Thank you for reminding me i replied in this thread. I have an update. i had been browsing a few days ago On the main thread for charging issues
I could not find the message, but I saw EPR and PD 3.1 mentioned as “preffered” by the chipset somewhere. My 737 is neither of those, although it does put out enough power.
I confirmed that the issues went away when testing a few chargers that are rated as EPR, and now i have ordered one which makes 3 chargers tested and confirmed problem free.
If you have a usb c macbook charger, some of those might work.
