Most shore power fires are caused by poor electrical contact and overheating in traditional twist-lock plugs. SmartPlug solves this with a straight-in design that provides 27x more contact surface area, ensuring a cool, secure connection every time you plug in.
From the open ocean to the open road, SmartPlug provides a superior power connection that prioritizes safety and ease of use. Discover our specialized solutions designed to protect your vehicle, your equipment, and your peace of mind.
SmartPlug replaces outdated twist-locks with a secure, intuitive system built on marine-grade materials and maximum contact technology — designed for the modern mariner and traveler.
From marine-grade stainless steel to high-impact resins, every component is selected for its ability to withstand extreme UV, salt, winter, and heat performance that never scales back.
See why thousands of boaters and RV enthusiasts have made the switch to one of the most trusted power connection systems available.
I used to struggle with traditional twist-lock plugs, especially in low light or tight spaces. With SmartPlug, it's a simple push-in connection every time — no guesswork, no hassle, just plug in and go… The locking collar gives an audible click when it's seated correctly, so I always know the connection is secure before I walk away from the dock.
The peace of mind is worth every penny. After seeing a traditional twist-lock melt on the dock next to me, I upgraded to SmartPlug immediately. The connection is rock-solid, even in heavy storms… I've since recommended it to every boat owner in our marina, and the ones who've made the switch haven't had a single connection issue since.
After years of working with marine insurance claims, I've seen how dangerous traditional shore power connections can be. SmartPlug stands out as a safer, more secure solution… It's one of the few upgrades I actively recommend to boat owners looking to reduce their risk of an electrical fire or claim.
