What EV Charger Do You Need for a 2023 Tesla Model X?
Your garage circuit might push out more power than this SUV can handle, or the car might demand more than a standard plug gives. The vehicle accepts up to 48 amps of current at 11.5 kilowatts. Level 2 charging takes 10.0 hours from empty to full. You need a 48 amp EVSE and a professional installation to hit that speed.
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
Matching the 48 amp onboard charger requires a 48 amp EVSE. Pumping more current into the port changes nothing because the vehicle limits intake. It draws 48 amps maximum, adding 35 miles of range per hour. Smaller chargers exist, but they slow down the refill process unnecessarily. Stick to the 48 amp rating for the fastest home turnaround.
What the install involves
A 48 amp continuous load demands a 60 amp breaker. Hardwiring is mandatory here since no household receptacle handles 48 amps safely. Hire an electrician to run heavy-gauge wire from the main panel to the mounting location. Do not attempt DIY work on a circuit of this size unless you hold a 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.
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 into a regular wall outlet?
- Level 1 charging on a standard household outlet takes 80 hours for a full charge. It adds 4.4 miles of range per hour. You will want a Level 2 setup for daily convenience.
- Why does the EPA charge time differ from the max rate?
- The EPA tests efficiency under specific laboratory conditions that do not always match peak output. The vehicle takes 10.0 hours at its maximum Level 11.5 kilowatt rate, while the EPA test runs 14.0 hours.
- What connector does the car use?
- The vehicle uses a NACS connector. Tesla includes a J1772 adapter in the box so you can plug into third-party Level 2 hardware.
- Do I have to buy the Tesla Wall Connector?
- Any unit supplying 48 amps with a hardwired connection works fine. The Tesla Wall Connector provides a native NACS plug and matches the maximum onboard charging rate.
