While I love the clean look of the flush mount integrated solutions, I feel that the specs and standards change too often for my liking (I'm looking at you 5v, 1 amp outlet+usb combo in my kitchen). When wiring up my truck bed I went with the boring 12v cig plugs for everything (on dedicated fused lines so I can pull 15amp on each one concurrently if I wanted). The ARB fridge plugs in without issue, and for charging I've been happy with the Anker brand products. Using their USBC-PD plug (https://www.anker.com/products/variant/powerdrive-speed--duo/A22270F1) should charge your macbook and phone without issue (rated for 30 watts and only $24 on amazon) . And a couple years down the road if you need a different power level, cable, interface, etc, someone will enviably make a "car charger" for it that you can simply plugin to upgrade. (my $0.02)
