Best Quality adapter: Parkworld Marine Plug adapter

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate adapter. The parkworld marine plug adapter is exactly that - it's a simple adapter that hits all the right notes. As an electrician for over 45 years, this unit makes a safe and up to code installation on a houseboat for shore power connection. It has a heavy-duty power adapter cord for rv / boat / marine shore power inlet pedestal. The supplied locking rings and connector at the 50 amp end is a real plus.

The limiting factor is the circuit breakers in the dock power pedestal, they are only 30 amps. You can use it on yacht or rv marine style power inlet on pedestal. It allows a 50 amp cord to connect where only 30 amp connectors are available. These breakers will trip if you try to exceed sustained 30 amps.

Best For RV environments: Marine Plug adapter

The marine plug adapter gives the top-tier adapter a run for their money by offering flagship specs at a much more affordable price. It works well and provides flexibility for shore power connections on a boat. It allows you to split one dock side receptacle between two boat inlets of similar or dissimilar power configurations. The built in light is an awesome addition.

This is a high quality electrical connector that splits a 50 amp service and splits it into 2 30 amp connections. It is built for the harshest environments and is UL approved. The little LED lights are very handy as well, allowing you to not have to return to the power pedestal to double check that it is on a boat. It fits snugly to the outlet to add to the features and is very helpful.
