...as Lew notes, these "speedier" outlets leave much to be desired. I have replaced three of them on my new trailer, but for different reasons: a) the outdoor outlet has a plastic cover -- I prefer stainless steel, so when I replaced the cover, I replaced the outlet, b) I find it a major convenience to have USB outlets where I spend time -- so I replaced the two 120V outlets adjacent to either side of my sofa/recliner with 120V/USB outlets. I suppose the "speed wire" work OK, but it makes me uncomfortable....particularly when they also serve as a junction box for other circuits.
