Does JuiceBox 40 work with Rivian R1T?

What works & limitations

• J1772 connector matches Rivian's standard charge port — no adapter required
• 9.6kW output adds approximately 28 miles of R1T range per charging hour
• JuiceBox app enables time-of-use scheduling to charge during off-peak utility rates
• Real-time energy monitoring and full session history in the Enel X Way app
• Compatible with R1T Standard and Max Pack (135kWh) battery configurations
• Amazon Alexa and Google Home integration for voice-triggered schedule changes
• Demand-response program support in participating utility regions
• 40A output is below R1T's 11.5kW AC ceiling — the vehicle can charge faster with a JuiceBox 48 or JuiceBox 80
• Rivian vehicle-level charging schedules set in the Rivian app are separate from JuiceBox app schedules — manage from one app to avoid conflicts
• Rivian R1T Max Pack is 135kWh usable; at 9.6kW the JuiceBox 40 takes approximately 14 hours from near-empty to full — overnight plus daytime charging may be needed for the largest battery option
• JuiceBox 40 requires a dedicated 50A circuit (40A continuous draw per NEC 80% rule); professional installation is strongly recommended
• For R1T owners wanting maximum Level 2 home charging speed, the JuiceBox 80 at 80A (19.2kW) is limited by the R1T's 11.5kW onboard charger — the JuiceBox 48 at 48A (11.52kW) is the closest match to the R1T's actual ceiling
• JuiceBox supports utility demand-response programs in regions including PG&E, ConEd, and others — the charger can automatically pause or reduce current during grid peak events in exchange for bill credits
