What EV Charger Do You Need for a 2021 Tesla Model 3?
| Trim | Accepts | Charger | Breaker |
|---|---|---|---|
| Long Range / Performance | 11.5 kW / 48 A | 48 A | 60 A |
| RWD (Standard Range) | 7.7 kW / 32 A | 32 A | 40 A |
Forty-eight amps is the ceiling for the Long Range and Performance variants. The Rear-Wheel Drive variant pulls thirty-two amps. Your specific trim dictates the hardware you buy.
The numbers
| Maximum AC charging rate | 11.5 kW (48 A) on the fastest trim. See the table above for yours |
|---|---|
| Charge port | NACS |
| Full charge on Level 2 (fastest trim) | about 7.7 hours |
| Range added per hour (Level 2) (fastest trim) | about 46 miles |
| Full charge on a 120 V outlet | about 62 hours |
| Range added per hour (120 V) | about 5.7 miles |
| EPA rated range | 353 miles |
| Energy for a full charge | about 88.6 kWh at the wall |
Why 48 amps and not more
The onboard charger dictates your charging speed, not the size of the supply. Feeding forty-eight amps to the Long Range variant restores forty-six miles of range per hour. Hooking this car to a sixty-amp breaker fills the battery in seven point seven hours. Pumping more power past forty-eight amps does nothing because the onboard hardware caps the intake. Going smaller means longer overnight waits.
What the install involves
A sixty-amp breaker feeds a forty-eight-amp load safely. The National Electrical Code requires continuous loads to run at eighty percent capacity. Hardwiring is mandatory for forty-eight amps because no household receptacle handles that continuous draw. Hire a licensed electrician to run the heavy-gauge copper wiring and mount the unit directly to the wall. Do not attempt DIY installation on a sixty-amp circuit.
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.
These suit the Long Range / Performance trim at 48 A. If you have the RWD (Standard Range), a 32 A unit is all you need.
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 use a standard wall outlet?
- Level 1 charging on a standard household outlet delivers five point seven miles of range per hour. A full recharge takes sixty-two hours. You need a Level 2 setup for daily driving.
- What plug does the car use?
- Tesla vehicles use the NACS connector. Tesla sells native hardware, and third-party Level 2 units work using the included J1772 adapter.
- Why does the EPA charge time differ from the peak rate?
- The EPA test does not run at the car's peak AC rate for the entire cycle. Real-world charging at the maximum forty-eight amps hits a full battery much faster than the EPA estimate.
- Do I need a professional installation?
- Running a high-amperage circuit requires permits, load calculations, and heavy-gauge wire sizing. Call a licensed electrician to handle the breaker panel work.
Other vehicles
Charging times derived from EPA data for the 2021 Tesla Model 3 (covering 3 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.
