yeah its a whole unit for charging , .. requires 240V from your electric meter . You dont just plug in an ordinary extension cord .. Chevy is recalling all their BOLT models due to fires starting in batteries while charging .. This crap is just not ready.. Just like wind and solar. We saw in Texas what happens to Turbines and Solar Farms when IT GETS COLD! People died .. We are decades away from getting off fossil fuels. Liberals and govt need to accept that .. and NO! the world is not ending in 10 years as that pea brain AOC says .... But I digress... Managed to get 30 gallons of gas at 4AM today.. no line
