With a Level 2 charger matched to the Rivian R1S's 11.5kW onboard charger, you can expect a full charge (10-100%) in about 10.6 hours. A standard 120V outlet (Level 1) would take significantly longer.

Yes, but it's very slow. A Level 1 charger (standard 120V outlet) delivers about 1.4kW, which would take roughly 96 hours for a full charge of the Rivian R1S's 135kWh battery. A Level 2 charger is highly recommended.
