Enjoy a life of freedom of mobility with the ARYA Airtivo Max DC power supply, your trusted on the go charging companion for your ARYA Airtivo Max portable oxygen concentrator. This power supply's primary role is to ensure your ARYA Airtivo Max battery stays charged, even when you're on the move. Simply connect the DC power supply to a 12v outlet – found in your car, truck, RV, or boat – and you're good to go. This ability to charge your ARYA Airtivo Max on the go gifts you the liberty to be more mobile and travel without any hassles. Most vehicles come equipped with a 12v outlet or a cigarette lighter that you can use to power up your ARYA Airtivo Max portable oxygen concentrator. Despite the DC power supply drawing from your vehicle's battery, you can still operate your ARYA Airtivo Max while it's plugged into your vehicle and charging. While this may extend the charging time for your batteries, the ability to top off your battery on the go gives you the confidence you need to travel and live a more mobile lifestyle.
