FEMOBOOK A2 Portable USB Electric Coffee Grinder is a rechargeable burr grinder built for fresh, consistent coffee at home, work, travel, or camping. With 38mm 7-core stainless steel burrs, a 4000mAh battery pack, 35g bean capacity, and USB-C charging, it gives you precise grinding without the size of a countertop grinder.

Key Features

• 38mm 7-core heptagonal stainless steel burrs help deliver more uniform grounds for espresso, pour over, moka pot, French press, and cold brew.
• 4000mAh rechargeable battery using 2 included 2000mAh 18650 cells supports up to 80+ pour-over grinds per charge.
• Magnetic attraction design allows quick tool-free disassembly for cleaning and maintenance.
• Compact 60 × 60 × 210 mm body and about 0.65 kg weight make it easy to pack for travel coffee setups.
• Adjustable grind settings give fine-step control across multiple coffee brewing methods.
• Full-metal grinding chamber paired with a durable plastic body helps reduce noise while keeping the grinder portable.

Compared to blade grinders, the conical burr system is designed to produce a more consistent particle size with fewer fines, which helps improve flavor clarity and extraction. Unlike many larger electric grinders, this one fits easily in a backpack and charges from a power bank, laptop, or wall adapter.

It pairs well with a pour over dripper, moka pot, French press, or travel coffee mug setup when you want fresh ground coffee on the go. Included in the box: FEMOBOOK A2 grinder, battery pack, USB-C charging cable, and cleaning brush.
