NACS to CCS EV Adapter - Access Tesla Superchargers Nationwide

In this review the Lectron NACS to CCS adapter is evaluated for owners of CCS1 electric vehicles who need fast access to Tesla Superchargers. The bottom line: this adapter is for drivers whose automaker provides Supercharger access and who want a robust, UL 2252 certified solution to tap into V3 and V4 networks. It stands out because of its UL 2252 certification and secure interlock design, which together prioritize safety during high-current DC fast charging.

Key Features

• Access to Tesla Superchargers: Unlocks connection to 23,500+ V3 and V4 Tesla Superchargers so compatible CCS1 EVs can charge on a widely available fast network.
• UL 2252 certified: The adapter is the first publicly available NACS to CCS adapter certified under UL 2252 by SGS, offering verified electrical, thermal and mechanical safety performance.
• Secure interlock design: A built-in interlock helps ensure the plug is fully seated and locked before high-voltage DC charging begins, reducing the risk of incomplete connections.
• High current rating: Rated for 500A and 1000V, the adapter supports lightning-fast charging that can deliver up to about 150 miles in 15 minutes depending on vehicle and charger generation.
• Durable construction: Built for repeated high-speed charging sessions with materials and mechanical design intended for long-term use.

Who It's For

The adapter is best for owners of CCS1-equipped electric cars whose automaker permits access to Tesla Superchargers and who want the fastest public DC charging available. It is most useful for longer trips or frequent fast-charge use where minimizing dwell time at stations matters.

This is not for Tesla vehicles or for drivers who rely on AC level 2 charging ports, and it will not enable access if the automaker has not granted Supercharger access to that CCS1 model. Buyers should also be prepared for a heavier adapter than some expect, as several customers commented on its weight.

Pros & Cons

Pros

• Certified under UL 2252 for verified safety and thermal performance.
• Enables access to thousands of V3 and V4 Tesla Superchargers for compatible CCS1 EVs.
• High 500A/1000V rating provides very fast DC charging capability when supported by vehicle and charger.
• Secure interlock helps ensure a reliable, fully seated connection during charging.

Cons

• Heavier than some users expect, which may affect handling when plugging and unplugging.
• Only works with supported CCS1 EVs that have Supercharger access from their automaker; not universal.

Our Verdict

For CCS1 EV owners approved for Supercharger access, this adapter is a strong, safety-focused option that delivers high charging rates and broad Tesla network access. The UL 2252 certification and interlock design make it a sensible buy for drivers who prioritize reliable high-power charging, though a bit of extra weight and the need for automaker permission are practical limitations to consider.

Frequently Asked Questions

Will this adapter work with any Tesla charger?
It is designed specifically for Tesla V3 and V4 Superchargers and enables connection to those networks, but only for CCS1 EVs that have Supercharger access from their automaker.

Is it safe for high-power charging?
Yes, it is UL 2252 certified and includes a built-in interlock to ensure a secure connection before high-voltage DC charging begins.

Can a Tesla vehicle use this adapter?
No, the adapter is not compatible with Tesla vehicles and is intended only for non-Tesla CCS1 cars seeking Supercharger access.
