Do you want to know how to charge your PS4 Controller with a phone charger to not burn it out and damage the battery? You can charge your PS4 controller from the wall outlet, just make sure the charger is 5v and around 1000mA. If the mA is larger, this should be fine. The controller should shut off to prevent over charging, however, this may glitch out sometimes and charge more than needed. Avoid faster chargers that are 9volts.
