While I actually like the form factor of this device it simply will not charge an iPhone at 7.5 watts as advertised. I was using a QC 3.0 charger, took my case off, and killed any nonessential processes and it still only charged at 5 watts. This device cost entirely too much for a 5 watt charger.
Output:
negative
