This cordless electric coffee machine with 8 adjustable grind settings and USB rechargeable technology isn't just another "portable coffee grinder," but rather a miniaturized coffee grinder, packed into a palm-sized aluminum container weighing only 402g. It features 38-level external stepless speed control, a real-time LCD screen display, one-handed operation, a ceramic core with zero metallic taste, and a 2-hour Micro USB fast charge. Perfect for outdoor use, showrooms, or as a VIP gift. The minimalist black and white casing can be laser-engraved with your company logo. It grinds 20g of coffee in a single batch, allowing buyers to stock up for four channels: gifts, home appliances, supermarkets, and e-commerce – making "freshly ground" a standardized product that can be ordered in bulk.
