Audi recently revamped its plug-in hybrid in 2017 with its full electric version Audi A3 Sportback e-Tron. The plug-in Audi A3 e-Tron had a battery size of 8.8 kWh (a small battery to “fill” or charge) which was fine for level 1 overnight charging. As the sizes of batteries increase and on-board charging speeds increase (how quickly you can charge the car), level 2 EV chargers such as our TOTALEV NEMA 14-50 level 2 J1772 charger and the NEMA 6-50 level 2 J1772 charger that are 240 volt charging are better portable charging options. They offer the fastest charge and will also futureproof you as battery’s increase in size in the Audi A3 e-Tron range
