The user alleged he saw sparking and flames, which he extinguished by blowing them out. There was no harm or injury reported. The durable medical equipment provider also reported to the manufacturer that the user had a non-approved power supply in use with the device when they assessed it at the home. The manufacturer received the cpap device, associated humidifier, and the power supply/cord for investigation that is approved for use with the device. The non-approved power supply/cord was not returned. There was evidence of thermal damage and deformation to the power supply dc output connector and dc power supply. There was also evidence of water ingress at the dc port and internally. There was no evidence of thermal damage internally.
