What home charger does the Lexus RZ need?
| Model years | Trims | Charger | Breaker |
|---|---|---|---|
| 2026 | all trims | 48 A | 60 A |
| 2023-2025 | all trims | 32 A | 40 A |
It depends on the year. A 2023 to 2025 Lexus RZ has a 6.6 kW onboard charger and needs only a 32 A charger on a 40 A breaker. The updated 2026 RZ accepts 11.0 kW and takes 48 A on a 60 A breaker.
Why the amperage matters
An older RZ stops drawing at 32 A, so a larger charger won't help it. The 2026 car is a different story: it adds 31 to 41 miles of range per hour at 48 A and 26 to 34 on a 40 A unit.
Charging time by model year
| Year | EPA range | Level 2, miles per hour | Level 2, empty to full | 120 V, miles per hour |
|---|---|---|---|---|
| 2026 | 228 to 301 mi | 31 to 41 | 7.3 to 7.4 h | 4.1 to 5.4 |
| 2025 | 196 to 266 mi | 21 to 25 | 10.3 to 10.8 h | 4.6 to 5.4 |
| 2024 | 196 to 266 mi | 21 to 24 | 10.4 to 10.9 h | 4.6 to 5.3 |
| 2023 | 196 to 220 mi | 21 | 10.7 h | 4.5 |
Level 2 figures assume a charger that supplies the car's full rate. Where a year shows a range, it spans that year's trims.
The 2026 update made a big difference at home. The 2023 to 2025 cars add 21 to 25 miles of range per hour and need 10.3 to 10.9 hours from empty. The 2026 car fills in 7.3 to 7.4 hours with up to 301 miles of range.
What the install involves
An older RZ is an easy install: a 32 A charger on a 40 A breaker, plugged into a NEMA 14-50 outlet or hardwired. A 2026 needs a hardwired 48 A charger on a 60 A breaker, so have the panel checked first. If you plan to trade up, wiring for 48 A now avoids redoing the job.
- 48 A charger: 60 A breaker, hardwired, because no household receptacle is rated for a 48 A charger.
- 32 A charger: 40 A breaker, NEMA 14-50 outlet on a 40 A breaker, or hardwired.
- Charge port, 2023-2024: J1772. Every non-Tesla EV sold in North America through 2024 uses the J1772 connector for AC Level 2 charging.
- Charge port, 2025-2026: J1772. From 2025 the industry is moving to the NACS port, and makers switch at different times. Some of these cars have a J1772 port and some have NACS with an adapter, so look at the port on your own car before choosing a charger's plug.
Chargers that fit the Lexus RZ
Smallest adequate unit first. Every amp above what the car accepts is capacity it never uses.
48 A, for the 2026 RZ all trims
Energy monitoring built in. Hardwire it for the full 48 A.
Compact unit, good for tight garages.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.
32 A, for the 2023-2025 RZ all trims
No home unit in this list is built at exactly 32 A, so these are the smallest that cover it. The car draws only what it can take.
App scheduling and adjustable current from 16 A to 40 A.
Plugs into an existing 14-50 outlet, no hardwiring.
Rugged metal enclosure, built for outdoor use.

Common questions
- Does a used 2024 Lexus RZ need a different charger from a 2026?
- It only uses 32 A, while the 2026 uses 48 A. A 48 A charger works for both, but the 2024 charges no faster on it.
- How long does a Lexus RZ take to charge from empty?
- About 10.3 to 10.9 hours for a 2023 to 2025 car and 7.3 to 7.4 hours for a 2026.
- Can a Lexus RZ use a NEMA 14-50 outlet?
- Yes. A 2023 to 2025 car works well with a 32 A plug-in charger, and a 2026 with a 40 A plug-in unit on a 50 A breaker.
- How much does a 120 V outlet add to a Lexus RZ?
- About 4.1 to 5.4 miles of range per hour.
