My thoughts on the charging unit:
My thoughts on the 220 Volt SPX charging unit: I'm not a fan of the "kinky curled chord" as it adds extra and excessive weight and pull on the car connector nozzle. This is rather obvious as the anti-stress collar has failed in a comparatively short time. I would have much preferred just a straight cord that could be adjusted or ordered to the actual length needed for the particular installation situation. Also the actual electronics inside the round case are far smaller than the plastic case itself. If one needs to curl the cord, all one would need is a plastic garden hose holder that usually sell for under $10.00 at most hardware stores.
So in short, I would like to have seen a smaller 220/240 charging unit that was portable. Ideally a single unit that could easily be switched from 110/120 volts or 220/240 volts depending on the input voltage to the charger at any particular location.
As it stands now, the SPX saucer charger is an over sized and overly clumsy device (considering the weight of the connecting cord) which could be greatly improved by using standard construction style straight cords. As the unit only requires a 20 amp breaker, it seems to me that a #12 or possibly #10 gauge cord would do the job. I don't know the gauge of the wire inside kinky curly cord. but there is noticeable, but not excessive heat within that chord when the car is being charged.
What I do know for sure is that the kinky curly cord is not at all useful, and does add unnecessary weight and strain on the connectors which ultimately will result in a failure of the cord at the point of entry to the connectors. There have been two instances when the car failed to charge. The exact cause / reason is unknown, but what I did notice the other day is that if the connector from the charger is wiggled just a little bit, the car looses communication with the charger and fails to charge. The only way to restore it is to completely disconnect the cord connecting device from the vehicle, and re-plug it in. All in all the charging system is not as sturdy or robust as it should be, and where it needs to be.
