Is it possible to charge with DJI car adapter connecting HUB with 3 batteries?If so do you know if charge time is the same about wall adapter?

For the Mavic Pro? Yes you can use the hub and charge up to 4 batteries on it - the advanced hub is also compatible. It charges when the car engine is running and will charge slightly quicker than on the wall.

This is precisely my experience as well.
NB. the adaptor does need more than 12 volts (the nominal car battery voltage) so unless you have a brand new, fully charged car battery (2.2 volts x 6 cells = 13.2 volts), it will stop charging, unless the engine is running.

Thanks it’s about MP

Thanks for details

Thought so - yeah - what I wrote applies then - though it does for all Mavic's anyway.

Sorry again if I use battery car fully charged OTG so 12V doesn’t charge?

A fully charged car battery is well above 12V. If not, it may be exhausted.

It depends on the age (condition) of the battery and its state of charge.
The car charger is deliberately designed (so are most battery to mains inverters) to run at or close to 13.2 volts minimum, because once a car battery voltage drops to 11 volts, it might not start the vehicle.
That is why the car charger will shut off quite quickly unless the engine is running. Read the back of the charger. It needs a minimum of 13 volts to run.

I charge my batteries in the car using the hub and it does charge much faster as Andy mentioned
