Most electric vehicle supply equipment (commonly called EVSE or *incorrectly* electric vehicle chargers) come with a NEMA 10-30 plug.
Adapters exist to allow you to plug into dryer outlets, or RV and campground outlets.
When looking for an adapter, make sure it is rated to handle the maximum current your EVSE may require.
Parkworld makes an adapter that takes a Nema 10-30 plug that has a 14-50 receptable for Tesla EVSE to plug into. It’s available from Amazon for around $40 source
