Frequently Asked Questions
The Femobook A2 is a battery-powered portable burr grinder weighing just 650g, with a 38mm stainless steel heptagonal conical burr and over 120 grind settings. What sets it apart from most travel grinders is the replaceable battery module: rather than discarding the entire grinder when the battery wears out, the A2 uses two standard 18650 lithium cells that you can swap yourself. Add USB-C charging with power-bank pass-through, tool-free magnetic disassembly, and auto-stop with auto-reverse jam protection, and you have a genuinely capable travel grinder that does not feel like a compromise.
The Femobook A2 offers over 120 grind clicks across roughly three full rotations of the adjustment dial, with 40 clicks per rotation. Settings 3 to 10 are recommended for espresso and 50 to 80 for pour-over, with French press and moka pot also well within range. The 38mm heptagonal stainless steel burr produces a clean particle distribution with very low fines, particularly well suited to filter brewing where clarity and sweetness come through clearly.
On a full charge the Femobook A2 delivers approximately 80 grind cycles for pour-over or around 20 cycles for espresso, depending on bean density and roast level. The grinder runs on two replaceable 18650 / 10C 2000mAh cells and charges via USB-C, including from any standard power bank. It also supports pass-through use, so you can keep grinding while plugged in. Replacement cells are widely available and inexpensive, making the A2 a long-term investment rather than a disposable one.
Yes, the Femobook A2 can grind fine enough for espresso and the consistency is genuinely good for a portable grinder, but speed is the trade-off. A 20g espresso dose takes around 110 seconds, which is fine for a single morning shot but slower than most countertop grinders. For travel, camping or office espresso it works well; for back-to-back shots at home, a dedicated espresso grinder is the better fit.
Cleaning the Femobook A2 is one of its standout features. The magnetic catch cup snaps off, the burr module separates with a simple twist-lock, and the burr set, axle, spring and washer can all be removed in seconds without tools. The all-metal grinding mechanism should be brushed rather than washed unless burrs are explicitly labelled washable. A small brush is included for routine cleaning.
The Femobook A2 is designed and manufactured by Femobook, a Taiwanese specialty coffee brand founded in 2022. The company was started by engineers focused on improving burr design, axis stability and grind precision, and has built a strong reputation among home baristas and competition brewers for well-engineered, single-dose grinders. The A2 is the entry point into the Femobook range, sitting alongside the metal-bodied A4Z, A5 and A68.
