For my personal situation, the only thing i would really need are the two batteries. I already have an unused camera bag lying around which would be perfect for the Mavic and all components. As far as charging goes, i don’t mind using the standard charger as I mostly charge my batteries the day before. Once I have multiple batteries, I will look for a device that charges them simultaneously.
On my previous drone, I haven’t lost / broken any of the provided props and they even included less propellers than DJI does. I think the provided ones will cover me well enough and if I do need some, I’ll just get some from my local store.
The battery-to-powerbank adapter is obsolete, as I have recently purchased an overkill powerbank with drone flying in mind. Also, the remote will now charge my phone, so the only thing that will need to be charged on the go is the remote. My powerbank will cover that.
Now all that is left is the car adapter...
Maybe (if I ever need it) I’ll get it separately.
