1) Does NOT arrive in OEM packaging. The charger and the cable were both separately packaged in their own plastic bags and then both stuffed in a plastic mailer, with no other packaging.
2) The USB-C cable does NOT appear to be an OEM Samsung cable. Every OEM cable I have ever gotten from Samsung had a part%23/ID label on one end, this did not. It is extremely stiff, so stiff that when removed from it's paper holder it opened up like a spring.
3) Charges ok to 12W max output consistently - BUT... Higher output drops completely after a few seconds. This is definitely not capable of the designed and advertised 45 Watt output. So it does not work as advertised.
4) Maybe its just defective. It looks real enough, but like others have stated maybe it's fake. I definitely have my doubts as to the authenticity, and I should have paid more attention to the other negative reviews.
5) Thankfully, this item was eligible for "In-Store Return/Refund" and the customer service rep actually knew how to do it properly with zero hassle.
