["brand new and high quality\nFeature:\nA negative ion generator is a device that uses high voltage to ionize air molecules.\nNegative ions, or anions, are particles with one or more for extra electrons, conferring a net negative charge to the particle.\nAir ionizers are used to eliminate the occurrence of air-borne bacterial infections and to reduce static electricity buildup in electronics\nBy using pulses and vibration of electric appliances, rise the original low voltage to for DC high negative pressure. Making use of for DC high voltage of carbon brush tip to emitting large amounts of electronic at a high speed. Electronics can not remain in the air for a long for time, therefore,after reacting with oxygen molecules in the air, negative ions will form.\nNegative Ion Generator Accessories only, other accessories demo in the picture is not included.\n\nSpecification:\nInput Voltage: for DC 5V\nMaterial: ABS and Silicone Line\nSize: app.14x24x10mm/0.55x0.94x0.39in\nColor: As pictures shown\nQuantity: 1 Pc\n\nNote:\nNo retail package.\nPlease allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item.
