What home charger does the Polestar 3 need?
| Model years | Trims | Charger | Breaker |
|---|---|---|---|
| 2025-2026 | all trims | 48 A | 60 A |
The Polestar 3 takes a 48 A charger on a 60 A breaker. Both the 2025 and 2026 models accept 11.0 kW on AC, so one charger covers either.
Why 48 amps and not more
This is a large SUV with a large battery, but the onboard charger still stops at 11.0 kW, so a bigger charger doesn't help. At 48 A a 2026 adds 26 to 29 miles of range per hour. A 40 A charger brings that to 22 to 24, which is noticeable on a vehicle with a battery this large.
Charging time by model year
| Year | EPA range | Level 2, miles per hour | Level 2, empty to full | 120 V, miles per hour |
|---|---|---|---|---|
| 2026 | 281 to 312 mi | 26 to 29 | 10.6 h | 3.5 to 3.8 |
| 2025 | 279 to 350 mi | 25 to 31 | 11.1 to 11.2 h | 3.3 to 4.1 |
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 cars take 11.1 to 11.2 hours to fill from empty, with up to 350 miles of range. The 2026 cars take 10.6 hours, with 281 to 312 miles. The charger itself is unchanged between those model years.
What the install involves
Hardwiring is the way to go for a charger that runs every night. It avoids wear on a receptacle, and no household receptacle is rated for 48 A in any case. The electrician lands the circuit on a 60 A breaker. Ask for the unit to be mounted where the cable reaches the port with the SUV parked normally.
- 48 A charger: 60 A breaker, hardwired, because no household receptacle is rated for a 48 A charger.
- 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 3
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.
