Thanks, yes, the above charger in top post is 50V, 3A, and doesnt have the suggested connector that i proposed.
But actually, i have a sneaking feeling, that even though it would be of use...the connector that i propose, in the top post, does not exist anywhere in the world...would you agree?
As we see, the charger of the top post should really have the proposed connector, but does not.....as we know, it is simply not acceptable for a charger to be killed simply by someone unplugging it when loaded....the general public are not electronics engineers, as we know.... as you know, they have no idea that "Unplugging on load" is a charger killer.
