Type 1 ev charger extension cable
The professional solution for reaching distant charging points. Our Type 1 EV charger extension cable provides the extra length needed to connect any SAE J1772 vehicle to your existing charging station. Available in ratings up to 50A (12kW), this is not a standard extension cord—it is a purpose-built EVSE component featuring 99.9% pure copper conductors and silver-plated terminals to ensure zero-loss power transmission and maximum thermal safety.

Bridging the Gap in EV Infrastructure
Whether your driveway is too long or a public station is blocked, our Type 1 extension cable offers a secure and efficient bridge. While many manufacturers advise against generic extension cords, our cables are engineered specifically for the sustained, high-current loads of Level 2 charging. We use oversized internal conductors to mitigate voltage drop, ensuring your vehicle receives the full charging speed without the risk of overheating.
Engineering & Safety Integrity
In the world of high-power EV accessories, material quality is the difference between reliability and failure. We prioritize safety through industrial-grade specifications:
-
Superior Silver-Plated Terminals: Each connector features silver-plated copper alloy contacts. Silver provides the lowest contact resistance ($\leq 0.5\text{m}\Omega$), which is critical for preventing terminal heat rise during 8+ hour charging cycles at 40A or 50A.
-
Advanced TPU Cable Jacket: Unlike cheaper PVC alternatives, our cables are jacketed in Thermoplastic Polyurethane (TPU). This material remains flexible and easy to coil even at -30°C, resists UV degradation in outdoor settings, and is highly resistant to automotive oils and abrasion.
-
Intelligent Handshake Pass-Through: The cable fully supports the Control Pilot (CP) and Proximity Pilot (PP) signal pins. This ensures the vehicle and charger can communicate the maximum allowable current and verify grounding before power flows, maintaining all native safety features of your EVSE.
-
Ruggedized Weatherproofing: Rated at IP66 (coupled), our connectors are designed to withstand heavy rain and dust. The high-strength thermoplastic shell is tested to survive a 2-ton vehicle drive-over, ensuring longevity in busy residential or commercial environments.

🛠️ Selection Guide: Matching Amperage to Your Vehicle
To ensure Trustworthiness and efficiency, select a cable that matches or exceeds your charger’s output:
-
16A: Best for Level 1 charging and older Plug-in Hybrids (PHEVs).
-
32A / 40A: The standard for most modern Level 2 home charging stations (7kW–9kW).
-
50A: The “High-Performance” choice for high-capacity EVs (e.g., Ford F-150 Lightning, Hummer EV). Selecting a 50A cable for a 32A charger provides a “thermal buffer,” allowing the cable to run cooler and last longer.
Frequently Asked Questions (FAQ)
Q: Will this slow down my charging speed?
A: No. Because we use high-purity copper and oversized gauges, the voltage drop is negligible ($< 1\%$). Your vehicle will charge at the same rate as if it were plugged directly into the station.
Q: Can I leave this outside in the snow/rain?
A: Yes. The cable is rated IP66 when connected. However, we always recommend keeping the connection points off the ground in standing water to maintain maximum safety.
Q: Is TPU really better than PVC?
A: Absolutely. PVC cables become stiff and hard to manage in cold weather. Our TPU cables remain flexible down to $-30^\circ\text{C}$ and have a much higher resistance to mechanical wear and UV sun damage.
