The first ever Audi Q4 all electric SUV combines luxury electric driving with the practicality and performance of an Audi. Like with most newer electric vehicles, the A4 e-Tron comes with a much larger battery (more range) and battery charge acceptance (charge speed). Our most popular EV charger for the Audi Q4 e-Tron is our TOTALEV level 2 NEMA 14-50 or NEMA 6-50 40 amp charger. It is a 240 volt charger and it is the fastest portable, small footprint EV charger available for residential charging.
