Plasma cluster ion generator, compact design with USB connection. I had it installed in my car, which I only use on weekends. I am a non-smoker. There are many scratches and stains from use. The only included accessory is the USB cable. I confirmed that air comes out before listing. Please understand that the usage time of the ion generation unit is unknown before purchasing. - Brand: SHARP - Model: IG-NX15-B - Year of manufacture: 2020 - Function: Plasma cluster ion generator - Power supply: USB connection
