about this project The electric burr coffee grinder is equipped with a ceramic grinding core for low-temperature grinding, which does not affect the original taste of coffee at all. Portable coffee bean grinders are less time-consuming and easier to operate than manual, retain more flavor than blade grinders, take up less space, and are more portable than larger grinders. The electric burr coffee grinder has multiple grind settings, simply adjust the knob to turn clockwise for a coarser grind and counterclockwise for a coarser grind. The electric coffee grinder is suitable for espresso, French press, Turkish coffee and many other flavours. Just press the coffee button on the grinder for 5 minutes for full-flavored ground coffee. The coffee grinder can only be operated safely when the grinding chamber is locked. Grinding stops automatically when there are no coffee beans in the grinding chamber. You can also press the button to stop grinding at any time while working. And the closed transparent powder bin, no powder leakage, no dirty countertop. The coffee bean grinder has a built-in lithium battery that takes just 13 hours to fully charge - 1250mAh super long life. It grinds up to 25 grams of coffee beans at a time, which takes about 5 minutes. Plus, the automatic coffee grinder can grind nuts, spices, and more. NOTE: A USB cable is included. Small and easy to carry, it fits in backpacks, handbags and suitcases. It's also great for camping, business trips, and travel. All parts except the fuselage can be disassembled for cleaning.
