Understanding Rivian Accessories: A Clear Guide

Picking up an R1T or R1S — or planning to — means deciding which accessories you actually need. The lineup can be overwhelming. This guide focuses on daily driving and charging routines. You’ll get checklists, trade-offs, and common mistakes so you don’t waste money.

What You Need Before Buying Accessories

Before you browse Rivian’s shop or third-party sites, gather this information:

• Your model year and trim – Crossbars fit both models, but the cargo rail system and tonneau attachment points changed in 2023+. Verify your VIN with Rivian’s compatibility tool.
• Home electrical panel specs – A 48-amp Level 2 charger requires a 60-amp breaker and typically a 200-amp main panel. Get a photo of your panel label or an electrician’s quote before ordering.
• Driving mileage and usage – Daily commute under 30 miles? You might get by with the portable charger. Longer trips or frequent towing? Plan for a wall charger.
• Local charging network coverage – Check PlugShare for CCS station density along your typical routes. This determines if you need a NACS adapter.

Preparation checklist:

• [ ] Confirm vehicle model year and VIN
• [ ] Photograph your electrical panel (main breaker rating, available slots)
• [ ] Note average daily miles driven
• [ ] Identify 2–3 frequent road-trip destinations and CCS availability

How to Choose Your Accessories in Order

Use this step-by-step sequence to avoid buying the wrong gear first.

Step 1: Secure Your Charging Setup

Your charging solution is the most critical purchase. Decide between:

• Rivian Wall Charger (Level 2) – Adds ~16 miles of range per hour. Requires a 60-amp breaker and professional installation. If your panel needs an upgrade, budget $1,000–2,000 extra.
• Portable charger (included) – At 120V, adds only ~3 miles per hour. Fine for occasional top-ups, not daily driving.
• NACS adapter – Only needed if you’ll use Tesla Superchargers. Rivian sells the adapter separately for 2023 models; 2024+ includes it.

Decision rule: If you drive more than 30 miles daily, buy the wall charger first. If you mostly charge at work or rely on public stations, skip it and get the adapter.

Step 2: Protect the Interior

Rivian’s all-weather floor mats ($225 set) are the safest bet for full coverage. Third-party mats (e.g., WeatherTech) can be cheaper but sometimes miss rear under-seat areas on the R1S.

Trade-off: If you carry kids, pets, or muddy gear, buy the rubber mats immediately. Carpet mats stain and are hard to clean.

Step 3: Evaluate Exterior Needs

List what you carry: bikes, cargo boxes, kayaks, spare tire. Then choose:

• Crossbars – Support 220 lbs. Reduce highway range by 5–8% when installed. Remove them when not in use.
• Tonneau cover (R1T only) – The manual roll-up is currently the only official option. Skip the powered cover until Rivian resolves durability issues.
• Spare tire carrier – Neither R1T nor R1S comes with a spare. If you go >50 miles from a tire shop, buy the spare + carrier. Otherwise, a repair kit and compressor suffice.

Warning: The spare weighs ~70 lbs and reduces payload. Check your payload sticker before adding it.

Step 4: Confirm Compatibility and Warranty

Before clicking “buy,” check:

• Official Rivian accessories have a 1‑year / 12,000‑mile separate warranty. Third‑party electrical parts can void your vehicle warranty for related issues.
• Non‑Rivian chargers must be UL‑listed. UL certification includes overdischarge, short circuit, crush, and temperature cycling tests — critical for home safety.

Rule of thumb: Buy Rivian for anything electrical (charging, lighting, power). Buy third‑party for non‑critical items (aesthetic mats, bed liners) if you accept minor fit risk.

Essential Charging Accessories

Rivian Wall Charger (Level 2)

• Specs: 48 amps, 60-amp circuit required, Wi‑Fi enabled, weather-resistant.
• Pros: Fast charging (16 mi/hr), app scheduling, OTA firmware updates.
• Cons: ~$900 plus electrician fees; panel upgrade may add $500–1,500.

Rivian Portable Charger

• Specs: Includes NEMA 14‑50 (240V) and 5‑15 (120V) adapters, 18‑ft cable.
• Pros: Works at RV parks, no extra cost.
• Cons: At 120V, 10% to 80% charge on an R1S takes over 72 hours. Short cable may not reach outlets in some garages.

