Charging Case and linking by itself are one of the reason I purchased DJI MIC.
There is third party charging case for Rode Wireless GO II.
Rode Wireless GO II is $50 cheaper than DJI MIC(dependent website) average.
However the charging case is about $50 so I think it is about same price range.
If the price range is same, DJI MIC charging case is DJI, not third party.
When green light is on, it is ready to use it.
It record on transmitter also that can save your shoot.
Sometime there is issue with record sound delete or corrupt then you can use that as back up.
It comes with Transmitter x2, Receiver x1, Charging Case x1, Pouch x1, Cable for connect to camera, adapter for iPhone and Android phone.
This will make mic always has battery when you take out from case.
I will use this mic and lavalier mic so easy to get dialogue.
If you are still debating which mic you are going to get.
DJI will be best choice for that price.
