SmartPlug - Innovations in power delivery

SmartPlug power products are made in Seattle using the highest quality materials. Our products are known for enhanced safety and ease-of-use. The unique and patented design features include self-alignment (asymmetrical plug shape & no L-shaped pin), push straight-in connection (no more twisting) and superior thermal performance (eliminates overheating due to increased metal-to-metal contact).

SmartPlug power products are designed to meet or exceed all US Marine UL, Canadian CSA and European CE code requirements. Our products come with a 7-year warranty which exceeds the industry 5-year standard.

The Problem versus the Solution graphic

Contrary to popular belief, the #1 cause of shore power failure and fires is not electrical shorting, but rather overheating caused by poor electrical conductivity. How does this happen? The problems with many plug designs are that the shape of electrical pins allow for very little contact area, and the pins themselves are also largely responsible for bearing any physical stress placed on the cord (from constant movement of the boat, someone tripping on the cord, etc…) This results in the pins working loose, further lessening the precious little contact area they had to begin with. Furthermore, such loose connections allow for moisture intrusion and ultimately corrosion of the pins. Arcing occurs and the connection heats up, scorches, and in some cases, catches fire. Because the current draw is unchanged, all of this happens long before a breaker or a GFCI can cut the power. Additionally, the old design can be very difficult to use in low light or hard-to-reach scenarios since the “L” shaped pin must first be located and then oriented before connection.

SmartPlug’s 4-Stage solution protects against overheating every step of the way. Loose connections are addressed by a Sleeve Design and Multi-Point Locking System which take all the physical stress off of the pins while securely fastening the plug to receptacle. Pin contact area is increased by more than 20x and protected behind three weatherproof seals for a dry and corrosion-free connection.
