What EV Charger Do You Need for a 2022 Tesla Model X?
You need a 48 amp Level 2 home charging setup to pull the maximum AC rate this vehicle accepts. The onboard charger limits AC input to 11.5 kW. Buying a larger charging unit wastes money because the car cannot draw more power.
The numbers
| Maximum AC charging rate | 11.5 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 | NACS |
| Full charge on Level 2 | about 10.0 hours |
| Range added per hour (Level 2) | about 35 miles |
| Full charge on a 120 V outlet | about 80 hours |
| Range added per hour (120 V) | about 4.4 miles |
| EPA rated range | 348 miles |
| Energy for a full charge | about 115.1 kWh at the wall |
Why 48 amps and not more
The onboard hardware tops out at 48 amps. Pumping more than 48 amps into the car changes nothing. Extra capacity at the wall sits unused. The 115.1 kWh battery pack fills in 10.0 hours at this peak rate. Every hour plugged into a Level 2 source adds 35 miles of range. The EPA test protocol calculates a slower 14.0 hour recovery time because federal testing includes vehicle standby losses and charging inefficiencies not reflected in raw maximum output math.
What the install involves
A 48 amp continuous load demands a 60 amp breaker. Local electrical codes require hardwiring for any circuit exceeding 40 amps. No standard household receptacle handles a 48 amp draw safely. Hire a licensed electrician to run heavy gauge copper wiring from your panel to the charging location. Do not attempt DIY installation on a 60 amp circuit unless you hold a current electrical license.
Chargers that match this car
Your car has a NACS port. The NACS units below plug straight in; any J1772 unit works with the adapter supplied with the car.

Common questions
- Can I use a regular wall outlet?
- Level 1 charging uses a standard 120-volt household outlet. That method takes 80 hours to fill the battery from empty and adds only 4.4 miles of range per hour.
- What plug does the car use?
- Tesla vehicles use the NACS connector. Tesla's own Wall Connector is native, and a J1772 adapter ships with the car for third-party Level 2 units.
- Why is the EPA charge time slower than the max rate?
- The EPA-rated Level 2 charge time takes 14.0 hours at 25 miles per hour. Federal testing accounts for thermal management overhead and energy lost as heat during the conversion process.
- What is the car's efficiency rating?
- The vehicle consumes 33.1 kWh per 100 miles driven. That efficiency level yields 102 MPGe in combined driving with a total EPA range of 348 miles.
Other vehicles
Charging times derived from EPA data for the 2022 Tesla Model X. Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
