The potential root cause of the damage on the mya joy plus pump power adapter type c plug may be excess "contact resistance" malfunction/failure due to contamination.Breast milk residue was found on the bottom of the pump base.The malfunction/failure did not impact or damage the returned power adapter base unit, returned mya joy plus pump's internal battery, or components on the mya joy plus circuit board inside the pump base.

Customer contacted ameda, inc.On 01/11/2023 to report an event which occurred with her ameda breast pump.She reports plugging the mya joy plus into an electrical outlet in her kitchen to charge using the ameda usb charger.She used the same electrical outlet next to a bottle warmer, not in use.She went for a walk and when she returned in 45 minutes, she smelled an odor as though plastic was burning.Customer found the end of the usb ac adapter port had melted where it connects to the pump base.Mom states that 1-2 days prior to this event, the pump screen read error when she charged the pump and the charger felt warm to touch.Customer was not harmed in this event.A replacement mya joy plus breast pump with usb ac adapter was shipped overnight to the customer.
