The e-tron GT Quattro comes with a larger 93 KwH charger. At EV Chargers USA we provide a range of level 1 and level 2 chargers. For this vehicle we recommend the fastest available portable plug-in chargers which is the level 2 NEMA 14-50 or NEMA 6-50 240 volt EV charger. This provides a 40 amp, 9.6 kWH charge and will charge the vehicle in around 9.5 hours (assuming an empty battery). Most people top their charge at halfway so charging times are more than 4-5 hours. Look for out TOTALEV charger from the selector tool.
