Best EV Charger for Rivian R1T/R1S: 3 Top Picks in 2026

The R1T and R1S share the same charging architecture. Here are the key numbers:

• Onboard charger: 11.5 kW (48 amps at 240V) — this is the maximum AC charging speed for both R1T and R1S
• Charge port: NACS on 2025+ models. Earlier models use CCS1 for DC fast charging and J1772 for Level 2 AC.
• Charging speed at 48A: Approximately 25–30 miles of range per hour (lower mi/hr than sedans due to higher vehicle weight and consumption)
• Charging speed at 32A: Approximately 16–20 miles of range per hour
• Battery sizes: 75 kWh (Standard), 105 kWh (Large), or 135 kWh (Max)
• 10% to 80% charge time at 48A: About 4.5 hours (Standard), 6.5 hours (Large), or 8 hours (Max pack)

Key insight for Rivian owners: because the R1T and R1S are heavy vehicles with larger batteries, they consume more energy per mile than sedans. A 48-amp charger still provides full-speed charging, but the miles-per-hour rate is lower than, say, a Tesla Model 3. For the Max pack, overnight charging at 48A covers a 10–80% charge comfortably.

Pick 1: Grizzl-E Classic — $300

Best for: Rivian owners who want rugged, outdoor-ready charging.

The Grizzl-E Classic is the perfect match for the Rivian ethos — built tough, no frills, gets the job done in any condition. This Canadian-made charger has a NEMA 4 rating that handles rain, snow, dust, and temperature extremes from -30°C to 50°C. If your Rivian lives outside, your charger can too.

At 40A, the Grizzl-E does not quite max out the Rivian's 48A capacity, delivering about 9.6 kW vs the theoretical 11.5 kW maximum. In practice, this means about 25 miles of range per hour versus 30. For overnight charging, the difference is negligible — the Large pack charges 10–80% in about 7.5 hours vs 6.5 hours at full speed.

No app, no Wi-Fi, no Bluetooth. Just a plug-and-charge workhorse with a thick 24-foot cable that handles rough use. For the price, nothing else comes close on durability.

• Price: $300
• Max amperage: 40A
• Connector: J1772
• Cable length: 24 ft
• Weather rating: NEMA 4 (fully weatherproof)
• Circuit required: 50A dedicated

Pick 2: Tesla Wall Connector — $475

Best for: 2025+ Rivian owners who also own a Tesla or want native NACS.

The Tesla Wall Connector delivers 48 amps through a NACS connector, making it a natural fit for 2025+ Rivian models that adopted NACS. Plug in directly, no adapter needed. If your household also has a Tesla, one Wall Connector serves both vehicles seamlessly.

At 48A (11.5 kW), the Wall Connector fully utilizes the Rivian's onboard charger — you get maximum home charging speed. The 24-foot cable reaches comfortably around the R1T's large footprint, and the slim wall-mount design takes minimal space in your garage.

The trade-off: no energy monitoring, basic app experience (through Tesla app only), and pre-2025 Rivian owners with J1772 ports will need an adapter. If you need robust smart features, look at our other picks.

• Price: $475
• Max amperage: 48A
• Connector: NACS
• Cable length: 24 ft
• Weather rating: NEMA 3R (indoor/outdoor)
• Circuit required: 60A dedicated

Pick 3: Emporia Smart — $299

Best for: Rivian owners who want smart features at the lowest price.

The Emporia Smart packs Wi-Fi, energy monitoring, and a polished scheduling app into a $299 package — the cheapest smart charger worth recommending. It delivers 48 amps (11.5 kW), fully maxing out the Rivian's onboard charger at the same speed as the $475 Tesla Wall Connector.

The Emporia app tracks energy per session, estimates cost based on your utility rate, and lets you schedule charging for off-peak hours. If you are on a time-of-use plan, this can save significant money — especially with the Rivian's larger battery drawing more energy. Integration with Emporia's home energy monitor gives you whole-house visibility.

NEMA 4 weatherproofing means outdoor installation is no problem. The 24-foot J1772 cable works with pre-2025 Rivians directly, and 2025+ NACS models can use a J1772-to-NACS adapter.

• Price: $299
• Max amperage: 48A
• Connector: J1772
• Cable length: 24 ft
• Weather rating: NEMA 4 (fully weatherproof)
• Circuit required: 60A dedicated

The Tesla Wall Connector and Emporia Smart both deliver the full 48A to max out the Rivian's onboard charger. The Grizzl-E at 40A is slightly slower but makes up for it with unmatched weather resistance and durability. For the Rivian's large battery packs, all three provide comfortable overnight charging.

Rivian owners have specific needs that guided our selection. Here is what mattered most:

• Outdoor durability: Many Rivians park outside or in open garages. We prioritized chargers with strong weather ratings — two of our three picks are NEMA 4 (fully weatherproof), and all handle outdoor installation.
• NACS and J1772 coverage: With 2025+ Rivians using NACS and earlier models on J1772, we ensured our picks cover both connector types — either natively or via affordable adapters.
• Value-oriented: Rivian owners already made a significant vehicle purchase. We focused on chargers that deliver maximum speed without premium pricing — two of our picks are under $300.
• Overnight-capable for large packs: The Rivian Max pack is 135 kWh. We verified each charger can handle a 10–80% charge within a reasonable overnight window (8–10 hours max).
