TIMEMORE vs Tuni Grinder Specs
Power source
The TIMEMORE Chestnut C3S Pro is a manual coffee grinder. You grind beans by turning the crank handle yourself. This model relies entirely on human effort and includes a built-in bearing to smooth the motion. In contrast, the Tuni G1 is an electric coffee grinder. It uses a motor to grind beans automatically. This allows for hands-free operation and consistent speed without physical exertion. You choose between manual control and electric convenience based on your preference for effort versus automation.
Grind settings
Adjustment options differ between these two machines. The TIMEMORE Chestnut C3S Pro offers approximately 36 grind settings. You adjust coarseness by rotating the adjustment nut, moving from fine to coarse. The Tuni G1 provides 48 precision grinding settings. This electric model also allows you to customize grind time in 0.5-second increments up to 40 seconds. Both offer multiple steps for tuning, but the Tuni G1 has a higher number of discrete settings and time-based control for finer adjustments.
Portability
Design intent varies significantly for travel. The TIMEMORE Chestnut C3S Pro features a foldable crank handle and a compact body measuring 52 mm in width. It weighs 15.2 ounces, making it easy to carry in a bag for camping or travel. The Tuni G1 is a stationary electric unit. It weighs 4.8 pounds and measures 14.0 inches in height. Its size and weight make it unsuitable for portability. It is designed for fixed placement in a kitchen or cafe setting rather than on-the-go use.
Burr construction
Both grinders utilize conical burrs made of stainless steel. The TIMEMORE Chestnut C3S Pro uses the S2C660 patent hexagonal conical burr with 55-58HRC hardness. It is machined via 5-axis CNC to minimize coarse grains and fine powder. The Tuni G1 features a patented anti-static 40mm conical burr. It operates at a low speed of 450 RPM to reduce heat buildup and static. While both use stainless steel, the TIMEMORE emphasizes hardness and machining precision, whereas the Tuni focuses on low-speed anti-static performance.
Bean capacity
Storage capacity impacts how often you refill beans. The Tuni G1 includes a large 250g (8.8oz) bean hopper. This allows you to grind multiple cups without adding more beans. The TIMEMORE Chestnut C3S Pro is a manual grinder with no specified bean hopper capacity in the data. Manual grinders typically hold a smaller amount of beans in the top chamber, requiring more frequent refilling for larger batches. The Tuni G1 offers significantly higher capacity for continuous grinding sessions.
