What EV Charger Do You Need for a 2025 Audi Q8 e-tron?
You need a 48 amp Level 2 home charger to run power into the Audi Q8 e-tron at its maximum rate. The onboard charger caps power acceptance at 11.0 kilowatts, which means smaller units leave speed on the table. A 48 amp EVSE matches the car's limit exactly.
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 25 miles |
| Full charge on a 120 V outlet | about 82 hours |
| Range added per hour (120 V) | about 3.3 miles |
| EPA rated range | 272 miles |
| Energy for a full charge | about 117.4 kWh at the wall |
Why 48 amps and not more
The battery capacity sits at 117.4 kilowatt-hours, demanding heavy current to refill overnight. Pumping juice at 48 amps yields 25 miles of range per hour, completing a full tank in 10.7 hours. Buying a 50 amp or 80 amp unit wastes money because the car cannot draw past 48 amps. Feeding it less amperage only drags out your charging duration without sparing the electrical infrastructure any burden.
What the install involves
A 48 amp charger requires a dedicated 60 amp breaker and heavy-gauge wiring. You must hardwire this unit directly to the electrical supply because no standard household receptacle handles 48 continuous amps safely. Bring in a licensed electrician to pull the wire, land the leads on the breaker, and verify your main panel has spare capacity. They will mount the hardwired unit securely to the garage wall.

Common questions
- What connector does this car use?
- The vehicle features a J1772 connector. Many 2025 and newer models ship with a NACS port but include a J1772 adapter, so verify your specific port before buying hardware.
- How long does a standard wall outlet take?
- Level 1 charging on a standard household outlet delivers 3.3 miles of range per hour. A complete refill from empty takes 82 hours, making it impractical for daily driving.
- Why does the EPA charge time differ from the car's peak rate?
- The EPA test does not always run at the car's peak AC rate, listing an EPA-rated Level 2 charge time of 16.0 hours at 17 miles per hour. Real world charging at the maximum 48 amp rate finishes in 10.7 hours.
- Can I use Tesla Destination Chargers?
- Yes, if you use a Tesla to J1772 adapter. This lets your vehicle plug into Tesla hardware.
