Expand Your Shore Power Options with Confidence

The M1A2 Marine & RV 30A to 15A adapter bridges a common shoreline mismatch: a 30A twist-lock inlet pairing with a standard 15A outlet. Built for outdoor use, it uses UL-certified copper conductors and a flame-resistant PVC outer sleeve to help maintain a safe, durable connection. This unit accepts applications at up to 125V/250V and is rated for a maximum of 3750 watts, keeping real-world power needs in mind for campgrounds, marinas, and boat docks.

Key features include a twist-locking female connector with a threaded ring that locks into place, helping resist accidental disconnection in breezy conditions. The ergonomic handle is designed to reduce fatigue and improve grip during setup and teardown, making a routine maneuver feel less cumbersome even after long days on the road or at the slip.
