FEATURES: The electric burr grinder consistently crushes coffee beans between ceramic conical burrs. This process retains the coffee's natural flavor and aroma better than a blade grinder. The hopper can grind up to 20 grams (enough for 3 cups) of coffee beans in a single batch. The fully automatic system allows for convenient, hands-free grinding. Put this cordless and USB rechargeable mini coffee grinder in your bag or suitcase, you can enjoy freshly ground coffee anytime, anywhere, whether at home, work, travel, hiking, or camping. The portable conical burr coffee grinder boasts multi grind settings to grind your coffee beans for any desired brewing method, from espresso to French press, - from ultra-fine to extra-coarse. With this electric coffee grinder, you will never have to worry about uneven coffee grounds, no matter which grinds size you select. Cleaning brush included for easy cleanup. The upper burr, hopper, and chamber can be removed easily for effortless cleanup. Never use water or other liquids to clean the inside of the espresso bean grinder/burrs.
