What EV Charger Do You Need for a 2026 Polestar 4?
You need a 48 amp Level 2 home charger to fill your battery at the car's maximum AC rate. The vehicle has a 108.5 kWh battery and accepts up to 11.0 kW. Internal hardware limits what the car can draw, so buying a larger charger gives zero benefit.
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 9.9 hours |
| Range added per hour (Level 2) | about 31 miles |
| Full charge on a 120 V outlet | about 75 hours |
| Range added per hour (120 V) | about 4.1 miles |
| EPA rated range | 310 miles |
| Energy for a full charge | about 108.5 kWh at the wall |
Why 48 amps and not more
The 2026 Polestar 4 maxes out at 48 amps on AC power. Feeding it fewer amps means longer wait times at your house. Supplying more amps changes nothing because the onboard charger caps the intake at 11.0 kW. Buying a 48 amp unit fills the 108.5 kWh pack from empty in 9.9 hours. You get 31 miles of range for every hour plugged into Level 2. The EPA test logs a slower 11.0 hours because federal test procedures account for charging efficiency losses and different voltage drops over long cycles.
What the install involves
A 48 amp draw requires a dedicated 60 amp breaker and heavy copper wiring. You must hardwire the charger directly into the electrical system because no household outlet handles 48 continuous amps safely. Have a licensed electrician evaluate your panel for spare capacity before buying hardware. They need to pull the correct gauge wire, land it on the new breaker, and mount the unit securely to a wall stud.

Common questions
- What plug does the charger use?
- A 48 amp EVSE must be hardwired. No household receptacle is rated for this continuous load.
- Can I use a standard wall outlet?
- Plugging into a regular 120 volt wall outlet takes 75 hours for a full charge. That yields 4.1 miles of range per hour.
- What connector does the car take?
- It uses a J1772 connector. This model year falls in the industry transition, so confirm your exact port before buying hardware.
- Will a 50 amp charger charge it faster?
- No. The car's onboard charger limits intake to 48 amps and 11.0 kW.
Other vehicles
Charging times derived from EPA data for the 2026 Polestar 4 (covering 3 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.
