Rivian R1S Charging Time
A 2027 Rivian R1S takes about 14 hours to charge from empty to full on a 240-volt Level 2 charger, according to its EPA test, and 12 to 15 hours across the 2027 trims. On a standard 120-volt outlet it takes about 111 hours. A full charge puts about 160 kWh through the plug for 338 miles of range.

Cost to charge a Rivian R1S
A full charge from empty draws about 160 kWh from the wall. At 18 cents per kWh it costs about $28.80, and a 20% to 80% top-up about $17.28. The EPA rates the R1S Quad (22in UHP) at 47.3 kWh per 100 miles, which works out to 8.5 cents a mile. The US average home rate was 18.16 cents per kWh in August 2026 (EIA); the EV charging cost calculator takes your own rate.
Rivian R1S fast charging
DC fast charging bypasses the car's onboard charger and is far quicker, but the speed depends on each model's charging curve, which slows as the battery fills. That's why fast-charge times are quoted from 10% to 80%. The EPA doesn't test DC charging, so check Rivian's quoted figure for the R1S. The EV charging curve guide explains why it slows.
