I haven't attached the fuse block to the inside of the cabinet yet. (when the picture was taken I was still installing everything.)
I really like that the dual USB port has a built in voltmeter so I can instantly see what the battery power level is. It also came with an on/off switch so it's not constantly powered. I just haven't drilled the hole for that yet.
I'm preparing the trailer so my wife can use her CPAP machine easily and be able to charge our phones without having to lug around ciggy adapters.
I was able to test it out last weekend and everything worked well.
I did that exact same thing a few years ago and also added 2 120V duplex outlets for convenience. I never post photos as not a picture person plus complex process to do so IMO as not a teckkie person.
