Unfortunately, with my Galaxy S4, the power of my charger was no longer sufficient.
GPS use, despite the charge, the phone was emptying. Slower than if I had not plugged in, but if my phone was empty, it was impossible to use it as GPS, and long journey, it became problematic.
I bought other models to solve this problem without success.
With this charger, for cons, the phone load despite a GPS use.
The charger heats a little bit (it's warm) without further alarming extent.
I am fully satisfied.
