Review on CUZEC Adapter Socket Terminal CU10191B by Juan Crane

I was hoping to be able to just plug this cable into my RV's deep cycle battery and use the cigarette lighter socket to power a portable air pump to inflate tires. However, the ring terminals on the cable do not even reach near the battery terminals. I don't know if there are batteries with smaller terminals, but it looks like this product doesn't connect directly to a typical car or RV battery. Instead I cut the wires under the built in fuse and connected the wire to the 12V DC fuse panel. The fuses that come with the cable are a perfect match for my WFCO panel.
