Hansshow has released the second generation of its NACS to CCS1 extension cable, addressing safety issues from the first version and allowing non-Tesla EV owners to charge more efficiently. The new cable, available in 5- and 8-foot lengths, supports higher power levels and is now open for pre-orders. While it promises convenience at Tesla's vast Supercharger network, its high price and lack of full certification raise questions about its practicality.
Non-Tesla electric vehicle owners have long faced challenges when using Tesla's extensive Supercharger network, which numbers over 25,000 stalls across North America. These chargers were designed with Tesla vehicles in mind, featuring ports on the rear left side and relatively short cables that often force drivers of vehicles from Ford, Rivian, or General Motors to occupy two charging bays simultaneously—a frustration for users and an inefficiency for the network.
Hansshow, an aftermarket accessory maker, aims to resolve this with its second-generation NACS to CCS1 extension cable. The product not only extends the Supercharger's reach but also converts the connection to CCS1, the standard for many non-Tesla EVs. The first-generation cable, launched as a pioneer in this space, suffered from a critical safety flaw: while the CCS1 end had a switch that halted charging upon disconnection, the NACS end lacked this feature, potentially causing dangerous electrical arcing.
The upgraded version eliminates this risk by incorporating active release switches on both ends. It comes in 5-foot and 8-foot options—the latter providing extra flexibility to avoid double-bay usage. Rated for 1,000 volts and 350 amps continuously, it surpasses the original's 250-amp limit and endured testing at 500 amps without overheating. All components carry UL certification, though the full assembly awaits it.
InsideEVs contributor Tom Moloughney, host of State of Charge, tested a pre-production unit and reported seamless performance. It charged his Rivian R1S without issues—unlike the first generation—and matched the speed of a basic adapter on a Ford F-150 Lightning. "It's much better than the first-generation device," Moloughney noted, praising the dual switches, added length, and enhanced amperage capacity.
Pre-orders are live, with deliveries set for mid-January. The 5-foot model costs $629, and the 8-foot version $729. However, the price is steep for occasional use, and major automakers like Tesla advise against unapproved adapters, warning they could void vehicle warranties. This innovation highlights the ongoing adaptation of charging infrastructure but underscores the need for standardized, certified solutions.
