TIMEMORE or AMZCHEF? Coffee Grinders Compared in 2026

Key differences

Which one should you choose?

Manual Portability vs Electric Convenience

Power source

Edge: AMZCHEF 40mm Conical Burr Grinder

The TIMEMORE Chestnut C3S Pro is a manual hand grinder. You grind by turning the crank handle. This requires physical effort but offers total control over speed. The AMZCHEF is an electric grinder. It uses a motor and a smart touchscreen to grind automatically. You select time or cup count, and the machine does the work. This removes physical labor from the process. If you prefer hands-free operation or grind large batches quickly, the electric motor provides significant convenience over manual cranking.

Grind settings

Edge: AMZCHEF 40mm Conical Burr Grinder

Grind adjustment options differ between these two models. The TIMEMORE C3S Pro offers approximately 36 adjustment levels. You change coarseness by rotating the adjustment nut. The AMZCHEF provides 45 distinct settings. This wider range allows for more precise tuning across various brew methods, from fine espresso to coarse French press. The extra settings on the AMZCHEF give you finer granularity when dialing in your perfect extraction, making it a better choice if you frequently switch between different brewing styles.

Portability

Edge: TIMEMORE Chestnut Foldable Burr Grinder

Portability is a key factor for many coffee drinkers. The TIMEMORE C3S Pro features a foldable crank handle and a compact body. It weighs 15.2 ounces and measures 5.79 inches in height. These dimensions make it easy to carry in a bag for travel or camping. The AMZCHEF weighs 5 pounds and stands 14.5 inches tall. Its size and weight make it unsuitable for travel. It is designed to stay on your kitchen counter. If you need a grinder for outdoors or small spaces, the TIMEMORE is clearly superior.

Bean capacity

Edge: AMZCHEF 40mm Conical Burr Grinder

Bean hopper capacity affects how often you need to refill the grinder. The AMZCHEF includes a large removable hopper that holds up to 10.6 ounces of coffee beans. This is sufficient for multiple cups in one session. The TIMEMORE C3S Pro does not list a specific bean capacity in its specifications. Manual grinders typically have smaller hoppers, requiring more frequent refilling for larger batches. If you brew for a household or office daily, the AMZCHEF’s larger capacity reduces interruptions during your routine.

Build material

Edge: Tie

Both grinders use stainless steel for their grinding components. The TIMEMORE C3S Pro features an all-metal aluminum alloy body. This construction provides durability and helps dissipate heat during grinding. The AMZCHEF uses stainless steel conical burrs and a stainless steel container. While the burr material is similar, the TIMEMORE’s aluminum body offers a different structural profile. The aluminum is lightweight yet sturdy. The AMZCHEF’s build is heavier due to its electric motor and larger frame. Both offer solid construction for their respective designs.

Which grinder fits your routine

Travelers and campers seeking portability

Our pick: TIMEMORE Chestnut Foldable Burr Grinder

The TIMEMORE Chestnut C3S Pro is designed for on-the-go use. Its foldable crank handle reduces storage space, making it easy to pack. The compact 52 mm body fits small hands, while the lightweight 15.2 ounces construction ensures you can carry it without bulk. It is ideal for camping or travel where space is limited.

Home users wanting automatic consistency

Our pick: AMZCHEF 40mm Conical Burr Grinder

The AMZCHEF UL-CG209 offers electric convenience with a smart touchscreen. You can set precise grinding times up to 40 seconds with 0.5-second accuracy. The 45 grind settings allow you to adjust from fine espresso to coarse French press. This automation ensures consistent results without the physical effort of manual grinding.

Buyers prioritizing large bean capacity

Our pick: AMZCHEF 40mm Conical Burr Grinder

The AMZCHEF features a large removable hopper that holds up to 10.6 ounces of coffee beans. The UV-blocking tint helps keep beans fresher longer. This capacity is suitable for households that brew multiple cups daily. The built-in trap door design also helps prevent spills when removing the hopper for refilling or cleaning.
