Fake charger

 I'm sorry for the late reply. The charger block feels a bit heavy in my hand, however it's hard to compare since I don't have the original in my hands, nor do I have a way to weigh it to know its exact weight. I decided not to unpack the cable so that there are no problems with the return. I put it to charge with another USB-C cable and it shows two lightning icons with the superfast charging protocol and everything looks blue. I only charged 20% of the device so it's very difficult to say what the average charge is with this charger. The charger in the middle of its two connections has a very strange hole and is very poorly finished, I don't know if the original from the Samsung store has the same. I also see at least on the Amazon page that the block should have written on one side: "Low StandBy" which this one doesn't have. Again I have no information on whether the original model should have this written as well.

Thank you, I have mentioned my concern to Amazon customer service and they have allowed me to proceed with a refund. I should have returned it by the end of the week. I guess the only way to be sure of buying the correct charger is to buy it from Amazon or Samsung directly.
