First double-check to see that the cable is plugged in properly to the charge platform and outlet.
If you have not already, please ensure your device is making a good connection by lightly cleaning the contacts on the device and prongs on the charging base.
We recommend using a Q-tip dipped in isopropyl alcohol to clean these areas.
Wiggle PAX around a bit on the charger to see if it makes a connection, or try placing it on the platform facing the other way.
Also, try charging the device after you've removed the mouthpiece.Test another PAX charger if you have one available.
If you continue to have problems charging your PAX, please send the PAX Pros a Support Request.
