Jeasun USB-C Power Cord for Resmed AirMini – PD 20V-to-24V Boost Cable, Works with Power Banks, Car Chargers & AirMini Battery Pack, Travel & Camping Ready, 1.6m/5.2ft

I found this on Amazon and it worked for Air mini.. connection is the same though for air sense. It runs it off USB C and draws a lot of power, but you can run it off a high wattage USb c power Bank. https://a.co/d/03s5Ct5j
