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.

  • Is SmartPlug 50 Amp Female Plug Assembly Available By Itself
    Thanks for reaching out, Glen! To get the plug side of the SmartPlug RV Power Inlet - 50 Amp # SM56FR you were looking at, you just need the 50 Amp Female Plug Assembly # SM36FR.

  • Does the SmartPlug RV Power Inlet Require a Special Cord to Connect From Shore Power
    Yes. In order to use the SmartPlug Replacement RV Power Inlet - 50 Amp # SM56FR you will need to replace your old twist lock power cord with a SmartPlug RV Power Cord - 125/250V - 50 Amp - 30' # SM86FR.

  • What is Max Wire Gauge that Can be Used with SmartPlug RV Power Inlet # SM56FR
    Hey Wayne, so SmartPlug recommends that you use 6 gauge wire with the SmartPlug RV Power Inlet # SM56FR but they don't list a max gauge. I would just go with 6 gauge and you'll be good.

  • Does etrailer Offer Any RV Power Cords Made In The United States
    Yes, the SmartPlug line of power cords and all of their other accessories are all made here in the United States. Since you were looking at a 50 amp power cord you would need the SmartPlug RV Power Cord - 50 Amp - 30' # SM86FR along with the correct power inlet. Since you have a 2018 Airstream Flying Cloud Travel Trailer you'll most likely want the stainless steel inlet # SM79FR, but we also have a few other color options if you'd like: Black # SM56FR White # SM89FR Gray # SM29FR

  • Where Are Mighty Cord Power Cords Made?
    The Mighty Cord RV Power Cord # A10-5025ED90 is made in China. Don't let this discourage you though. This is a well built and sturdy power cord and I have not had any issues with their products brought to my attention. That said, if you are looking for American made products, we do have the SmartPlug line available. The SmartPlug RV Power Cord # SM86FR would be the most similar to the Mighty Cord you were looking at, but SmartPlug uses a proprietary male port so you would also need to...

  • Power Inlet Needed To Add Shore Power To An Enclosed Trailer
    If you're only wanting to setup AC service in your enclosed trailer then you could choose pretty much any 30 or 50 amp power inlet you wanted and then just run the appropriate gauge wire between the inlet and your panel. You can definitely install a 50 amp inlet and then just use a 50 amp to 30 amp adapter whenever you're at a site with only 30 amp service. You could use the Mighty Cord Replacement RV Power Inlet - White # A10-50INVP or # A10-50INBKVP for black. You'd need a minimum of...

  • Recommended Smart Plug 50amp RV Power Cord to Work w/a 30 amp 240V Generator
    Hey Pat, congrats on your new trailer. Since you're converting over to a 50 Amp SmartPlug RV Power Inlet like item # SM56FR, you can use the SmartPlug Marine Power Cord Adapter - 50 Amp Female to 30 Amp Male Twist Lock Connector item # SM43VR This 4' adapter lets you connect your 50-amp SmartPlug cord to a 30-amp twist lock. It is only rated to 125 volts though. We also have the SmartPlug RV Power Cord - 50 Amp - 30' item # SM86FR and the Angled RV Power Cord - 50 Amp - 30' item # SM54SB....

  • Is Box Needed To Install SmartPlug RV Power Inlet?
    All of the SmartPlug RV Power Inlets such as the # SM56FR you were looking at attach directly to the exterior wall of your RV, and there is no box compatible with them. I included a video of this plug being installed for you to take a look at.
