This product is very helpful in many ways, first of all I love the fast charging. This product DOES have fact charging if your device has QUALCOMM fast charging 2.0, If your device doesn't then the fast charging wouldn't work. Please know that before buying this product, I know that my device does have that and I did get fast charging. However on the speeds on the fast charging are a bit different then what you would expect. The fast charging would be called fast charging but the wattage would peak at about 11.4w max, Minimum was 8.0 while using the screen. Also these chargers get hot and kind of loud under use, meaning they aren't original. For the price I mean its not bad but its just something to keep in mind. One thing I would love is that if the product would have the samsung logo on the side that it would, like I said earlier this isn't a samsung product so maybe that's something that cant be copied due to copyright reasons. Most of the stuff on the back are normal from the real charger. Also when you are wanting to use this product to devices that need more then 15w to charge (Such as a tablet) it may not be enough. This was enough since I have a samsung s6 for school. Another thing I should note that if your cable cant do data then your cable isn't fast charging compatible and that can be an issue that your fast charging cant work. Overall I love this product and everything that it has. Highly recommend as a fast charger.
