What home charger does the Polestar 2 need?
| Model years | Trims | Charger | Breaker |
|---|---|---|---|
| 2021-2025 | all trims | 48 A | 60 A |
The Polestar 2 takes a 48 A charger on a 60 A breaker. Every model year from 2021 through 2025, single or dual motor, accepts 11.0 kW on AC.
Why 48 amps and not more
The car caps AC charging at 11.0 kW, so a charger above 48 A is wasted. A 40 A charger costs some speed, bringing a 2025 from 30 to 37 miles of range per hour down to 25 to 31. For most commutes that slower rate still refills the day's driving overnight.
Charging time by model year
| Year | EPA range | Level 2, miles per hour | Level 2, empty to full | 120 V, miles per hour |
|---|---|---|---|---|
| 2025 | 254 to 314 mi | 30 to 37 | 8.5 h | 3.9 to 4.9 |
| 2024 | 247 to 320 mi | 31 to 38 | 7.9 to 8.5 h | 4.1 to 4.9 |
| 2023 | 247 to 270 mi | 31 to 35 | 7.7 to 8 h | 4 to 4.6 |
| 2022 | 249 to 270 mi | 35 | 7.7 h | 4.6 |
| 2021 | 233 mi | 30 | 7.8 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 Polestar 2 got more range over the years, from 233 miles in 2021 to as much as 320 in 2024, while the charger stayed the same. Full charges take 7.7 to 8.5 hours from empty, so a used early car and a new one need the same equipment.
What it costs to charge at home
At the U.S. average residential rate of 18.19¢ per kWh, the 2025 Polestar 2 costs 5.4 to 6.7¢ a mile to charge at home. A full charge from empty comes to about $17, and 37 miles a day to about $61 to $75 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
Expect a permit and an inspection for a new 240 V circuit. The electrician will fit a 60 A breaker and hardwire the charger, because no household receptacle is rated for a 48 A load. If the panel is short on room, a 40 A charger on a NEMA 14-50 outlet and a 50 A breaker is the usual fallback.
- 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 15 to 18 miles of range per hour to the 2025 Polestar 2, or 150 to 180 in a 10-hour night. What to check first.
- Charge port, 2021-2024: J1772. Every non-Tesla EV sold in North America through 2024 uses the J1772 connector for AC Level 2 charging.
- Charge port, 2025: 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 2
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.

Common questions
- Does a used 2021 Polestar 2 need a different charger from a 2025?
- No. Every year accepts 11.0 kW, so the same 48 A charger fits.
- How long does a Polestar 2 take to charge from empty?
- About 7.7 to 8.5 hours on a 48 A charger.
- Can a Polestar 2 use a NEMA 14-50 outlet?
- Yes, through a 40 A charger on a 50 A breaker. A 48 A charger must be hardwired.
- What charge port does the Polestar 2 use?
- The 2021 to 2024 cars use J1772. For 2025, check your own car, since makers are moving to NACS at different times.
