But as some EV drivers know, it\u2019s not always easy to use a Supercharger, especially if you happen to drive an EV like the\u00a0<a href=\"https:\/\/insideevs.com\/reviews\/765053\/2026-rivian-r1s-quad-review\/\" data-inline-widget=\"internal-links\" data-type-id=\"0\" data-params=\"%7B%22article_edition_id%22%3A%22765053%22%2C%22section%22%3A%222%22%2C%22alias%22%3A%222026-rivian-r1s-quad-review%22%7D\">Rivian R1S<\/a> or\u00a0<a href=\"https:\/\/insideevs.com\/news\/754918\/2025-ford-f150-lightning-updates-specs-price\/\" data-inline-widget=\"internal-links\" data-type-id=\"0\" data-params=\"%7B%22article_edition_id%22%3A%22754918%22%2C%22section%22%3A%221%22%2C%22alias%22%3A%222025-ford-f150-lightning-updates-specs-price%22%7D\">Ford F-150 Lightning<\/a>.<\/p>\n<p>Leaving aside the fact that you\u2019ll need an NACS to CCS1 adapter, the Supercharger cable might not reach the charge port many popular EVs, including the Chevy Blazer EV and the aforementioned trucks. The most popular stall version, known as V3, was designed for Tesla EVs, which have the charge port on the rear left, while many American electric pickups and SUVs have their ports on the front left side.<\/p>\n<section contenteditable=\"false\" draggable=\"true\" data-widget=\"video\">\n<div class=\"video-wrapper\"><img decoding=\"async\" class=\"sizer\" draggable=\"false\" src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAJCAYAAAA7KqwyAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAABpJREFUeNpi\/P\/\/PwMlgImBQjBqwLAwACDAAOVfAw9\/ZDvcAAAAAElFTkSuQmCC\" alt=\"\"\/> <\/p>\n<p><iframe allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"\" frameborder=\"0\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/KPyCww4mUZI?si=UMduFrnBLRu7x7R0\" title=\"YouTube video player\" width=\"560\" loading=\"lazy\">[embedded content]<\/iframe><\/p>\n<\/p><\/div>\n<\/section>\n<p>Thankfully, there\u2019s a company out there that is trying to fix two issues with one product. Hannshow\u2019s five-foot extension cable also doubles as a NACS to CCS1 adapter, so it should come in handy for owners of EVs that came with a CCS1 inlet from the factory\u2013like the Gen1 <a href=\"https:\/\/insideevs.com\/rivian\/r1s\/\" data-inline-widget=\"internal-links\">Rivian R1S<\/a> and <a href=\"https:\/\/insideevs.com\/rivian\/r1t\/\" data-inline-widget=\"internal-links\">R1T<\/a>, as well as the <a href=\"https:\/\/insideevs.com\/ford\/f-150-ev\/\" data-inline-widget=\"internal-links\" data-type-id=\"1\" data-params=\"%7B%22make_alias%22%3A%22ford%22%2C%22alias%22%3A%22f-150-ev%22%7D\">Ford F-150 Lightning<\/a>.<\/p>\n<p>That said, the $600 product has some flaws, as InsideEVs contributor and charging expert Tom Moloughney found out during his review of the product. Put simply, he wouldn&#8217;t recommend it as a safe option.<\/p>\n<p>Specs-wise, the extension cable has two thermal sensors inside the connectors, so when the temperature hits 185 degrees Fahrenheit (85 degrees Celsius), the charging session stops automatically.<\/p>\n<p>Furthermore, the charging can be ended by pressing the button on the CCS1 connector, or you can stop the session from the Tesla app. That said, there\u2019s another release button on the NACS connector, which does just that\u2013it only releases the extension cable from the NACS charging cable. It doesn\u2019t stop the charging session, and that\u2019s a big problem because one could inadvertently remove the NACS part first while charging, and that could create a big electrical arc, as power would continue to flow through the charging cable.<\/p>\n<section class=\"relatedContent-new\" contenteditable=\"false\" draggable=\"true\" data-widget=\"related-content\" data-widget-size=\"content\" data-params=\"%7B%22type_id%22%3A0%2C%22title_id%22%3A%22%22%2C%22items%22%3A%5B%7B%22article_edition_id%22%3A%22753558%22%2C%22title%22%3A%22Don%E2%80%99t%20Forget%3A%20Many%20DC%20Fast%20Charging%20Adapters%20Are%20Technically%20Prohibited%22%2C%22alias%22%3A%22dc-fast-charging-adapter-probibited-tesla-evgo-chargepoint-electrify-america%22%2C%22section%22%3A%221%22%2C%22is_video%22%3A%220%22%2C%22images%22%3A%7B%22s5%22%3A%22https%3A%2F%2Fcdn.motor1.com%2Fimages%2Fmgl%2FwlqPEm%2Fs5%2Fhyundai-ioniq-5-adapter.jpg%22%7D%7D%2C%7B%22article_edition_id%22%3A%22748356%22%2C%22title%22%3A%22This%20Tesla%20Supercharger%20Extension%20Cord%20Could%20Be%20A%20Game-Changer%22%2C%22alias%22%3A%22tesla-supercharger-extension-cord-game-changer%22%2C%22section%22%3A%221%22%2C%22is_video%22%3A%220%22%2C%22images%22%3A%7B%22s5%22%3A%22https%3A%2F%2Fcdn.motor1.com%2Fimages%2Fmgl%2Fg4zvj9%2Fs5%2Ftesla-supercharger-extension-cord-a2z.jpg.jpg%22%7D%7D%2C%7B%22article