What EV Charger Do You Need for a 2025 Subaru Solterra/Touring?
Thirty-two amps. That is the exact draw your car takes on Level 2 equipment. Buying a larger 48 amp or 80 amp home charger provides zero speed benefit because the internal hardware caps power at 6.6 kilowatts. You need a 40 amp breaker to feed this setup safely.
The numbers
| Maximum AC charging rate | 6.6 kW (32 A) |
|---|---|
| Charger size to buy | 32 A |
| Circuit breaker required | 40 A |
| Outlet / connection | NEMA 14-50 outlet on a 40 A breaker, or hardwired |
| Charge port | J1772 |
| Full charge on Level 2 | about 11.1 hours |
| Range added per hour (Level 2) | about 20 miles |
| Full charge on a 120 V outlet | about 51 hours |
| Range added per hour (120 V) | about 4.4 miles |
| EPA rated range | 222 miles |
| Energy for a full charge | about 73.3 kWh at the wall |
Why 32 amps and not more
The onboard charger dictates your charging ceiling, not the wall unit. Pumping more current into the vehicle does nothing because the car will ignore the excess capacity. Buying a bigger charger wastes money on hardware your car cannot use. Stick to the 32 amp target to match the factory limit. The battery holds 73.3 kilowatt-hours, taking 11.1 hours to reach full capacity from empty at maximum Level 2 speed.
What the install involves
Call a licensed electrician to pull a new circuit and land it on a 40 amp breaker in your panel. You can install a NEMA 14-50 outlet or hardwire the unit directly to the supply lines. The electrician must check your main service panel to confirm spare physical capacity exists before starting. Hardwiring removes a point of failure at the plug interface, though a proper industrial grade outlet works fine if installed correctly.

Common questions
- What connector does this car use?
- It uses a J1772 connector. Many 2025+ vehicles ship with a NACS port but include a J1772 adapter, so a J1772 home charger still works. Confirm your car's port before buying.
- How long does a full charge take on Level 2?
- A full charge takes 11.1 hours at maximum Level 2 speed. You will recover 20 miles of range for every hour plugged in.
- Can I use a standard wall outlet?
- Standard household outlets provide Level 1 charging at 4.4 miles per hour. A full charge on Level 1 takes 51 hours, making a 240 volt Level 2 setup necessary for daily driving.
- Do I need a bigger charger for future vehicles?
- Buying a 40 amp unit like the Grizzl-E Classic provides headroom for future vehicles that accept higher current. Your current Solterra will only draw 32 amps regardless of how much power the wall unit can supply.
