Best Home EV Charger for the Rivian R1S (2024)
Like the R1T, the R1S accepts 11.5 kW AC into a very large pack — go straight to a 48 A charger on a 60 A circuit. Adventure-vehicle duty cycles (roof boxes, towing, cold weather) eat range, which makes overnight full-rate charging genuinely useful.
The Rivian R1S charges at up to 11.5 kW on AC through its J1772 port, so the ideal home charger delivers at least 48 A. The ranking below combines charge rate, connector fit, and standby efficiency across the ENERGY STAR certified chargers in our database; charge times are for the Rivian R1S's 135 kWh battery.

"Real rate" is the lower of the charger's output and the Rivian R1S's onboard AC limit — a bigger charger cannot exceed what the car accepts. Times assume the nameplate rate with no taper.
Frequently asked questions
What size home charger does the Rivian R1S need?
The Rivian R1S's onboard AC charger tops out at 11.5 kW (about 48 A at 240 V). A charger rated at 48 A or more fully saturates it — extra amps beyond that add no speed.
How long does the Rivian R1S take to charge at home?
From empty to full at its maximum 11.5 kW AC rate, the Rivian R1S's 135 kWh battery takes roughly 11.7 hours. Typical daily top-ups are much shorter.
Does the Rivian R1S need an adapter for home charging?
The Rivian R1S has a J1772 port, the standard for home AC chargers — most chargers plug in directly, while NACS chargers need an adapter.
