What EV Charger Do You Need for a 2024 Audi Q8 Sportback e-tron ultra?
Many buyers waste money on an 80 amp charger their car cannot use. Your Audi Q8 Sportback e-tron ultra limits AC charging to 48 amps. Buying anything larger adds zero charging 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 10.7 hours |
| Range added per hour (Level 2) | about 28 miles |
| Full charge on a 120 V outlet | about 82 hours |
| Range added per hour (120 V) | about 3.7 miles |
| EPA rated range | 300 miles |
| Energy for a full charge | about 117.6 kWh at the wall |
Why 48 amps and not more
Your onboard charger maxes out at 48 amps on a Level 2 supply, drawing 11.0 kW. Going beyond this limit gains you nothing because the car physically cannot accept more power. Feeding it 48 amps restores 28 miles of range every hour. A full battery takes 10.7 hours from zero. The EPA test measures a slower 19 miles per hour because their official procedure does not run at the vehicle's maximum AC rate.
What the install involves
You need a 60 amp breaker paired with heavy copper wire to feed a 48 amp load safely. This setup demands a hardwired installation because no household receptacle handles 48 amps safely. Call a licensed electrician to pull the wire, land it on the new breaker, and check your panel for spare capacity. Do not attempt DIY work on a circuit this heavy.

Common questions
- What connector does my car use?
- Your car uses a J1772 connector for Level 2 charging. Every non Tesla electric vehicle sold in North America through 2024 uses this standard.
- Can I plug this into a standard wall outlet?
- No. Charging at Level 1 via a standard household outlet delivers only 3.7 miles of range per hour and takes 82 hours for a full charge.
- What is the EPA charge time?
- The EPA rating shows 16.0 hours for a full charge because federal test cycles do not run at the vehicle's peak AC rate. Real world charging at 48 amps takes 10.7 hours.
- Can I use Tesla Destination Chargers?
- Yes, if you buy a compatible adapter like the Lectron Tesla to J1772 unit. This allows your Audi to hook up to Tesla hardware.
