What EV Charger Do You Need for a 2025 Audi RS e-tron GT?
A full charge takes 10.2 hours on Level 2 equipment. That speed clears a completely drained 111.7 kWh battery during a standard night of sleep. Plug in after dinner and unplug by morning. You need a 48 amp EVSE to hit this speed.
The numbers
| Maximum AC charging rate | 11.0 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 10.2 hours |
| Range added per hour (Level 2) | about 27 miles |
| Full charge on a 120 V outlet | about 78 hours |
| Range added per hour (120 V) | about 3.6 miles |
| EPA rated range | 278 miles |
| Energy for a full charge | about 111.7 kWh at the wall |
Why 48 amps and not more
Your car accepts a maximum of 48 amps of alternating current. Buying a larger charging unit will not speed up your sessions. The vehicle onboard charger limits the intake to 11.0 kW anyway. Pushing more amperage into the car is impossible. Match the 48 amp recommendation to fill the 278 mile range overnight without wasting money on oversized hardware.
What the install involves
A 48 amp EVSE requires a 60 amp breaker on the main electrical panel. No household receptacle handles this continuous load safely. Hardwiring is mandatory. Have a licensed electrician run heavy gauge copper wire directly from the breaker to the charger. Ask them to verify your panel has enough spare capacity before buying parts.

Common questions
- Can I use a standard wall outlet?
- Level 1 charging on a standard household outlet takes 78 hours for a full tank. It adds only 3.6 miles of range per hour. You must install a Level 2 setup for practical daily driving.
- Why does the EPA estimate take 15.5 hours?
- The EPA testing protocol accounts for grid inefficiencies and thermal management losses during a full cycle. The car's maximum hardware rate still delivers a full charge in 10.2 hours under normal conditions.
- What connector does this car use?
- The vehicle features a J1772 connector port. Many units ship with a NACS port during the industry transition, so inspect your specific hardware. An adapter handles Tesla destination chargers if needed.
- Do I need a 50 amp charger?
- Your car maxes out at 48 amps. A 50 amp unit will step down its output to match the vehicle limit. Stick to a 48 amp circuit.
