I will see what it actually draws.
Na not using it on the Macan. I don't do any coding on the Macan. The Cayman I just did minor stuff like changing the coolant temperature to be 1:1, steering wheel profile to GT3 etc..
Can you charge the battery quickly with the Powermax?
Do NOT use the PowerMax or other to charge your battery. It's not made for that as it will not dose but provide a continuous current level. Quick charges for batteries not made for that will cause early demise of same.
