I just got my Mavic Air 2 yesterday and I noticed while charging my batteries individually that the charging brick was making a faint buzzing noise. It never got hot but I don’t know if this is normal or something I should worry about. Maybe DJI needs to look into this. On one of the Facebook groups there are some other people reporting the same thing.

Nothing unusual about it, switch mode power supplies do that.

Hi Braves12, thanks for your feedback, if the issue happens again, any chance to record a short video so that we could forward to our engineers for further clarification? Thank you in advance.

Hi! I just received my Magic Air 2 yesterday and the adapter is making noise as well while charging. Please investigate further. Thank you! I will take a video and updated again.

I just received my flymore combo. Charger is making a buzzing noise as well as heating up.

Same problem here. Did you happen to find a solution?

I talked with dji and they said its normal

same here, got mine on 24th June...is this normal? the brick gets awfully hot while the initial charge...
the "x' marked areas is where it is the hottest.
