Figures for the 2018 A3 e-tron. The battery is small enough that even a 120 V outlet fills it in about 5 hours, overnight.
| Charger | Power | 20% to 80% | 0% to 100% |
|---|---|---|---|
| Level 1, 120 V outlet (12 A) | 1.4 kW | 2 hr 45 min | 4 hr 35 min |
| Level 2, 240 V, 16 A | 3.8 kW | 1 hr 2 min* | 1 hr 43 min* |
| Level 2, 240 V, 24 A | 5.8 kW | 41 min* | 1 hr 9 min* |
| Level 2, 240 V, 32 A | 7.7 kW | 31 min* | 52 min* |
| Level 2, 240 V, 40 A | 9.6 kW | 25 min* | 41 min* |
| Level 2, 240 V, 48 A | 11.5 kW | 21 min* | 34 min* |
* Only if the car's onboard charger accepts that much power. On its EPA test it charged at about 2.6 kW; if that is its limit, a faster wall charger won't shorten the 2.5-hour full charge.
