One Piece Adapter with a 15 or 20A 125V Straight Blade Connector and a 30A 125V Locking Plug

Straight Adapters are high-quality, one-piece adapters similar in usage to Pigtail Adapters. However, they do not have sealing collars and are not recommended for use in wet locations. Use only in an enclosed, dry location, such as powering your boat from a 15A power receptacle inside your house.
