If you want to take advantage of your wireless charger on your desk this is a great option. Unlike the one that Samsung makes, this unit has 3 extra usb charger with it as well. One of them is the Quick Charge 3.0 by Qualcomm. Like my Galaxy S7 edge, which has quick charge build in, it can charge my phone from near 0% to 50% in 30 minutes!
It runs $38.00 on Amazon.com which is the same price if not cheaper than the ones Samsung makes.
