Does anyone know if the OSMO 57W power adapter will work with the OSMO battery extender?  I need a way to power the my OSMO+ via AC.

So just to be clear...  If I purchase the PH4C100 charger, I can plug the round barrel connector into the OSMO extender and power my OSMO+ off the AC outlet?

Hi there, sorry for the late response, you will need to plug in the PH4C100 charger to your AC outlet for you to charge the battery extender or to power up the OSMO+. For additional information, if you want to use Osmo External Battery Extender without an AC outlet you'll need to use an external power sources such as a dedicated DJI Intelligent Battery. Please see attached image below for example. If you have other concern please let us know. Thank you.