_edition_id%22%3A%22734336%22%2C%22title%22%3A%22Tesla%20Cybertruck%20Engineer%3A%20Don%E2%80%99t%20Even%20Think%20About%20Using%20Supercharger%20Extension%20Cords%22%2C%22alias%22%3A%22tesla-nacs-extension-cable-cybertruck%22%2C%22section%22%3A%221%22%2C%22is_video%22%3A%220%22%2C%22images%22%3A%7B%22s5%22%3A%22https%3A%2F%2Fcdn.motor1.com%2Fimages%2Fmgl%2FxqKp7q%2Fs5%2Ftesla-cybertruck-supercharger-extension-cord-hero.jpg%22%7D%7D%2C%7B%22article_edition_id%22%3A%22734672%22%2C%22title%22%3A%22Tesla%20Supercharger%20Extension%20Cable%20Maker%20Addresses%20Cybertruck%20Engineer's%20Warning%22%2C%22alias%22%3A%22cybertruck-engineer-supercharger-extension-cable%22%2C%22section%22%3A%221%22%2C%22is_video%22%3A%220%22%2C%22images%22%3A%7B%22s5%22%3A%22https%3A%2F%2Fcdn.motor1.com%2Fimages%2Fmgl%2FrKEZkO%2Fs5%2Ftesla-supercharger-extension-cable-a2z-ev-response-hero.jpg%22%7D%7D%5D%7D\">   <\/section>\n<p>For what it\u2019s worth, the company says in the instructions that users should always stop the charging session first by pressing the button on the CCS1 handle or through the station\u2019s app, and then remove the extension cable. But as InsideEVs contributor Tom Moloughney rightly puts it, people don\u2019t read the instructions manual. It would be much safer if the release button on the NACS end of the extension cord also stopped the charging session.<\/p>\n<p>That\u2019s not the only problem with the $600 cable, though. According to Hansshow\u2019s website, the product is rated for a maximum of 250 amps and 1,000 volts, resulting in a maximum power of 250 kilowatts. The problem is that a lot of EVs on the market will ask for a lot more than 250 amps\u2013some require over 500 amps for short stints.<\/p>\n<p>This means that the extension cable will not function as expected in some scenarios. At least that\u2019s what we found out during our testing. When topping up a Ford F-150 Lightning at a Tesla Supercharger, going from 10% to 50% took 30 minutes using the extension cord. When using a certified NACS to CCS1 adapter during an identical charging session, it took 24 minutes.<\/p>\n<section class=\"widget-newsletter\" contenteditable=\"false\" draggable=\"true\" data-widget=\"widget-newsletter\" readability=\"-19.086614173228\">\n<\/section>\n<p>The same extension cable was used to charge a Gen1 Rivian R1S at a different Tesla Supercharger. After plugging in with a dead battery, the car stopped charging after just a couple of minutes, saying the cable was too hot. After unplugging, waiting for 15 minutes and plugging back in, the car accepted a charge for just one minute before ending the session again.<\/p>\n<p>The Ford F-150 Lightning, however, accepted a charge with the same extension cable at the same station. After changing stations, the Rivian R1S charged from 10% to 34% before stopping again. This time, though, there was no error; it just refused to charge, even after unplugging and replugging.<\/p>\n<p>It\u2019s worth noting that with a regular NACS to CCS1 adapter, the same R1S went from 10% to 60% in 26 minutes at the same location.<\/p>\n<p>Hannshow\u2019s NACS to CCS1 extension cable is the only product of its kind that\u2019s currently available for sale. A2Z, another company that makes charging adapters, has a <a href=\"https:\/\/insideevs.com\/news\/748356\/tesla-supercharger-extension-cord-game-changer\/\" data-inline-widget=\"internal-links\" data-type-id=\"0\" data-params=\"%7B%22article_edition_id%22%3A%22748356%22%2C%22section%22%3A%221%22%2C%22alias%22%3A%22tesla-supercharger-extension-cord-game-changer%22%7D\">NACS to NACS extension cable<\/a>, but that\u2019s not on sale yet, with the company saying it expects the first units to ship in the last quarter.<\/p>\n<p>All this being said, there\u2019s another issue that EV owners should be aware of. If anything were to go wrong during a charging session, carmakers might not honor the car\u2019s warranty if anything other than the manufacturer-recommended charging adapter was used.<\/p>\n<p>The product is out there, and it can be used, but there are issues that need to be considered before you plug one in. Make sure to look into safe operation, and consult with safety and charging experts when necessary.<\/p>\n<p>                                                                        <!-- new gallery place, attached gallery --><\/p>\n<div class=\"group isBottomShare mb-spacing-md-lg\">\n<p>\n                                    Share this Story                                <\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>More and more non-Tesla EVs can now charge at Tesla Superchargers, and many of them need charging adapters.
