Not all Superchargers are open to NACS partners (requires adapter for CCS1 vehicles; you should check if Toyota is now included or when it will be included) or other EVs (Magic Dock). Also, even some of the Superchargers open to NACS partners have short cables designed for Tesla left-rear charging ports, so that it may require creative parking to plug into a vehicle with another charging port location.

If you click on a specific Supercharger, you will see that the prices are higher for non-Tesla vehicles (presumably, they want to make money on other EVs, versus offering lower prices for Tesla vehicles to get people to buy Tesla vehicles).
