Apple 5W USB Power Adapter 2-Pack

Everything, from the marketing on Amazon to the pulltab of the box, indicated this to be a genuine Apple product. However, upon comparing to other known genuine chargers, I'm not too sure. -My oldest charger is likely from 2014 when I bought my first iPhone. It has the green dot and no Apple logo. (The green dot began following a 2008 recall to indicate an updated design and later replaced by the Apple logo towards the top.) Silkscreen is strong and sharp says "Flextronics" between the prongs. -The chargers I purchased from an official Apple Store today (5/2021, box copyright 2019) at the mall for $19 apiece are nearly identical to the one from 2014 except no green dot and has the Apple logo towards the top. -The chargers I purchased on Amazon in 2020 for $12 apiece are identical at first glance as well as 2nd glance, BUT the silkscreen is softer and almost illegible and "Flextronics" has been replaced by a mystery word. (Apparently, one authentic manufacturer is "Artesyn".)
