What type of in-vehicle charging systems are available for the Audi e-Tron?

I am considering purchasing an Audi e-Tron and am curious about the options for charging the vehicle while on the road. Can anyone provide more information on what types of in-vehicle charging systems are available for this car?

Audi offers two types of in-vehicle charging systems for the e-Tron: the standard Level 1 charging system and the optional Level 2 charging system. The Level 1 system uses a standard household outlet and takes about 40 hours to fully charge the vehicle. The Level 2 system uses a 240-volt outlet and can fully charge the e-Tron in about 9 hours.

For even faster charging on the go, the Audi e-Tron also has the option for 150-kilowatt high-speed DC charging. This can give you up to 80% of the vehicle's battery capacity in just 30 minutes. However, this option does require a specialized DC charger, which may not be widely available.
