What EV Charger Do You Need for a 2023 Lexus RZ 450e?
A full charge takes 10.7 hours on Level 2 equipment. That means standard overnight plug-ins finish the job before morning. You need a 32 A charger to hit this speed. The car will draw no faster.

|---|---|
| Charger size to buy | 32 A |

| Outlet / connection | NEMA 14-50 outlet on a 40 A breaker, or hardwired |
| Charge port | J1772 |
| Full charge on Level 2 | about 10.7 hours |
| Range added per hour (Level 2) | about 21 miles |
| Full charge on a 120 V outlet | about 49 hours |
| Range added per hour (120 V) | about 4.5 miles |
| EPA rated range | 220 miles |
| Energy for a full charge | about 70.4 kWh at the wall |
Why 32 amps and not more
The onboard charger maxes out at 32 amps. Buying a larger unit gets you nothing extra. The vehicle cannot process the extra current. Stick to a 32 A supply and match the recommended specs. Going bigger wastes money on hardware the car ignores.
What the install involves
Call a licensed sparky to pull a dedicated line. They need to land a 40 A breaker in the panel. The circuit feeds either a NEMA 14-50 outlet or a hardwired unit. Have them verify your panel has spare capacity first. Do not skip this step.

Common questions
- What plug type does the car use?
- It uses a J1772 connector. Every non-Tesla EV sold in North America through 2024 uses the J1772 connector for AC Level 2 charging.
- How fast does Level 1 charge work?
- A standard wall outlet takes 49 hours for a full tank. You get 4.5 miles of range per hour. That speed only works for low daily mileage.
- Can I use Tesla destination chargers?
- Yes, if you buy an adapter. The Lectron Tesla to J1772 Charging Adapter 80A lets a J1772 car use Tesla Destination Chargers and Wall Connectors.
- What is the EPA charge time?
- The EPA rated Level 2 charge time is 10.0 hours. This test does not always run at the car's peak AC rate, which explains the minor difference from the 10.7 hour maximum rate.
