What home charger does the Polestar 4 need?
| Model years | Trims | Charger | Breaker |
|---|---|---|---|
| 2025-2026 | all trims | 48 A | 60 A |
Get a 48 A charger and a 60 A breaker for the Polestar 4. Its onboard charger accepts 11.0 kW on AC in both the 2025 and 2026 models, single or dual motor.
Why 48 amps and not more
The Polestar 4 limits its own intake, so a charger above 48 A adds nothing but cost. A 40 A charger takes a 2026 from 31 miles of range per hour to 26. That is a modest loss, and for a driver who plugs in every night it may never be felt.
Charging time by model year
| Year | EPA range | Level 2, miles per hour | Level 2, empty to full | 120 V, miles per hour |
|---|---|---|---|---|
| 2026 | 255 to 310 mi | 31 | 9.9 h | 4.1 |
| 2025 | 272 to 300 mi | 30 | 10.1 h | 3.9 |
Level 2 figures assume a charger that supplies the car's full rate. Where a year shows a range, it spans that year's trims.
The 2025 and 2026 cars are close. The 2025 adds 30 miles of range per hour and takes 10.1 hours from empty, and the 2026 adds 31 and takes 9.9 hours. Range runs from 255 to 310 miles, and a used 2025 needs the same setup as a new 2026.
What it costs to charge at home
At the U.S. average residential rate of 18.19¢ per kWh, the 2026 Polestar 4 costs 6.4 to 8.0¢ a mile to charge at home. A full charge from empty comes to about $20, and 37 miles a day to about $72 to $90 a month. EPA measures energy use at the wall, so the energy lost while charging is already counted. Rates run from 12.36¢ in North Dakota to 46.28¢ in Hawaii, and the cost guide has every state.
What the install involves
Measure the distance from the panel to the parking spot before getting quotes. A long run needs more heavy copper and costs more. The charger is hardwired to a 60 A breaker, since no standard receptacle is rated for 48 A. Most areas also want a permit and an inspection for the new circuit.
- 48 A charger: 60 A breaker, hardwired, because no household receptacle is rated for a 48 A charger.
- Dryer outlet: a 4-prong NEMA 14-30 on a 30 A breaker can run a 24 A charger. That adds about 16 miles of range per hour to the 2026 Polestar 4, or 160 in a 10-hour night. What to check first.
- Charge port: J1772. From 2025 the industry is moving to the NACS port, and makers switch at different times. Some of these cars have a J1772 port and some have NACS with an adapter, so look at the port on your own car before choosing a charger's plug.
Chargers that fit the Polestar 4
Smallest adequate unit first. Every amp above what the car accepts is capacity it never uses.
Energy monitoring built in. Hardwire it for the full 48 A.
Compact unit, good for tight garages.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.
