NEMA 10-30P to 14-50R EV Charger Adapter Extension Cord

WARNING: If you need an adaptor for charging your EV at a powered campsite or RV site, typical adaptors WILL NOT WORK! Ensure you buy an adaptor that is specifically designed for EV charging.
Conversely, never use an EV-specific adaptor for charging or powering from the Pro Power Onboard, an RV, or generator. Each type is specific for its use.

I like this particular adaptor cord because of the robust build and the length, especially useful at an RV site.
