One of the most useful devices we carry in our RV tow vehicle SEEMORE is a 12V socket duplicator. What is a socket duplicator? It’s a little adapter cable that gives us more “cigarette lighter” 12V charging receptacles.
These days, it seems we’re always charging something like a phone or tablet. Then there’s our GPS, which requires 12V socket power. We also carry a radar detector.
With a socket adapter, we have all the charging recptacles we need.
I like the XTG socket adapter, because it not only includes FOUR 12V sockets, but also a USB charge socket (for phones and tablets).
If you travel extensively, you need a socket adapter! ‘Nuff said.
