Grasside 2‑in‑1 CCS1 & J1772 to NACS Adapter — 250kW DC / 80A AC, Compact Durable Design

A compact 2‑in‑1 Grasside adapter that lets CCS1 and J1772 chargers plug into Tesla/NACS vehicles, supporting up to 250kW DC fast charging and 80A AC charging.

This Grasside adapter converts CCS1 DC and J1772 AC connectors to NACS (Tesla) inlet format so CCS‑enabled Tesla and next‑gen NACS EVs can use many public chargers. It’s engineered for high‑power charging, everyday durability, and safety features that reduce risk during fast charging sessions. Read on for clear answers about compatibility, performance, and practical use on road trips.

Will this adapter work with my Tesla or NACS vehicle?

Compatibility depends on whether your vehicle supports CCS to NACS conversion. It fits Tesla Model 3, Y, X, and S built 2021–2026 that have CCS enabled, and many NACS EVs announced or released with NACS (J3400) compatibility.

• Check: Controls > Software > Additional Vehicle Information > CCS Adapter Support must be enabled.
• Tesla compatibility: Model 3/Y/X/S (2021–2026); not compatible with Cybertruck.
• NACS EV examples: select Chevrolet, Hyundai, Kia, Lexus, Lucid, Rivian, Toyota models (model-year dependent).

How fast will my car charge with this adapter?

The adapter supports up to 250kW DC fast charging (400A) and up to 80A for AC stations, depending on the station and vehicle limits. Real‑world charge speed will reflect your vehicle’s battery state, charger capacity, and network restrictions.

• Max DC: 250kW / 400A (subject to charger and vehicle limits).
• Max AC: 80A for Level 2 J1772 connections that provide that current.
• Typical 20%–80% DC session: roughly 30–40 minutes on compatible chargers, depending on conditions.

What safety and durability features are built into the adapter?

Grasside designed the adapter with active temperature management and robust materials to handle frequent use and varied environments. It includes automatic shutoff thresholds and weather resistance to minimize risk during charging.

• AI temperature control with automatic stop if temps reach high thresholds (stops charging at 185°F).
• Flame‑retardant polycarbonate housing and IP54 dust/water resistance for outdoor use.
• Operating range: -22°F to 122°F for reliable performance across seasons.

Which public charging networks can I access with this adapter?

Using this adapter expands access to CCS1 DC and J1772 AC chargers across major U.S. networks, enabling more routing options and fewer detours. It’s meant to connect with hundreds of thousands of public charging outlets.

• DC fast networks: Electrify America, EVgo, ChargePoint (CCS1 stations), and others supporting CCS1.
• AC networks: J1772 Level 2 chargers at workplaces, malls, and public lots.
• Ideal for road trips where Tesla Superchargers may not be available or convenient.

Who is this for? The Grasside 2in1 CCS & J1772 to NACS adapter is intended for drivers of CCS‑enabled Tesla Model 3, Y, X, and S (2021–2026) and owners of NACS‑standard EVs who want broader access to public CCS and J1772 charging. Choose this if you frequently travel beyond Supercharger routes, need higher DC charging speeds when available, or want a single compact accessory to bridge different charging standards. Confirm CCS adapter support in your vehicle settings before purchasing, and reach out to Grasside support if you have compatibility questions.
