What EV Charger Do You Need for a 2019 Tesla Model X P100D?
Installing a sixty-amp charger for this car is a waste of money because the onboard hardware caps intake at forty-eight amps. Buying anything larger pays for capacity the vehicle cannot accept. Read on to learn the exact setup needed for home charging.
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 9.9 hours |
| Range added per hour (Level 2) | about 29 miles |
| Full charge on a 120 V outlet | about 79 hours |
| Range added per hour (120 V) | about 3.6 miles |
| EPA rated range | 289 miles |
| Energy for a full charge | about 114.3 kWh at the wall |
Why 48 amps and not more
The Model X P100D draws forty-eight amps maximum on alternating current. Feeding it more power yields no speed gain because the onboard charger acts as a strict bottleneck. A forty-eight amp supply replenishes twenty-nine miles of range per hour. Going smaller drops charging speed unnecessarily. The 114.3 kWh battery pack needs 9.9 hours to reach full capacity at this peak rate.
What the install involves
Powering this equipment demands a sixty-amp circuit breaker paired with heavy-gauge wiring. A forty-eight amp continuous load exceeds the rating of any standard wall receptacle. Hardwiring the unit directly to the electrical panel prevents thermal damage at the terminals. Hire a licensed electrician for this work to verify the home service panel can handle the load safely.
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.
Native NACS plug, no adapter needed.
Dual plug: works with NACS and J1772 cars.
Tesla's own unit. Native NACS, hardwire only.

Common questions
- Do I need a professional electrician to install the home equipment?
- Yes. Hardwiring a forty-eight amp load requires running thick copper wire and installing a sixty-amp breaker in your service panel.
- What connector does this vehicle use?
- It uses the NACS plug native to Tesla vehicles. A J1772 adapter also ships with the car for third-party Level 2 units.
- How long does a standard wall outlet take?
- Plugging into a regular household outlet delivers only 3.6 miles of range per hour. A full charge takes seventy-nine hours this way.
- Why does the EPA charge time differ from the peak rate?
- The EPA test time of 12.0 hours reflects standard test cycles that do not always run at the car's absolute peak AC rate.
Other vehicles
Charging times derived from EPA data for the 2019 Tesla Model X P100D. Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
