What EV Charger Do You Need for a 2027 Subaru Uncharted?
Many buyers waste money on an oversized 80 amp charger that your car cannot even use. Your Subaru Uncharted accepts a maximum of 48 amps on Level 2 equipment. Buying anything larger adds cost to your hardware without speeding up your daily charge time. You need a 48 amp Level 2 setup to hit the peak rate.
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 7.2 hours |
| Range added per hour (Level 2) | about 43 miles |
| Full charge on a 120 V outlet | about 55 hours |
| Range added per hour (120 V) | about 5.6 miles |
| EPA rated range | 308 miles |
| Energy for a full charge | about 79.0 kWh at the wall |
Why 48 amps and not more
Your car has an onboard charger rated at 11.0 kW. Matching this ceiling means feeding it 48 amps of current. Pumping more power from a larger unit does zero good because the car regulates its own intake. Any extra capacity on a bigger breaker sits idle. Stick to the 48 amp ceiling.
What the install involves
You need a professional to pull a heavy circuit and land a 60 amp breaker in your electrical panel. This setup requires hardwiring because no household receptacle is rated for 48 amps. A licensed electrician must verify your panel has spare capacity before tying in the new line. Do not attempt a DIY install on this amperage.

Common questions
- How long does a full charge take?
- Plugging into a 48 amp Level 2 charger takes 7.2 hours to fill the 79.0 kWh battery. The EPA test estimates 8.0 hours because that standard does not always run at the car's peak AC rate.
- What kind of plug does it use?
- This car uses a J1772 connector. This model year falls in the industry's NACS transition. 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.
- Can I use a standard wall outlet?
- Level 1 charging on a standard household outlet takes 55 hours for a full fill. That speed yields only 5.6 miles of range per hour. You will want a dedicated Level 2 circuit for normal driving.
- What charging speeds should I expect?
- Your peak Level 2 rate adds 43 miles of range per hour. The EPA rating calculates to 38 miles per hour under test conditions. Both rates replenish the 308 mile total range overnight.
