If you have been following and building EVs for the past 10 years you will know one thing for sure, there is always a new battery tech that is "almost" ready and there are many companies that come out of nowhere or existing companies that think they will make a quick fortune selling things like this and they have no clue what the EV market is really like or even how to market their products. Some do this better than others but still miss the big picture and are chasing their tails for the big "green" bucks or think they are going to save the world. The problem is they are usually scammers or poor to very poor business people. A perfect example is Myers Motors or perhaps Zap who is great at 10 years of endless press releases and selling cheap piles of Chinese junk.
The EVSE market will be like that of the extension cord if many EVs are sold. Those grabbing the Govt money will spend it and make a few bucks if they are smart and then fade away. Starting a company just to make and sell EVSE products is like entering in the high-end extension cord market. Good luck.
