The OxyGo AC power supply is specifically designed to power the OxyGo Portable Oxygen Concentrator (1400-1000). The AC power supply provides the precise current and voltage required to safely power the OxyGo and is designed to operate from specified AC power sources. When used with AC power sources, the power supply automatically adapts to input voltages from 100V to 240V (50-60HZ) permitting use with most power sources throughout the world. The AC power supply will charge the OxyGo Batteries when used with AC input power. Due to aircraft power limitations, the AC Power Supply cannot be used to charge the OxyGo Battery when used on an aircraft.
