Thanks. Both my Power 1000 and Power 500 needed updating and I was surprised to see in Assistant 2 there were several other updates prior that I had missed; didn't even know these units were updatable.
Reminder, a good point made in the video. You need to plug the power station into AC power or else the update will "fail" on the last step. Just like other DJI software, you can "refresh" the current version.
Thanks for pointing out the dongle; going to be my next purchase. One day, the expansion batteries will be on my list as well.
