if i connect a apple 40w dynamic to macbook the mcbook should show the charger serial number ? if it doesnt show it means it is fake?

Original Title: 40w dynamic
Sorry, but I don't use this charging block for my MacBook Pro, so I can't test that.
But Apple does not mention in this article, that an Apple Power Adapter will show the serial number on the connected device.
Find the serial number of your Apple product - Apple Support
Did you buy it directly from Apple or an Authorised Apple Reseller?
40W Dynamic Power Adapter with 60W Max - Apple
from a reseller . Actually i heard from a friend that the apple store ones dont show too . What do you think ?
I have the same question.
I bought the UK version from Apple and on my MacBook Pro M4 with MacOS 26.2 shows full information including serial number.
With the A3351 (US two prong version), mine shows just generic information.
It also has holes in the prongs which all of the images from the US of people unboxing, the genuine version doesn’t appear to have the holes.
The PowerZ charge tester does show it as full USB 3.2 with all expected voltages etc., so very strange.
I have queried the eBay seller and am waiting for a reply.

At minimum you should have a known genuine OEM power adapter to compare. However, even then you may not be certain since some scammers may make it nearly impossible to tell the difference. I cannot find any Apple article for identifying an OEM power adapter versus a counterfeit one.
The only way to feel safe is buying from a trustworthy & reputable vendor.
How do I verify the authenticity of an Apple 40W Dynamic charger with my MacBook?
