What EV Charger Do You Need for a 2019 Tesla Model X 100D?
Plugging this battery into a 48 amp Level 2 setup takes 9.9 hours to reach full capacity from empty. That timeline easily fits standard overnight windows. You need a 48 amp EVSE to hit that speed, and yes, you need an electrician.
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 30 miles |
| Full charge on a 120 V outlet | about 79 hours |
| Range added per hour (120 V) | about 3.7 miles |
| EPA rated range | 295 miles |
| Energy for a full charge | about 114.1 kWh at the wall |
Why 48 amps and not more
The car accepts up to 48 amps through its onboard charger at 11.5 kW. Buying a larger charging unit wastes money because the vehicle limits incoming current anyway. A smaller unit drops the speed, yielding fewer miles per hour of charge than the 30 mph you get at 48 amps. The EPA test logs a slower 25 mph rate and a 12.0 hour charge time because standard testing protocols do not always push equipment to peak thermal limits. Stick to the 48 amp rating for the fastest home turnaround.
What the install involves
Feeding a 48 amp continuous load requires a 60 amp breaker. Code prohibits plug-in receptacles for this amperage due to heat risks, so the unit must be hardwired directly into the electrical supply. Hire a licensed electrician to run the heavy-gauge copper wiring and mount the hardware. They will pull a permit and verify your panel can handle the load.
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.

Common questions
- Can I plug this car into a standard wall outlet?
- You can plug into a standard household outlet for Level 1 charging, but it takes 79 hours to fill the battery from empty. That method only adds 3.7 miles of range per hour. You need Level 2 equipment for daily driving.
- What connector does the car use?
- The vehicle uses the NACS connector. Tesla models work natively with the Tesla Wall Connector. A J1772 adapter comes in the car for third-party Level 2 hardware.
- Do I need a hardwired charger or can I use a plug?
- A 48 amp EVSE must be hardwired because no household receptacle is rated for that continuous load. Hardwiring eliminates vulnerable plug connections. Your electrician will wire the unit directly to the breaker.
- Why does the EPA charge time differ from the max rate?
- The EPA rates a full charge at 12.0 hours, yielding 25 miles of range per hour. Peak onboard capacity finishes the job in 9.9 hours at 30 miles per hour. Standardized government testing accounts for this variance.
Other vehicles
Charging times derived from EPA data for the 2019 Tesla Model X 100D. Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
