Built-in 2000mAh lithium battery provides multiple uses on a single charge, offering longer life and safe performance compared to standard batteries. Effective sterilization and disinfection: Utilizes the ozone "sterilization" effect to thoroughly disinfect hard-to-clean areas of ventilators, tubing, masks, and humidifiers. Low noise operation ensures a quiet and comfortable experience, enabling users to complete oxygen concentrator disinfection in a peaceful environment.
