Look like USB chargers to me.
I installed a bunch of USB charging ports that are integrated in 120 volt outlets along with several 12volt USB ports. They work great and it is nice to have a charging port wherever you happen to sit on the boat.
Greetings,
IF you've already got a 120V duplex, these are plug and play. No wiring necessary.

What exactly does that auto pilot knob do?
Pilots the boat automatically...
Installed two double USB plugs - one at lower helm and one on flybridge. For phones, and for IPad Pro for navigation [emoji106]View attachment 89927View attachment 89928
