Efficient and convenient: This 200W, 120V, 60Hz electric coffee grinder features a fast grinding speed. It can adjust the grinding fineness flexibly based on the duration of pressing the cup lid, and is easily adaptable to various grinding needs. Versatile: Equipped with two independent detachable grinder cups. The single-blade cup is dedicated to grinding coffee beans, producing a uniform and fine powder. The cross-blade cup is more versatile, easily grinding various nuts, dried spices, pesto, and other wet ingredients. (Grinding coffee beans separately from spices and pesto prevents flavor mixing, resulting in a purer flavor profile.) Easy to clean: The SUS304 stainless steel grinder cup is detachable from the base and can be rinsed directly under running water or placed in a dishwasher. The included cleaning brush easily removes coffee grounds. User-friendly design: The base features an anti-slip design to stabilize the machine and ensure even grinding of ingredients. The power cord can be stored under the base, saving space and keeping the machine clean and tidy. Overheat protection: The machine has a built-in thermal temperature control switch with built-in overheat protection. It is recommended to keep each grinding session within 30 seconds; if the machine stops due to abnormal use, allow it to cool for about 30 minutes before restarting. The small scoop included with the coffee grinder holds approximately 5 grams (0.17 oz) of coffee beans per scoop.
