How long to charge a Rivian R1S at home
Typical trim (R1S Premium Long Range (20in AT)): 43.2 kWh/100 mi · EPA range 370 mi · on a 48 A (11.5 kW) charger about 27 mi of range per hour*
EPA lists a 240 V full-charge time of 15 h for this trim, which implies an average of roughly 10.7 kW (our estimate, = 160 kWh ÷ 15 h). Chargers well above that are unlikely to charge this car faster on AC; check the owner's manual for the onboard charger rating.
Range added by charger size (typical trim)
| Charger | Range per hour | Per 8-hour night | Empty to full EPA range |
|---|---|---|---|
| 12 A at 120 V (Level 1 cord) (1.4 kW) | 3 mi | 27 mi | 111.0 h |
| 16 A at 240 V (3.8 kW) | 9 mi | 71 mi | 41.6 h |
| 24 A at 240 V (5.8 kW) | 13 mi | 107 mi | 27.8 h |
| 32 A at 240 V (7.7 kW) | 18 mi | 142 mi | 20.8 h |
| 40 A at 240 V (9.6 kW) | 22 mi | 178 mi | 16.7 h |
| 48 A at 240 V (11.5 kW) | 27 mi | 213 mi | 13.9 h |
| 64 A at 240 V (15.4 kW) | 36 mi | 284 mi | 10.4 h |
| 80 A at 240 V (19.2 kW) | 44 mi | 356 mi | 8.3 h |
*Estimates: charger kW ÷ EPA kWh/100 mi × 100, assuming the car accepts that power. Charging tapers near 100% and is slower in the cold.

Source: fueleconomy.gov vehicle records (2026, 2027 model years). "Energy for full range" = kWh/100 mi × range ÷ 100, measured at the wall, so it includes charging losses and is not the battery size. Usable battery capacity is not in EPA data (data gap).
Will a bigger charger charge it faster? (per trim)
Times are empty to full EPA range. They are capped at the onboard charger rating only where EPA's own trim name states it. Otherwise they assume the car accepts the charger's full power, which may overstate the gain from 48 A and 80 A units.
