Description
Quick answer: This is the genuine ResMed 90W power supply unit (PSU) for the Air10 series — the AirSense 10 and AirCurve 10 devices (part 37474, US version). It’s the power adapter that converts wall AC into the power the device uses, and the 90W rating supports the Air10 including when heated humidification and Climate Line heated tubing are running. A direct replacement for a lost, failed, or spare power supply. Power cord and device sold separately/as noted.

About this part
Every Air10 device runs off an external power supply unit that converts wall AC into DC for the machine. This is the genuine 90W PSU for the Air10 platform — the wattage matters, because the Air10 draws more power when it’s doing more: running the built-in heated humidifier and a ClimateLineAir heated tube together increases demand, and the 90W supply is specified to handle it.
A PSU is both a replacement (they can fail, and cords/bricks get lost or damaged) and a sensible spare — many people keep a second at a vacation home or in a travel bag so there’s no unplugging and repacking. Using the genuine ResMed 90W supply ensures the correct voltage, connector, and rating; an underpowered or mismatched supply can cause the device to warn about power or limit humidification/heating.

Will it work with my setup?
This 90W PSU is for the Air10 series — the AirSense 10 and AirCurve 10. It is not for the AirSense 11 (Air11), the S9, or the AirMini, which use different power supplies. Check your device before ordering. The Air10 is specified for the 90W supply; don’t substitute a lower-wattage or non-ResMed adapter, as it can affect humidification and heated-tube performance. If you’re unsure, call us at (646) 933-0080 with your device model and we’ll confirm.

Which devices does it fit?
