My 2021 R has a 12V outlet just to the left of the SIMRAD display, and 2 USB ports just to the right of the display. It also has USB ports in the armrests just in front of the cockpit and also on the port side in the armrest by the door, as well as by the cupholders in the swingback on the port side.
If yours doesn't have one, you should be able to wire one in pretty easily. I'd look at GreatLakesSkipper to find a proper nautical/waterproof part.
