AAOBOSI Cordless Burr Coffee Grinder with 60 Settings

A closer look for your small-space coffee setup.

Amazon lists this rechargeable grinder at 9.1 in long x 4.2 in wide x 12 in high, with 60 settings and a USB-C charging cable. Confirm clearance to refill the hopper and check the fit of your exact portafilter; advertised battery life and espresso performance have not been independently tested.

DOCUMENTED DETAILS

What we found in the sources

Document review: November 12, 2026. Seller offers may differ. This is research, not a hands-on test.

Grinding: The AAOBOSI HB-686-BK product page describes 60 settings and a 40 mm stainless-steel conical burr. We have not tested the setting range or espresso performance of the selected Amazon variant. AAOBOSI HB-686-BK product page ↗
Battery: conflicting capacity: The manufacturer page specifies a 2,600 mAh battery for HB-686-BK, while a listing for this ASIN advertises 8,000 mAh. Ask the seller which battery and runtime apply to the exact unit; neither claim is independently tested. AAOBOSI HB-686-BK product page ↗
Listing battery claim: A separately indexed listing for this ASIN advertises 8,000 mAh. This conflicts with the manufacturer page; confirm the variant and do not rely on either runtime estimate without checking. Indexed Amazon listing for B0FQNSM2KH ↗
Charging and dose: The manufacturer describes USB-C charging and a timer. A timed dose is not a weight measurement: use a scale if repeatable coffee doses are important. AAOBOSI HB-686-BK product page ↗
Space: Amazon lists 9.1 × 4.2 × 12 in (length × width × height). Verify the orientation and reserve additional room to refill the hopper, connect the cable and use the support. Amazon product listing ↗
Parts and fit: The manufacturer page lists a grounds cup, cleaning brush and portafilter holders. The contents may vary; check the exact Amazon bundle and portafilter fit before purchasing. AAOBOSI HB-686-BK product page ↗

Still unknown: We have not reconciled battery capacity or measured runtime, grind quality, portafilter fit or noise. The manufacturer page may describe a different market variant.
