Apologies if this has already been answered elsewhere, but I've had my controller plugged into a USB-C charger for over 16 hours now and the first three green lights continue to illuminate in sequence, but never the fourth light. Is this normal?  Will it ever stop and will all four lights turn solid green?

I read in another thread that you have to activate the controller before it will complete charging. Just turn it on and complete the setup process.

thank you, will do!

Hello there ml71. I am sorry for the trouble this has caused and thank you for reaching out. Kindly please try using a recommended charger for us to be able to isolate the issue. In addition the DJI Mini 3 Pro RC Controller supports the charging power of up to 15 W ( 5 V/3 A ). Thank you.

How do I know which ones are "recommended"?  Can you send me a list of "recommended" chargers?

Another question, on the RC controller, how do I change format the MicroSD card I put in the controller?

How do I change the values the controller displays from metric to imperial?

Thank you.

I think it would pay you to search Youtube and find a video on the DJI Fly App. This would answer many of your questions.

The remote needs to be activated before it fully charges all 4 lights etc

I had the same problem that fixed itself once I activated and updated the controller.
