As an electric vehicle owner with a hardwired charger in my garage, I love the convenience – most of the time. However, the frustration of limited reach is hit me recently. Whether it’s needing to park outside for garage projects or simply wanting to temporarily swap bay positions with my wife’s car, that hardwired cable can feel like a tight leash.
I needed a simple solution: an extension cable that wouldn’t compromise charging speed or introduce safety (HEAT) concerns. The EVDance 21′ J1772 Extension Cable was my pick. I recently tested it out, and it has been a great addition to my EV accessory collection.
Right out of the box, the attention to detail was evident. The cable arrived with a soft, zippered carrying case, a useful addition for keeping things organized when not in use.
This case makes storing the 21-foot cable so much tidier in my garage.
My first impression of the cable itself was its surprising flexibility. Unlike the stiff, unwieldy cable of my stock charger, the EVDance cable coiled up effortlessly.
You can really see how easily this cable bends and coils, making it much easier to handle. I noticed right away it would be less of a hassle to use and store. I even measured the difference in thickness. My stock cable came in at a hefty 20mm.
While the EV Dance cable was a much more manageable 15.6mm
Of course, flexibility is great, but safety and performance are most importnat. I was particularly interested in the build quality of the connectors, and I was pleased to see a prominent weather seal designed to protect against moisture.
The connectors themselves felt robust and clicked securely into both my vehicle’s charging port.
My biggest concern with any extension cable is always the potential for overheating. I conducted a thorough test, charging my EV at its maximum rate of 32 amps for over three hours. The result was reassuring: absolutely no noticeable heat on the cable or the connectors. This confirms that despite being more flexible, the internal wiring is appropriately gauged for the task. In fact, the stock cable was 1F warmer than this extension cable!
The 21-foot length proved to be the perfect balance for my needs, allowing me to comfortably park outside my garage and charge while working inside. And when I was done, the flexibility and the included carrying case made stowing the cable a breeze.
In conclusion, the EVDance 21′ J1772 Extension Cable is a well-designed and high-performing solution for extending the reach of your EV charger. The inclusion of a storage case, the noticeable flexibility for easy handling, the robust connectors with a solid click in place, and most importantly, its ability to deliver maximum charging speeds without excessive heat build-up, make this a fantastic accessory for any EV owner needing a little extra charging freedom.