NACS (Tesla) Adapter

• Availability: Included on 2024+ models; sold separately for 2023 models.
• When to buy: If your frequent road‑trip routes have few CCS stations but many Superchargers. Otherwise, skip it.

Interior and Cargo Accessories

Cargo Dividers and Netting

The R1T gear tunnel has a hidden rail system. Rivian’s gear tunnel divider ($150) separates wet gear from dry luggage — handy after a surf session or rain. The cargo net ($60) secures loose bags. Using the divider keeps a muddy mountain bike bag separate from a clean suitcase on a week‑long trip.

Spare Tire and Carrier

Full‑size spare with carrier: ~$800 from Rivian. Weighs ~70 lbs. If you mostly drive paved roads, a repair kit and air compressor are lighter and cheaper. For off‑road or remote areas, the spare is essential.

Exterior and Utility Accessories

Crossbars and Roof Rack

Lock to the roof rails; support 220 lbs. Useful for bikes, cargo boxes, or kayaks. Range impact: 5–8% loss at highway speed. Remove when not in use.

Tonneau Cover (R1T only)

Rivian’s powered tonneau was recalled due to durability issues. The manual roll‑up is the only official option now. Third‑party manual covers (e.g., Truck Covers USA) fit well but may affect warranty on the bed system.

Current guidance: Skip the powered cover until Rivian redesigns it. If you need weather protection, buy the official manual cover or a third‑party option — just check owner forums for fitment reports.

Front-Facing Light Bar (Off‑road)

$2,000 official accessory, 20,000 lumens. Useful only if you off‑road at night. Common mistake: Overloading the accessory bar. The stock 12V system can handle the light bar or a winch, but not both simultaneously. Check total wattage before adding electrical accessories.

Buying Advice: Official vs. Third‑Party

Accessory Category	Official Rivian	Third‑Party
Charging equipment	✅ UL‑listed, warranty	❌ Risk of fire / voided warranty
Floor mats	✅ Perfect fit	✅ Cheaper, but check reviews
Tonneau cover	⚠️ Manual only for now	✅ More options, but warranty risk
Roof crossbars	✅ Aerodynamic, lock	✅ Usually cheaper, may whistle at speed
Spare tire carrier	✅ Integrated mount	❌ Few options; custom fabrication often needed

Verification and Common Mistakes

After installing your first accessory, confirm it works correctly before moving on.

Verification Check: Wall Charger

Plug in your Rivian and open the mobile app. The charging screen should show the expected rate (e.g., 16 mi/hr on a 48‑amp connection). If the rate is lower (e.g., 3 mi/hr), the charger may be on a reduced circuit or the portable charger was used by mistake.

Verification Check: Floor Mats

Sit in all rows and press each pedal fully. The mat should not slide or interfere. If it does, remove and re‑seat or return. For third‑party mats, check that the driver‑side dead pedal area is fully covered. Some aftermarket mats leave a gap.

Common Mistakes to Avoid

1. Buying a Level 2 charger before checking your electrical panel – You may need a 200‑amp service. Get an electrician’s quote first. Panel upgrades can cost $1,000–2,000.

2. Assuming the portable charger works for daily driving – At 120V, it takes 3–4 days to fully recharge an R1S. Not practical for daily commutes over 30 miles.

3. Forgetting the spare tire – Many first‑time buyers don’t realize the Rivian ships without one. If you drive remote routes, you’ll regret it.

4. Overloading the bed power outlet – The R1T’s 110V outlet is limited to 400W continuous. Running a power tool and a cooler simultaneously can trip it. Use a separate inverter for higher loads.

5. Installing electrical accessories without checking total wattage – Adding a light bar plus a winch can exceed the 12V system’s capacity. Check the combined current draw and stay below the fuse rating.

FAQ

Do I need a wall charger if I have the portable charger?

If you drive less than 30 miles a day and can charge overnight, the portable charger on 120V may suffice. For most daily drivers, a Level 2 wall charger pays for itself in convenience within a month.

Can I use a Tesla charging cable with my Rivian?

Yes, with the NACS adapter sold by Rivian. Without it, Tesla cables won’t physically connect or communicate.

Are Rivian accessories covered under the vehicle warranty?

Official Rivian accessories carry a separate 1-year / 12,000-mile warranty. Third-party electrical parts may void coverage for related systems.
