For a while, when I could get it to work, I would swear that the car charger charged the M2 battery faster than the AC charger.
Looking at the specs on the chargers, turns out I am correct.
The AC charger is rated 60W and only puts out roughly 3.5A.
The car charger though puts out 4.5A.
Input voltage/current on the car charger makes it a 91W charger.
I also swore the RC charged faster with the M2 battery using the powerbank adapter.
If you are charging your RC at the same time as the M2 battery, it may take even longer, unless the charger runs at a higher wattage under that load than it's rated for.
