There are 3 different ways:
1. Man buying of "Amazon.com" Only then it really is also Amazon, here the price is often higher but it is 100% Authenticity
2. You buy it from another dealer but with shipping via Amazon, then there is the following
"Sales by XYZ and shipped by Amazon.com"
Then there is indeed sent from Amazon but you have not purchased from Amazon but with the actual products.
Of course, it should be original commodity but surely you can because not necessarily here ...
3. You buy it completely distributors ABC then makes Amazon only the settlement and the merchant ships themselves. The original one here gets goods is obviously not a matter of course.
I have the charger cable at the seller "Amazon.com" bought so possibility no. 1
It was in a nice Samsung packaging delivered and sealed with these sealing Samsung "Do nof accept if seal is broken." Exactly the same seal which is also on the board from the Tablet or Smartphone. Then the cable: It is 100% identical to the cable which the tablet was ... at virtually identical to the last detail !!! The cable itself, the label on the cable, the cable length, the plug, the label on the connectors and also the fit. It is 100% original !!
Works in the car as it should.
