I bought this Southking SK-EV16 last summer, and have only used it twice. Its condition is almost "like new", but its connector has rough scraped edges since I dropped it on driveway. I am asking for $100 total, shipped, to contiguous US. (Extra to AK/HI.)
I chose it for its adjustable pilot current feature, enabling use on existing 15A circuits, and being ready for future improved wiring. What I did not know when I bought it is, it defaults to 16A setting. To change current setting requires some patience: depressing a button lasting a few seconds followed by a few quick presses. Also, it is not as weather resistant as I had hoped. Unlike bundled "granny charge cords", which are very water resistant, the Southking SK-EV16 lacks an O-ring or gasket sealing its control box. I bought SK-EV16 intending to leave it on ground, but I am not confident it will survive. The originally equipped Nissan/Panasonic brick is doing fine there, exposed to puddle, splash, and snow.
What else to know about SK-EV16: it does not feature RCD/CCID nor GCM/GMI. This means it does not require a grounding/grounded outlet: it can be used with any old mains receptacle, even ungrounded "two prong outlets", with a ground-cheater plug adapter. (One can always use a cord-inline GFCI, if RCD protection is desired).
Compare to ASIN B08D8XWJ1H (has a black connector), but with white J1772-2009 connector.
