What EV Charger Do You Need for a 2025 Audi S e-tron GT?
You need a 48 amp Level 2 home charger to fill your Audi S e-tron GT overnight. The onboard charger caps power absorption at 11.0 kilowatts, making any higher capacity supply unnecessary. Your battery holds 112.9 kWh. Charging from empty takes 10.3 hours.
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 10.3 hours |
| Range added per hour (Level 2) | about 29 miles |
| Full charge on a 120 V outlet | about 78 hours |
| Range added per hour (120 V) | about 3.8 miles |
| EPA rated range | 300 miles |
| Energy for a full charge | about 112.9 kWh at the wall |
Why 48 amps and not more
Buying a unit larger than 48 amps wastes your money because the vehicle cannot draw more current anyway. If you connect a 50 amp or 80 amp supply, the car still limits intake to 48 amps. Pushing past this threshold requires electrical panel upgrades that yield zero charging speed gains. Stick to the exact rating the manufacturer built into the car. Matching the 48 amp limit gives you the fastest possible home turnaround without paying for unused capacity.
What the install involves
A 48 amp charger demands a 60 amp breaker paired with heavy gauge copper wiring. You must hardwire the unit directly to the electrical panel. Household receptacles cannot handle this continuous load safely. Call a licensed electrician to pull the wire, land it on the new breaker, and verify your main panel has spare capacity for the heavy draw. Skipping these steps risks thermal overload.

Common questions
- Can I use a standard wall outlet?
- No. Level 1 charging on a standard 120 volt household outlet yields only 3.8 miles of range per hour and takes 78 hours to fill the battery from empty. You need a dedicated Level 2 setup.
- What plug type does the car require?
- The vehicle uses a J1772 connector. Many 2025+ vehicles ship with a NACS port but include a J1772 adapter, so a J1772 home charger still works. Confirm your car port before buying.
- Why does the EPA charge time differ from the max rate?
- The EPA rated Level 2 duration is 15.5 hours at 19 miles per hour because official testing cycles account for grid conversion losses and tapering logic. Real world charging at maximum output reaches full capacity in 10.3 hours at 29 miles per hour.
- Will an extension cable work if the charger does not reach?
- You can use a J1772 extension cable rated for your current draw. Keep cable runs as short as possible to prevent voltage drop and excess heat.
Other vehicles
Charging times derived from EPA data for the 2025 Audi S e-tron GT (covering 2 EPA trim listings). Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
