Question about Lenovo ThinkPad Hybrid

What is the difference between
Lenovo ThinkPad Hybrid USB C
and
RETEQ Certified 40AF0135EU USB C

With power supply unit

Yes, the dock comes with a 135W power supply if you buy it new as the original item 40AF0135EU.
(With some used or "refurbished" items on the "usual suspect sales platforms" it is often just the "naked" dock without NT and sometimes even without a cable. This is very annoying !)
Galaxus delivers complete manufacturer articles for new goods and thus as said WITH NT !
@ GALAXUS: Unfortunately, it is also not clearly recognisable here in the article details, as only a "charging power" of 90W is specified.
