Electric Coffee Grinder with 1800mAh Battery

This rechargeable electric coffee grinder features a 1800mAh battery that delivers up to 30 cups per charge, eliminating the need for outlets or manual cranking. The ceramic conical burr grinds beans at low temperatures to preserve flavor, while the pure copper motor operates quietly with 30% more efficiency than standard motors. An external adjustment dial offers 40 grind settings from ultra-fine espresso to coarse French press, and the RIS (Resistance Induction System) automatically stops grinding when complete. The entire unit charges via USB-C, weighs just enough to stay stable during grinding, and fits easily in a backpack. The transparent collection chamber holds 25 grams of ground coffee and detaches for easy pouring.

Use any standard USB charging adapter or power bank. Coffee beans not included. Usage Tips Charge the grinder fully before first use using the included USB-C cable. For best results, fill the bean chamber no more than 25 grams to ensure even grinding. Press the power button once to start grinding—the grinder will automatically stop when beans are fully ground thanks to the RIS sensor. Adjust the external dial clockwise for finer grinds (lower numbers for espresso) or counterclockwise for coarser grinds (higher numbers for French press). The ceramic burr can be rinsed with water after use, but make sure it’s completely dry before reassembling. Charge after every 20-25 uses to maintain optimal battery performance, and avoid grinding oily or flavored beans that can clog the mechanism. Why Choose This Product? Manual grinders require effort and time, while plug-in electric grinders tether you to an outlet. This battery-powered grinder solves both problems by delivering motorized convenience anywhere you need fresh coffee. The 1800mAh battery capacity means you can grind for weeks without recharging, and USB-C charging works with the same cable you use for your phone. The ceramic burr is the key advantage over metal burr grinders. Metal burrs heat up during grinding, which can cook your coffee and destroy delicate flavor compounds. Ceramic stays cool, preserving the oils and aromatics that make fresh-ground coffee worthwhile. The 40-speed adjustment gives you more precision than most portable grinders, which typically offer only 3-5 settings. The RIS auto-stop feature prevents over-grinding and saves battery life by shutting off the motor as soon as resistance drops, indicating all beans are ground. This grinder works equally well for someone who needs quick espresso grinds before work, a traveler who wants fresh coffee at hotels, or an outdoor enthusiast brewing pour-over at the campsite. It’s fast enough to replace a countertop grinder yet portable enough to pack for a weekend trip.
