when complete, and if left running too long, the internal safety system shuts the motor off. These smart features make the grinder feel especially user-friendly.
The magnetic top lid and grind cup also make assembly and cleaning easier. With a quick twist, they come off for maintenance using a brush or air blower. This saves time and effort during cleaning.
In terms of performance, the A2 handles both espresso and pour-over with ease. Yuan Cafe Owne does note that extremely light roasts for espresso may challenge the burrs and could cause occasional stalling. However, for other roast levels and pour-over settings, it performs reliably.
In summary, Yuan Cafe Owner believes that for just under 100 USD, Femobook A2 grinder delivers impressive grind quality. With its simple interface and beginner-friendly design, the A2 is a high-value entry-level grinder that is absolutely worth considering.
