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

Grinding and adjustment: Chefman identifies RJ44-CB as a conical burr grinder with 40 settings spanning fine to coarse. The maker describes espresso use, but we have not tested the adjustment range for a specific basket. Chefman RJ44-CB ↗
Dosing and fit: Chefman describes direct grinding into compatible 51 mm and 58 mm portafilters. Nominal diameter alone does not guarantee that every handle and basket fit the support. Chefman RJ44-CB ↗
Capacity: The maker lists a 200 g bean hopper and 110 g grounds container. Check the seller’s current contents and allow room to refill. Chefman RJ44-CB ↗
Space and power: The reviewed manufacturer page lists a 120 W motor and 60 Hz but does not give the assembled dimensions. Confirm dimensions and voltage with the seller before planning placement. Chefman RJ44-CB ↗
