Gravity Electric Grinder

USB Rechargeable: Upgraded electric pepper grinder with built-in rechargeable battery. Quick charge and fully charged in one hour. No need to spend extra money on batteries like other battery-operated salt and pepper grinders. Gravity Switch: Our electric pepper and salt grinder features a gravity sensor switch. You don't even need to press a button; simply rotate the grinder and you'll have freshly ground spices—convenient and fun. Please turn on the automatic switch before use. Unique Design: The transparent acrylic material (BPA-free) at the bottom allows you to see the remaining spices and is convenient for distinguishing the spices in the grinder. With the LED light, you can easily see how much pepper, salt, and other grains you're adding to your food.
