| Charge port | J1772 |
| Full charge on Level 2 | about 10.3 hours |
| Range added per hour (Level 2) | about 33 miles |
| Full charge on a 120 V outlet | about 82 hours |

Why 48 amps and not more
Your SUV handles up to 48 amps of alternating current. Buying a bigger 80 amp unit wastes money because the onboard charger cannot draw faster. Feeding it fewer amps slows down your overnight turnaround time for no good reason. Matching the vehicle limit gives you the fastest possible home charging speed. The battery capacity sits at 118.0 kWh, so you need this capacity to refill overnight.
What the install involves
You need a 60 amp breaker installed in your main panel. Hardwiring is mandatory for a 48 amp draw because no household receptacle handles that load safely. Have an electrician pull heavy gauge copper wire from the panel to the garage wall. Ask them to verify your breaker box has spare capacity before they start the job.

Common questions
- Can I use a standard wall outlet?
- Level 1 charging on a standard household outlet gives you 4.1 miles per hour. A full recharge takes 82 hours, which is far too slow for daily driving.
- What connector does this car use?
- This model features a J1772 connector. Many units ship with a NACS port and include an adapter, so check your specific vehicle port before ordering equipment.
- What is the EPA charging time?
- The EPA rating requires 11.2 hours at 30 miles per hour. Standard testing protocols vary slightly from real world peak rates.
- Will a 50 amp charger work?
- Units like the ChargePoint Home Flex cap your draw or adjust down to safe limits. Your car peaks at 48 amps, so stick to that target.
