This electric coffee grinder features 40 adjustable coarse and fine settings, using a precision spiral ceramic grinding core to provide consistent results for all coffee brewing methods, including espresso, roasted coffee, French press, and cold brew. Designed for efficiency and durability, the portable grinder is made primarily of ABS material and equipped with a low-noise pure copper motor that rotates evenly with strong grinding power. Simply press the power button to start, and the grinder automatically stops when the process is complete, making one-button operation effortless. The grinder is portable and USB Type-C rechargeable, featuring a 1800mAh large-capacity lithium battery that offers 125% improved battery life and allows you to grind enough coffee for 15–20 cups on a full charge. Cleaning is simple, as the parts can be easily disassembled, and the included brush helps remove residual coffee powder. The grinding chamber and transparent hopper can also be rinsed with water, though the main body should never be submerged. With a 25g hopper capacity, this grinder lets you prepare more coffee at once, reducing grinding time while giving you control over the grind size: the finer the setting, the longer the grinding time for perfectly ground coffee.
