What EV Charger Do You Need for a 2024 Tesla Model X?
Forty-eight amps is the maximum Level 2 draw your car handles. You need a 48-amp EVSE to hit the 11.5 kilowatt onboard limit. Plugging into anything smaller slows your refill rate down.
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 9.8 hours |
| Range added per hour (Level 2) | about 34 miles |
| Full charge on a 120 V outlet | about 78 hours |
| Range added per hour (120 V) | about 4.3 miles |
| EPA rated range | 335 miles |
| Energy for a full charge | about 112.6 kWh at the wall |
Why 48 amps and not more
The battery holds 112.6 kilowatt-hours, so you want the fastest home replenishment available. Matching the 48-amp maximum means a full tank takes 9.8 hours. Buying a larger charging unit makes zero difference because the onboard charger caps the intake anyway. Going with a smaller unit extends your overnight wait time.
What the install involves
This setup demands a 60-amp breaker to safely handle the continuous load. Hardwiring is mandatory here since standard household outlets cannot take 48 amps without melting. Hire a licensed electrician to run the heavy gauge wiring and mount the hardware directly to the wall. Do not attempt DIY installation on a circuit of this size.
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.

Common questions
- Can I plug this into a normal wall outlet?
- Level 1 charging from a standard household outlet delivers 4.3 miles of range per hour. A full recharge takes 78 hours this way.
- Why does the EPA charge time say 14 hours?
- The EPA test protocol calculates efficiency differently and does not run at the car's peak AC rate. Your actual home rate reaches 34 miles per hour.
- What connector does the car use?
- Your car uses the NACS connector natively. The Tesla Wall Connector matches this directly.
- Do I need an adapter for public chargers?
- A J1772 adapter ships with the car for third-party Level 2 units. You use it whenever you encounter non-Tesla hardware.
