Removable Battery for Oxygen Machine

Purchasing our additional backup batteries, which have a capacity of 3300mAh, can significantly extend the life of the oxygen machine. Each battery provides a continuous oxygen supply for approximately four hours and has a service life of two to three years. It also has fast charging and charging-while-in-use functions, which can meet the continuous oxygen supply needs of long-term outdoor activities such as long-distance driving and high-altitude hiking. The extended battery configuration further increases the device’s usage time, providing stable and uninterrupted oxygen support outdoors or when traveling away from a power source.
