Four major circuit protections are safe and reliable In order to the concentricity of the grinding head and the motor, we mold the square shaft and the power shaft into one piece. And the grinding area is designed in the shape of a funnel, with a space and small obstacles to quickly powder out. While upgrading the lithium battery intelligent battery management system to power, the core chip also plays the role of circuit burnout protection, which is safe and secure to use Surging power, powerful motor, fast crushing, less noise, the grinding cup and the body are detachable, no trace of powder can be hidden, easy to clean, clean with one brush, leaving no food residue, silent design, low grinding noise The capacity is easy to disassemble and easy to clean. The capacity of the storage tank is 140ml, and the rotary disassembly is more convenient. The tank can be rinsed, and the nut can be unscrewed, and the inside can be cleaned with a brush. One-handed grinding is enough to taste and quickly produce powder, restoring the taste of nutrition can retain delicate nutrition Product Name: USB Electric Grinder Battery capacity: 1000MAH Battery voltage: 3.7v Charging time: 2 hours Charging voltage: 0.5A Continuous work: 1.5-2 hours Power: 3w Material storage capacity: 140ML Function: adjustable file mute Power: 4-grid power display, rechargeable Colour:black Material:ABS Package Contents: 2 x USB Electric Grinder 2 x USB cable Only the above package content, other products are not included.
