Also make sure the insulator area is clean! As junk can prevent good mating as well.

Now the fun part I have two chargers on my desk both look exactly! the same!! Which is the real one and which is the knockoff ??? You just can’t tell. The only way is to weigh them the lighter one is the knockoff but that assumes you have one of each and are the same series.
One of the companies I had worked at had a very expensive encounter with a knockoff charger! It cost them well over 3 million! One of their engineers forgot his charger at home as he had an important meeting the next day he found his way to a local computer shop to pickup a charger no big deal, was he so wrong! He went back to the hotel he was staying, plugged his system in and went to dinner. When he got back to the hotel the building was evacuated as smoke was billowing out the windows. Sadly the investigator identified the fire started in his room! The charger started the fire. After a few years of litigation it was a very expensive charger! The store which sold the charger also was sued as well and they folded up from cost of their litigation.
