There are two options to charge a PS4 controller, one is by using USB ports on your console, by using wall charger and also by a wireless charging dock. But, there is a little bit of difference in the charging time.
So you can choose anyone method which is more convenient to you. The console outputs a maximum of 5V900ma. Along with this, the dual shock four controllers have a power of rating 5V. Yes, this is the power that needs to operate controller while charging.
The controller will ask for 800ma when it is plugged into the PS4 console or a wall charger. But, you should check whether the charger output has at least 800ma. This is crucial while using a wall charger, as it will put your charger in stress and maybe burn it. Along with this, it will not charge sufficiently.
So it doesn't matter which charger you choose, whether a wall charger or a console port. Their charging output is similar and they draw 800ma power. Therefore, both are the same, and you can choose any of the methods for charging, but wireless charging is the best way to charge your ps4 controller.
Try to avoid using quick USB chargers – If the charger shows two output, then don't use them since fast charges offer two power outputs, one is 5V, and the other is 9V output.
It is preferred to use a compatible charger to draw 9V power. Many users report that a quick charger may damage PS4 controllers. So, it is better to be on the safer side.
So, it is not acceptable to take the risk of using a quick charger with the PS4 Controller. But, if you have more money to burn it, then it is your choice. It is recommended to try to protect your expensive controller from damaging.
