Shopping for mobile device' accessories can be a tiring process as you never know what to expect, but I have learned something so far as a techy person. By the way, it is common knowledge. Popular brands have the most fake and counterfeit products as cheap Chinese manufacturers try to piggyback on their successes and produce cheap ripoffs. This is why it is very difficult to get a Samsung or iPhone charger that is not counterfeited from anywhere other than their respective official stores.
For me, I have come to a simple conclusion of going for accessory brands rather than phone brands. For example, instead of getting a type C charger and cable branded Samsung from an online store, e.g., Jumia, I will go for an Anker, Oraimo, New Age, or even a Chupez type C charger. In my experience they have proved to be more reliable while being more affordable (though Anker products are quite pricey).
These accessory brands are not immune to counterfeiting, and the best way to get the originals, from what I have learned, is by going in person. Most accessory shops would stock both the fakes and the originals and sell both in one location. Most often, they will present you with the fake when you come in (fakes have higher profit margins), but if you can insist that you need the original they would usually go back and bring the original (you have to act as if you know its fake in the first place). If what they have presented is the original, they are likely to present you with the fake so that you can make comparisons.
For my favourite accessory brand so far, Oraimo, which now has a lot of deepfakes everywhere, they have a new approach, in which they demand that only their original products are on display in their specially provided showcase (which is usually a tall, black and green, counter-like construction with 2 Face on it), and they usually send inspectors to ensure that retailers are compliant.
Ah! It is already very long, oh! I take a break!
