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.
