What EV Charger Do You Need for a 2025 Polestar 2?
Standard household wiring provides a trickle, but your car demands a dedicated circuit to handle real power. Wall units can push higher amperages than this vehicle can ever draw. The car accepts 48 amps maximum, making any larger home unit a waste of money. You need a 48 amp Level 2 setup to match the onboard charger.
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 8.5 hours |
| Range added per hour (Level 2) | about 37 miles |
| Full charge on a 120 V outlet | about 65 hours |
| Range added per hour (120 V) | about 4.9 miles |
| EPA rated range | 314 miles |
| Energy for a full charge | about 93.1 kWh at the wall |
Why 48 amps and not more
The onboard charger dictates your charging speed, not the wall unit. Pushing more than 48 amps from the supply side accomplishes nothing because the car physically cannot draw it. Feeding the battery at the maximum rate puts 37 miles of range into the pack every hour. A full recharge takes 8.5 hours. Dropping down to a smaller breaker leaves you waiting much longer for a full battery.
What the install involves
A 48 amp continuous load requires a 60 amp breaker. Code prohibits using a standard 14-50 wall receptacle for a 48 amp draw because the continuous load melts household outlets. Hardwiring is mandatory for this exact amperage. Hire a licensed electrician to run heavy-gauge wire from your main panel directly to the charger.

Common questions
- Can I plug this car into a standard wall outlet?
- Yes, but Level 1 charging takes 65 hours to reach full capacity. You only recover 4.9 miles of range per hour on a standard 120-volt household plug. Install a Level 2 circuit for daily driving needs.
- What plug type does the car use?
- This 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's port before buying.
- Why do I need a 60 amp breaker for a 48 amp charger?
- Electrical code requires a 125 percent safety margin for continuous loads lasting over three hours. A 60 amp breaker protects the wiring while delivering the 48 amps your car requests.
- What is the difference between the 8.5 hour and 8.0 hour charge times?
- The 8.5 hour figure represents a full charge at the car's maximum Level 2 rate. The EPA test does not always run at the car's peak AC rate, which accounts for the slight difference.
Other vehicles
Charging times derived from EPA data for the 2025 Polestar 2 (covering 4 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.
