NACS to NACS Extension Cord | DC | 400A | Compatible with Superchargers

Latest Update: DC Extension Cord Certification (2026-21-01)
The DC extension cord is currently undergoing UL certification. In tandem with this process, two OEMs and one CPO are rigorously testing the unit to ensure its safety and performance align with industry standards.

We recognize the high demand for this product, but we want to be clear: this is a safety-critical component. We will not release it until it is fully certified and formally accepted by our industry stakeholders.

Why Safety Comes First While other options exist on the market where only the cable itself is certified, we strongly advise against using unverified DC extension cords. A product of this nature requires:
- Precision Engineering: To handle high-voltage loads without degradation.
- Integrated Safety Mechanisms: To protect both the user and the vehicle.
- Thorough Market Research: To ensure compatibility across various charging infrastructures.

We are intentionally taking our time to get this right. For us, safety is the only priority—we value the integrity of our product and the security of our users far above the potential revenue from a premature release.

Latest news as of the 5th of November, 2025 :
Product is finalized with dozens of improvements for durability, reliability and safety. A2Z's full organo-silicon insulation is used on both ends of the connectors. The extension cord is under certification. Finally, the extension cord is in the hands of 2 OEMs and one CPO in the U.S. for evaluation prior to release.

Latest news as of the 23rd of July, 2025 :
The DC extension cord's tooling has been finished, the DC extension cord has been submitted to CSA for a UL certification. The ETA for the certification to be completed is by Q4 of 2025. The extension cord will be rated for 400A with non-liquid cooled cables.

This DC NACS extension cord will allow EV owners to easily have access to NACS DC chargers without struggling for parking or reaching the NACS connector.

Ensuring Safety with A2Z EV NACS DC Extension Cord

Our NACS DC extension cord is engineered to prioritize safety, providing users with reliable and secure charging experiences. Let's delve into the key safety features that define our extension cord:

1. Temperature Monitoring and Power Management:

 

NACS DC chargers and electric vehicles (EVs) employ a precise temperature monitoring system to ensure safety during charging. This system continually monitors the temperature of the DC pins, responding promptly to any temperature increases. When elevated temperatures are detected, both the power provided by the NACS DC chargers and the power requested by the vehicle are reduced accordingly. This dynamic power adjustment effectively mitigates the risk of overheating and minimizes the potential for fire hazards.

This intelligent and proactive approach to temperature management ensures the safety and reliability of the charging process, offering peace of mind to users. It is essential to understand that this safety protocol is integrated into NACS DC chargers and vehicles.

2. Active Locking Mechanism for Secure Connection:
Safety extends beyond electrical parameters. To prevent accidents and ensure a stable charging connection, our extension cords feature an active locking mechanism. This mechanism effectively prevents accidental disconnections while the cord is in use under load, guaranteeing a secure and uninterrupted charging session.

3. Temperature Sensor Switches - An Additional Safety Layer:
Within the extension cord connector, we have implemented temperature sensor switches, commonly known as "kill switches." These switches serve as an extra layer of protection. In the event of unexpected temperature spikes, these switches trigger an immediate disconnection of power. This redundancy adds an extra level of security, reinforcing the safety of the charging process.

4. Clarifying Misinformation and Ensuring Accuracy:
In the face of misinformation circulating about extension cords, it is vital to emphasize that our NACS DC extension cord meets rigorous safety standards and are fully compatible with NACS DC chargers and EV charge ports. By providing precise and verified information regarding the safety features and functionality of our extension cords, we aim to dispel any misconceptions and bolster user confidence in the reliability and safety of our products.

In summary, the A2Z EV NACS DC extension cord offers a balanced blend of safety and compatibility. The incorporation of temperature monitoring, active locking mechanisms, and temperature sensor switches assures users of a secure charging experience. Our unwavering commitment to transparency and accuracy underscores our dedication to ensuring the safety and trust of our users when utilizing our extension cords for their electric vehicle charging needs.
