What home charger does the Rivian R2 need?
| Model years | Trims | Charger | Breaker |
|---|---|---|---|
| 2027 | all trims | 48 A | 60 A |
The 2027 Rivian R2 takes a 48 A charger on a 60 A breaker. Its onboard charger accepts 11.5 kW on AC, and a 48 A unit supplies all of it.
Why 48 amps and not more
Nothing above 48 A helps, because the R2 caps its own intake. At 48 A it adds 36 miles of range per hour. A 40 A charger brings that to 30, a modest drop that most owners who charge nightly would hardly notice.
Charging time by model year
| Year | EPA range | Level 2, miles per hour | Level 2, empty to full | 120 V, miles per hour |
|---|---|---|---|---|
| 2027 | 307 to 330 mi | 36 | 9.2 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.
Every 2027 R2 shares the same onboard charger. Range runs from 307 to 330 miles, and a full charge from empty takes about 9.2 hours at 48 A.
What the install involves
Rivian built the R2 around a NACS charge port, so a NACS charger plugs straight in, and J1772 chargers work through an adapter. The circuit is a 60 A breaker with the charger hardwired, since no household receptacle is rated for 48 A. A load calculation up front tells you whether the panel can take it.
- 48 A charger: 60 A breaker, hardwired, because no household receptacle is rated for a 48 A charger.
- Charge port: 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 R2
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.
