What EV Charger Do You Need for a 2024 Audi Q4 Sportback 55 e-tron?
Many buyers make the mistake of purchasing an 80-amp charger that their car cannot use, wasting both money and installation overhead. Your Audi Q4 Sportback 55 e-tron tops out at 48 amps for Level 2 charging. You need a 48-amp setup to charge at maximum speed. Let us look at the hardware required to do the job right.
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 7.9 hours |
| Range added per hour (Level 2) | about 33 miles |
| Full charge on a 120 V outlet | about 60 hours |
| Range added per hour (120 V) | about 4.3 miles |
| EPA rated range | 258 miles |
| Energy for a full charge | about 87.0 kWh at the wall |
Why 48 amps and not more
Your vehicle has a maximum onboard acceptance rate of 48 amps, which requires a 48-amp Level 2 charger to hit peak speeds. Feeding this car a larger unit yields zero benefit because the onboard charger limits current intake. Plugging into this correct amperage recovers 33 miles of range every hour. A full charge from empty takes 7.9 hours at this maximum rate. The EPA test protocol results in a slower 12 hours and 22 miles per hour because that testing does not always run at the car maximum AC rate.
What the install involves
You need a licensed sparky to pull heavy gauge copper wire and land a 60-amp breaker in your main panel. No household receptacle is rated for 48 amps, so the EVSE must be hardwired directly to the circuit. Ask your electrician to verify spare capacity in your breaker box before buying parts. Units like the Emporia 48A or Wallbox Pulsar Plus 48A fit this exact wiring specification.

Common questions
- Can I use a standard wall outlet?
- No. Level 1 charging on a standard household outlet gives you only 4.3 miles of range per hour and takes 60 hours for a full charge. You need a dedicated 60-amp circuit for fast Level 2 speeds.
- What connector does this car use?
- Your car uses a J1772 connector for AC Level 2 charging. Every non-Tesla EV sold in North America through 2024 uses this standard.
- Can I charge at Tesla stations?
- Yes, if you buy an adapter like the Lectron Tesla to J1772 Charging Adapter 80A. This lets your J1772 car plug into Tesla Destination Chargers and Wall Connectors.
- What if my garage layout is tight?
- Choose a compact unit like the Wallbox Pulsar Plus 48A. It fits small wall spaces while still delivering the full 48 amps your car accepts.
