What EV Charger Do You Need for a 2019 Tesla Model X?
Plugging in at 48 amps takes 9.9 hours to fill the 113.9 kWh battery from empty. That timeline easily fits standard overnight utility schedules. You need a 60 amp breaker and a hardwired supply to hit that speed. No plug-in outlet works for this load.
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 33 miles |
| Full charge on a 120 V outlet | about 79 hours |
| Range added per hour (120 V) | about 4.1 miles |
| EPA rated range | 325 miles |
| Energy for a full charge | about 113.9 kWh at the wall |
Why 48 amps and not more
Your car accepts up to 11.5 kW, which translates directly to a 48 amp draw on a Level 2 circuit. Buying a larger charging unit makes zero sense because the onboard charger cannot accept more power. Pushing fewer amps slows down the replenishment rate without saving money on the hardware. Hardwiring the Tesla Wall Connector delivers the maximum 33 miles of range per hour directly through the NACS connector.
What the install involves
A 48 amp continuous load demands heavy copper wire and a 60 amp breaker. Code rules prohibit standard receptacles at this amperage because outlets melt under sustained heat. Hardwiring eliminates the failure point of a plug and socket. Hire a licensed electrician to run the line from your panel to the garage wall.
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
- Can I plug this car into a standard wall outlet?
- Level 1 charging takes 79 hours for a full tank and adds only 4.1 miles of range per hour. It works for emergencies, but daily driving requires Level 2 equipment.
- Why does the EPA charge time show 12.0 hours?
- The EPA test protocol factors in charging losses and different test cycles rather than running strictly at the maximum 11.5 kW onboard limit. Real-world 48 amp hardware hits the full battery in 9.9 hours.
- Do I need a special adapter for non-Tesla chargers?
- The car uses a NACS connector. A J1772 adapter ships with the car for third-party Level 2 units.
- What charging gear should I buy?
- The Tesla Wall Connector matches the 48 amp maximum draw and hardwires directly with a 24.0 foot cable.
Other vehicles
Charging times derived from EPA data for the 2019 Tesla Model X (covering 2 EPA trim listings). Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
