What home charger does the Rivian R1S need?
| Model years | Trims | Charger | Breaker |
|---|---|---|---|
| 2022-2027 | all trims | 48 A | 60 A |
The Rivian R1S takes a 48 A charger on a 60 A breaker. Every R1S from 2022 through 2027 accepts 11.5 kW on AC.
Why 48 amps and not more
The R1S is a heavy SUV with a very large battery, so even at 48 A it adds only about 29 miles of range per hour on a 2027. A 40 A charger drops that to 24. A charger above 48 A adds nothing, since the vehicle caps its own intake.
Charging time by model year
| Year | EPA range | Level 2, miles per hour | Level 2, empty to full | 120 V, miles per hour |
|---|---|---|---|---|
| 2027 | 289 to 410 mi | 29 | 14.2 h | 3.6 |
| 2026 | 258 to 410 mi | 29 | 14.2 h | 3.6 |
| 2025 | 258 to 410 mi | 29 | 14.2 h | 3.6 |
| 2024 | 255 to 400 mi | 22 to 28 | 12.4 to 14.2 h | 2.8 to 3.5 |
| 2023 | 274 to 352 mi | 27 | 13.2 h | 3.3 |
| 2022 | 316 mi | 24 | 13.4 h | 3 |
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.
Long charge times come with the big battery. A 2025 to 2027 R1S takes about 14.2 hours to fill from empty, with up to 410 miles of range. The 2022 launch model took 13.4 hours, and the 2024 lineup ranges from 12.4 to 14.2 hours depending on the battery.
What the install involves
Because a full charge takes most of a day, plugging in every night matters more with the R1S than with smaller cars. The electrician fits a 60 A breaker and hardwires the charger, since no household receptacle is rated for 48 A. A permit and inspection are standard.
- 48 A charger: 60 A breaker, hardwired, because no household receptacle is rated for a 48 A charger.
- Charge port, 2022-2024: J1772. Every non-Tesla EV sold in North America through 2024 uses the J1772 connector for AC Level 2 charging.
- Charge port, 2025-2027: 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 Rivian R1S
Smallest adequate unit first. Every amp above what the car accepts is capacity it never uses.
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.
