Imagine never having to worry about your non-Tesla EV hogging two Supercharger bays again. That’s the promise of a groundbreaking new accessory that’s turning heads in the EV community. But here’s where it gets controversial: while it claims to solve a major pain point, it comes with a hefty price tag and a few caveats that might make you think twice. Let’s dive in.
A game-changing extension cable and charging adapter hybrid is now available for pre-order, and it’s designed to tackle the frustrations non-Tesla EV owners face when using Tesla Superchargers. The second-generation Hansshow NACS to CCS1 extension cable isn’t just an upgrade—it’s a complete overhaul of its predecessor, addressing every flaw and adding features that make it a must-have for Rivian, Ford, and GM EV owners. The standout? An 8-foot version that ensures you can charge your vehicle without monopolizing two charging bays, a common headache for non-Tesla drivers.
There’s no denying the appeal of accessing Tesla’s vast network of over 25,000 Superchargers, the largest and most reliable DC fast-charging system in North America. For non-Tesla EV owners, this can be a game-changer, but it hasn’t been without its hiccups. While Superchargers are ubiquitous, they were designed with Tesla’s rear-left charging port in mind. This leaves owners of other EVs, like those from Ford, Rivian, and General Motors, grappling with short cables that often force them to occupy two charging stalls—a far-from-ideal situation.
And this is the part most people miss: the growing necessity of charging adapters in an EV owner’s life. Enter Hansshow’s innovative solution, a product that claims to kill two birds with one stone. Their NACS to CCS1 extension cable not only extends the Supercharger’s reach but also includes a CCS1 connector, streamlining the charging process for non-Tesla vehicles.
The second-generation model has been put to the test by InsideEVs contributor and State of Charge host Tom Moloughney, who got his hands on a pre-production unit. The first-generation cable, while pioneering, had a critical design flaw: a safety switch on the CCS1 side that halted charging when pressed, but a physical switch on the NACS side that didn’t stop electricity flow, risking a dangerous electric arc. This flaw was so severe that Tom warned against purchasing it.
But Hansshow didn’t just fix the issue—they went above and beyond. The new cable is available in 5- and 8-foot lengths (up from the original 5-foot only), and it’s rated for 1,000 volts and 350 amps continuously, with successful testing at 500 amps without overheating. The company also emphasizes that all components are UL-certified, though the product as a whole is still pending full certification. Is this enough to win over skeptical EV owners?
In real-world testing, Tom found the second-generation cable to perform flawlessly. Unlike the first version, which struggled with his Rivian R1S and extended charging times for his Ford F-150 Lightning, this new model showed no noticeable difference compared to a standard NACS to CCS1 adapter. With improved safety features, longer reach, and higher amperage ratings, it’s a significant step up. Pre-orders are open now, with deliveries starting mid-January, priced at $629 for the 5-foot version and $729 for the 8-foot version.
But here’s the catch: while it solves the dual-bay dilemma, the price is steep, and the tested unit isn’t the final production model. Plus, Tesla and other automakers explicitly warn against using unapproved charging adapters, which could void your vehicle’s warranty if something goes wrong. Is the convenience worth the risk?
