Is this Dell accessory genuine?

Hi, I bought a DELL 65w USB-C Auto Air charger adapter from Amazon: Dell Auto Air Adapter 65W USB-C *Same as 450-AFLE* : Amazon.co.uk: Computers & Accessories

I can't figure out if it is genuine or not. The dell website seems to be useless. I can't seem to search any of the product codes on the Dell website, but I also can't search for the product codes for the charger that is actually on the dell website either.

Why am I suspicious?

Came from amazon, in a A4 size white padded envelope, no dell branding on any packaging. Unsealed plastic bags inside, and I can see very small amounts of glue at the seams of the casing of the charger.

The sticker on the white envelope Reads:

CUS,ADPT,65W,AUTO-AIR,T-C

VPN: 450-AFLE

EAN No: 5397063776092

QTY:1

Inside the envelope was the charger, with a small car socket adapter in a separate bag inside the charger bag, both in an unsealed plastic bag.

One bag has a small label:

CN-0CDH54-DES00-165-0F9Z-A06

Made in China

DP/N 0CDH54

 

The charger body (part which goes into the car socket) reads:

MODEL: ADC-65AB AA Max.power:65W

SN:CN-0CDH54-DES00-165-0F9Z-A06

No CE mark imprinted on this or anything.

Chrome dell logo on the other side

 

The rubber cable tidy attached to the cable has the more typical stuff you would expect such as a CE mark Dell Logo and a few things, one thing that is confusing here is it says the model number is:

Model: DA65NM150 Max.Power:65Watts

and then has the outputs and inputs of the charger

It is genuine? How would I find that out.
