I had a similar experience the first time I used a supercharger. It is such an elegant solution to the problem of how to take long road trips in an electric vehicle.
There are still some limitations such as how the power tapers off as the battery fills up and superchargers that are located in places where there is not much to do other than sit in the car and wait for it to finish. But I am still amazed by how well it all works. And that a relatively young company could succeed at something so ambitious.
