What EV Charger Do You Need for a 2025 Polestar 4?
A full Level 2 charge takes 10.1 hours. That easily covers an overnight turnaround for your daily driving. You need a 48 amp EVSE to hit this 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 10.1 hours |
| Range added per hour (Level 2) | about 30 miles |
| Full charge on a 120 V outlet | about 77 hours |
| Range added per hour (120 V) | about 3.9 miles |
| EPA rated range | 300 miles |
| Energy for a full charge | about 111.0 kWh at the wall |
Why 48 amps and not more
Your car accepts up to 48 amps of alternating current. Pushing 48 amps delivers 30 miles of range every single hour. Buying a larger charger will not speed this up because the onboard charger caps the draw at 11.0 kilowatts. A smaller unit only slows down your recovery time. Stick to the 48 amp ceiling to match what the vehicle handles.
What the install involves
You need a licensed electrician to pull a heavy circuit and land a 60 amp breaker in your panel. Never plug a 48 amp unit into a wall outlet because no household receptacle is rated for that continuous load. Hardwire the charger directly instead. The electrician must check your panel for spare capacity before starting the run.

Common questions
- Can I plug this car into a standard wall outlet?
- Level 1 charging from a standard outlet takes 77 hours for a full tank. It adds only 3.9 miles of range per hour. You will want a Level 2 setup for daily convenience.
- What connector does the car use?
- It uses a J1772 connector. Many units ship with a NACS port during the industry transition, but an adapter keeps older J1772 hardware fully functional. Confirm your port type before ordering.
- Why does the EPA charge time differ from the max rate?
- The EPA rated test takes 11.0 hours at 27 miles of range per hour. Real world results vary based on temperature and grid conditions.
- Do I need a hardwired connection?
- Yes. A 48 amp draw requires hardwiring because no standard household receptacle handles that current safely. Your electrician will wire the unit directly to the breaker.
Other vehicles
Charging times derived from EPA data for the 2025 Polestar 4 (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.
