Not exactly but free energy none the less. Nice surprise when we pulled into the marina this year. They installed several of these in the town where our Marina is located. This one is in the marina parking lot so really convenient for us. Third time I have used the chargers. Being a very small town, there are hardly any EVs here and the stalls are always empty which I am sure will change as time goes on. The trip out to the marina is a good 2 hour drive at highway speed and that would be at 120kph+ all the way. Needless to say a top off of electrons is nice before we return home especially when it is free. Will help offset the cost of boat gas
