What EV Charger Do You Need for a 2021 Polestar 2?
A full charge takes 7.8 hours on a Level 2 setup. That timeline finishes easily overnight while you sleep. The car accepts up to 48 amps of current. You need a 60-amp circuit to hit that maximum 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 7.8 hours |
| Range added per hour (Level 2) | about 30 miles |
| Full charge on a 120 V outlet | about 59 hours |
| Range added per hour (120 V) | about 3.9 miles |
| EPA rated range | 233 miles |
| Energy for a full charge | about 85.4 kWh at the wall |
Why 48 amps and not more
Matching the vehicle onboard charger requires a 48-amp Level 2 supply. Pushing past that limit offers zero benefit because the car caps AC intake at 11.0 kilowatts. A smaller 32-amp circuit works fine if your panel lacks capacity, but recovery times stretch out longer. Buying a 50-amp or 48-amp EVSE lets you capture every kilowatt the hardware permits. Feed it the right current and daily replenishment takes care of itself.
What the install involves
A 48-amp continuous load demands a hardwired connection rather than a standard wall plug. Regulations prohibit wall receptacles for continuous loads of this size. You need a dedicated 60-amp circuit paired with heavy-gauge copper wiring. Hire a licensed electrician to run the line and mount the unit safely. Code requirements and panel loads mean DIY work here creates a serious fire hazard.

Common questions
- Can I plug this car into a standard wall outlet?
- Level 1 charging from a standard household outlet takes 59 hours for a full tank. You only gain 3.9 miles of range per hour that way. Daily commuting demands a proper Level 2 installation.
- What connector does the car use?
- The charge port accepts a standard J1772 plug. Every non-Tesla EV sold in North America through 2024 uses this exact connector for AC Level 2 charging.
- Why does the EPA charge time differ from the max rate?
- The EPA rates a full Level 2 charge at 8.0 hours rather than 7.8 hours. Government test cycles account for minor efficiency losses during power conversion.
- How many miles of range do I get per hour?
- A 48-amp Level 2 setup pumps about 30 miles of range into the battery every hour. That speed refills a completely depleted pack well before morning.
