Power supply seems fine. According to my voltmeters it reads 12.22 to 12.24 volts with no load. I think it will drop a bit under load. So I think that's fine. The metal connector on the attached 5.5mm barrel connector is approximately 10mm long. That's what I expected. It fits all the devices I would use it with. I think a 10mm length is the industry standard for 5.5mm barrel connectors. Wikipedia states that 9.5 mm. who can measure it. Near enough. But I am very disappointed that all 9 adapters in the kit have 12mm long plugs. They don't fit flush with my devices. There is a gap because of that extra 2mm. That was a major reason why I ordered this product. For adapter plugs. They are usable. But their length is oddly too great. Too bad. Besides, it's just a joke. All these plugs have a letter on them. But two different sizes are marked with G. And the other two are marked with H.
