As such, UL and the major NRTLs will never approve "everything sockets". This could not handle 0.5 amps - certainly 16A is out of the question. I suspect you were dealing with one of the infamous Chinese "everything sockets", which make contact with every kind of plug, but very poor contact with any of them. We specialize in iPhones, iPads, Samsung, LG, HTC, MacBooks, and much more. That is not the normal contact point for a UL-listed or CSA-listed NEMA 5-15 socket, which is on the 2 faces of each pin. Atlanta and Buckheads 1 repair store for cell Phone, tablet, and laptop repair. The pin location of this arcing is highly unusual. Such standards do not always exist in the third world, or are not enforced. Both in terms of contact design and quality, and also the plastics used must resist and not accelerate fire, and not emit toxic smoke if charred by external fire. This sort of thing is why UL and the other national testing labs (CSA, TUV, BSI etc.) have very high standards for manufacture of sockets and plugs. When connecting the USB-C cable to the computer, you may notice that the USB-C cable is loose or does not snap into place anymore. If the contacts don't grip the plug securely, it is defective and don't use it. The lesson to learn here is don't use AC power sockets that are loose. When I had a Macbook PS that had a cord instead of a pin-frob, I left the cord behind and just grabbed a local C7 cord. Each of these chargers has two USB-C outputs to charge a pair of. It can mate with any common "IEC C7" appliance cord. Most attention fell on the M2 MacBook Pro and the redesigned MacBook Air, but it also released a pair of new USB-C chargers.

Or, look at the socket on the power block - that is IEC C8. If theres visible gunk stuck in the USB port, then make sure your Mac is completely switched off and disconnected from the power supply, and then take a non. The rest of the charger is fine, you can get "just the little clip-on plug device" by buying any genuine Apple iPad charger, which use the same clip-on. I would not attempt to dress the pins with a file, as they are plated, and you are exposing the underlying brass, which would then oxidize, worsening contact further. It won't hurt your Mac, but it might start a fire which would definitely damage your Mac. The part with the pins is scrap, since the arc damage will cause its contact with other plugs to be unreliable, which in turn could cause even more arcing.
Arcing like this makes an impressive amount of heat - which dips the voltage to the appliance, which on a switching power supply increases current further, lather rinse repeat. This worsened the contact and worsened the arcing.
This arcing acted exactly like arc welding ( was arc welding) and gouged and pitted the metal, and made smoke/soot (probably from the poor grade of plastic of the Chinese socket). AC mains voltage electricity was able to leap across the very small gap between pin and socket.

This is due to series arcing: power was flowing through the adapter normally, but making poor contact. TLDR: Wrecked by series arcing, from inserting in loose socket.
