The Femobook A4z is a portable, battery-powered electric coffee grinder designed primarily for filter and pour-over brewing. It is manufactured by Femobook, a Taiwanese company established in 2022 that focuses on creating innovative and user-friendly designs for coffee enthusiasts. A former 1Zpresso engineer founded Femobook with the goal of delivering exceptional grind quality and precision without unnecessary cost or complexity.
The A4Z utilizes 48mm stainless steel conical burrs, with the same geometry as the 1Zpresso ZP6 manual grinder, known for producing a clean, sweet cup profile with excellent consistency. It features a low-RPM motor to preserve delicate flavors and a click-precise dial for repeatable grind settings. The grinder has a capacity of approximately 30-35g of coffee beans and is powered by a rechargeable 6000mAh battery, providing roughly 30-50 uses per charge via USB-C. It also features tool-free disassembly and comes with a carry case for portability. The price of the Femobook A4z ranges from $499 USD to $659 SGD, or €495, depending on the retailer. Availability may vary, with some retailers indicating they are re-stocking soon.
