Rivian R1S
charging guide
The R1S is a 400-mile, three-row SUV with serious off-road hardware. Its huge battery makes 48-amp home charging the sensible minimum.
Charging at home
A 48-amp circuit adds about 28 miles per hour. On a 135 kWh pack, a 32-amp circuit adds only about 19 miles per hour, so the bigger circuit is worth it if your panel can take it. 2025 and newer NACS trucks need a J1772-to-NACS adapter to use the Rivian Wall Charger, or a native NACS wall unit.
How long does it take?
These estimates assume a 10–90% charge, 240 V AC and 90% efficiency. Cold weather, a cold battery or a shared circuit will slow things down.
| Circuit | Power | Range added | 10–90% time |
|---|---|---|---|
| 32 A | 7.68 kW | 19 mi/hr | 15h 38m |
| 40 A | 9.6 kW | 23 mi/hr | 12h 30m |
| 48 A | 11.5 kW | 28 mi/hr | 10h 26m |
Estimates use the car's 11.5 kW onboard charger. If your trim has a smaller unit, the 32 A row is the practical ceiling. Want your own numbers? Use the charging time calculator.
Can you use a Tesla Supercharger?
Rivian has Supercharger access. 2022–2024 R1S cars need Rivian's NACS-to-CCS1 adapter; 2025 and newer cars have a native NACS port. Peak DC power is about 220 kW.
Adapters you may need
- NACS-to-CCS1 adapter — Lets a CCS1 car charge at Tesla Superchargers
- J1772-to-NACS adapter — Lets a Tesla use J1772 chargers
What this car is best for
Best for families who need three rows, real off-road ability, and long range.
Frequently asked questions
Does the R1S have a NACS port?+
2025 and newer R1S vehicles have a native NACS port. Earlier cars use J1772/CCS1 and need Rivian's adapter for Tesla Superchargers.
Can I charge an R1S on a 32-amp circuit?+
Yes, but it adds only about 19 miles per hour. For a 135 kWh pack, 48 amps is a much better fit if your electrical panel allows it.
