A GM spokesperson told TechCrunch its adapters have been specifically designed to protect GM EV batteries while charging and that its vehicle warranty doesn’t cover damage to vehicle parts resulting from the use of non-GM approved adapters.
In late August, Tesla posted on X that it had ramped up production of adapters. That statement, combined with GM’s announcement, could mean that even more non-Tesla EVs will be pulling up to Supercharger stations soon. They’ll all have to download the Tesla app so they can pay for charging.
