The 5 Best Marine Y adapters (2023 reviews)

Compared with other adapter in this category, the marinco extension cord has a design with broader appeal. This cord is intended for adapting a 30amp twist lock connection (on your RV or boat) to a standard 20amp 120v outlet via an extension cord. The Flexibility of the 110 side is a far superior design to the fixed adapter type shore plugs. This one is awesome and the cord is super thick.
