Rivian home charger guide: J1772 or NACS?
By ReferCharge. Updated 2026-08-13.
Match the wall connector to the charge port: use J1772 for a 2022–2025 R1T or R1S and NACS for a 2026+ vehicle. Rivian identifies those model-year groups on its charging page. An adapter can preserve an existing installation, but a new installation is simplest when the cable matches the vehicle.

Buy J1772

Hardwired or NEMA 14-50?
Hardwired
Choose hardwired when the electrician is installing a dedicated wall unit and the desired output or site plan calls for it. The Lectron NEXUS listing below is a hardwired product; its maker page states that installation type.
NEMA 14-50 plug-in
Choose plug-in when a correctly installed NEMA 14-50 receptacle is part of the plan and the charger's configured current matches that circuit. We do not currently list a plug-in unit we have been able to source a clear installation manual for, so the only charger below is the hardwired option. Maker source.
