SmartPlug vs. Twist Lock


RV and boat owners have long relied on Twist Lock style connections for powering their rides. For years, it has been the best option for connecting to shore power. It's been reliable, but most know it's not without disadvantages:


Twist-Type Design Problems

  • Curved pins make minimal surface contact, increasing the amount of heat generated
  • Locking ring can be prone to breaking, cross threading, and stripping out
  • Faulty locking ring puts strain on the connection
  • Wear and debris can loosen the fit, further decreasing surface contact
  • Circular plug shape isn't user friendly and takes some awareness of the orientation of the pins to insert correctly

SmartPlug's connector addresses each of these concerns and does all of the heavy lifting.


Locking arms grab the inlet, a clamp inside the plug body holds the cord, the inlet cap snaps to the top while in use, and the integrated seals weatherproof the connection. This helps prevent the wiggly, dirty connections that increase electrical resistance, which creates potentially dangerous heat.


Since it uses a square plug face, SmartPlug is able to use flat pins which create far more surface contact, further reducing the risk of high heat and electrical arcing. The square shape and flat pins also make it easy to plug in - no more twisting or guessing if the pins are lined up correctly.

Review from a similar SP Power Inlet in RV Power Inlets


I’ve been using a smartplug for three years now. It’s been amazing and has outlasted the old twist lock style. My connector still looks brand new. But I ordered this to upgrade to the stainless housing since the plastic one became brittle. It’s worth the extra money for stainless! And this is the best price I found for them.

Review from a similar SP Power Inlet in RV Power Inlets


I haven’t had a chance to install the smart plug power inlet and connector yet but based off of videos and reviews I have no doubt it will be huge improvement from the twist lock and plastic wring I currently have. Will update again once installed
