【Asser - A Nordic Coffee Expert with Global Recognition】
Asser, hailing from Northern Europe, is a dedicated coffee content creator. Holding a Q Grader certification, he shares in-depth coffee knowledge through his YouTube channel and personal blog.
Currently based in Chiang Mai, Thailand, Asser continues to explore various coffee equipment and brewing techniques, offering insightful and practical perspectives for coffee enthusiasts worldwide.
【Cord-Free Convenience with Long Battery Life】
Asser previously had a great experience using the Femobook A68, leaving him with a strong impression of the brand and high expectations for the A5 electric grinder.
He highlights A5’s biggest advantage over traditional plug-in models like the A68—its battery-powered design.
According to Asser, battery life is a crucial factor when choosing a rechargeable electric grinder. The A5 surpasses a competing brand featured in the video, delivering 30 to 50 grinding sessions per full charge.
Additionally, it is equipped with a rear USB-C charging port, enabling quick and hassle-free charging for daily use[1].

【Minimal Retention & Tool-Free Quick Disassembly】
Asser highlights the A5’s signature magnetic assembly, where all components are securely attached with magnets, enabling effortless tool-free disassembly.
In addition, the A5 is sleeker, more compact, and more portable than the A68. Its space-saving design makes it ideal for home use and travel.
He also addresses a common issue with many grinders—static retention in espresso grinding. To solve this issue, the A5 is equipped with a detachable magnetic cleaning brush beneath the burrs, which sweeps residual coffee grounds as the burrs rotate, reducing static cling.
After testing with 15g of coffee beans, Asser found that the grinder retained only 0.1g of grounds, significantly minimizing retention issues.
【Faster and More Versatile Than Competitors—No Bean Jams】
Asser highlights the A5’s wide-ranging grind size adjustment mechanism, making it equally suitable for pour-over and espresso.
However, due to the precision grind settings, users should take extra care when switching between brewing methods, as the adjustment ring lacks rotation markings for reference[1].
Through a direct test with the other electric grinder, Asser found that when grinding 15g of espresso coffee, despite the A5 being slightly louder, it is faster than the competitor about 30 seconds.
Additionally, it operated smoothly without jamming. The built-in sensor also automatically detects when grinding is complete and stops the motor accordingly[2].

2. The A5 produced approximately 75 dB of noise during operation. Since noise perception is subjective, users can experience it by themself.
【Asser’s Review: Delicate and Interesting for Pour-Over, Balanced and Smooth for Espresso】
After extensive testing, Asser commends the A5’s conical burrs for their exceptional performance in pour-over. Compared to the competing grinder, the A5 offers superior extraction quality, producing a more refined and delightful flavor profile.
For espresso, he finds the A5 brings out the distinct characteristics of conical burr grinding, producing a smooth and balanced shot without excessive heaviness.
Additionally, Asser commends the A5’s build quality and sleek design. While he notes that its weight might not be ideal for his ultra-light travel preference, its outstanding battery life eliminates the need for frequent recharging, making it a highly satisfying grinder to use.
