@likejudo Stepping back a bit, you initially mentioned that your phone was charging slowly with the front 12V outlet. What was the measured voltage of the outlet? Did to plug in other accessories to the outlet to assess the functionality? How long was the phone plugged into the outlet? Was the vehicle running during the entire duration of charging? How many different phone chargers have you tried? What phone do you have? What phone charger are you using?
It looks like there are two 12v outlets in your vehicle, do neither of them not charge your phone fast enough?
If the outlet is indeed bad then you can proceed to remove it.
With all of the progress you've made, it looks like you may be able to use a pry tool to remove the outlet from the front panel. Put the blades of the tool between the black ring and the panel, rock
GENTLY, then rotate the blades 90 degrees rock again, repeat. You should hear a pop when a pressure clip releases. Repeat until it loosens up, you then should be able to pull it free.
