Overview¶

The Femobook A2 and A5 (also branded as FIMO) are compact electric coffee grinders positioned at different points in the portable/semi-portable category. The A2 is a lightweight, filter-oriented grinder with a 38 mm burr set; the A5 is a more capable step-up with a 53 mm stainless steel conical burr, micro-adjustment, and features designed to support both filter and espresso use.

Burr Specification¶

Feature	A2	A5
Burr diameter	38 mm	53 mm conical
Material	Steel	Stainless steel
Primary use case	Filter	Filter and espresso
Grind distribution	Reported coarse-forward with few fines at filter settings	Broader range; espresso-capable

The 53 mm burr in the A5 provides greater cutting area, faster throughput, and more consistent particle distribution at espresso grind settings. The A2's smaller burr is optimised for filter clarity.

Adjustment System¶

The A5 features approximately three full rotations of adjustment range with 100 clicks per rotation at 0.008 mm (8 microns) per click. This micro-step adjustment is particularly significant for espresso dialling-in, where small grind size changes are required to hit narrow extraction windows.

The A2 provides adequate adjustment range for filter brewing but is not documented to the same micro-step precision as the A5.

Power and Capacity¶

Feature	A2	A5
Battery capacity	2× 2,000 mAh (18650)	6,000 mAh
Estimated capacity per charge	~35 ±5 g	30–50 uses per charge
Weight	~0.65 kg	Heavier
Automation	Standard	90-second timer cycle; auto-stop on charge

The A5's larger battery platform and automation features suit higher-volume or espresso-first use.

Retention and Cleaning¶

The A5 includes a magnetic brush integrated near the burr set to reduce grounds retention during grinding, and tool-less disassembly for cleaning. These features support more frequent cleaning cycles, which is relevant for espresso preparation where flavour cross-contamination from retained grounds is more impactful than in filter brewing.

Flavour Outcomes by Method¶

Filter brewing: Both grinders produce clean filter results. The A2's reported low-fines distribution at pour-over settings produces high-clarity cups suitable for showcasing origin character.

Espresso: The A5's larger burr, micro-adjustment precision, and lower-retention design make it the more capable option for consistent espresso results. The A2's filter orientation does not preclude espresso use, but the adjustment range and retention characteristics are less suited to it.

Use-Case Summary¶

Use case	A2	A5
Filter-only household	Well-suited	Over-specified
Travel / compact setup	Well-suited (lighter)	Less suited
Filter and espresso	Limited espresso capability	Well-suited
High-frequency use	Limited battery capacity	Better battery endurance

Key Facts¶

A2: 38 mm burr; ~0.65 kg; filter-primary; ~35 g capacity
A5: 53 mm stainless steel conical burr; 8 microns per click adjustment; 6,000 mAh; 30–50 uses per charge
A5's micro-adjustment system (8 microns/click) is suitable for espresso dialling-in; A2 is less documented for espresso precision
Both marketed under "Femobook" branding (FIMO is an alternative rendering used in some markets)
