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.

Very good product. Works well and cord is nice and flexible allowing for easy stowage. I like the clip on female plug instead of the screw ring. A lot easier to connect and disconnect.

I purchased Smartplug RV power cord and inlet to use with my race trailer and I really like it. The quality is great, and the technology is fantastic. The plug is so much better than the old RV twist plugs. The only downside is the cost. What I really like is the customer service from etrailer is fantastic!



by:

We chose to change to this product because the "pull out" shore power line that came with our RV got hung up inside the compartment and took considerable work to get out. The SmartPlug system was an easy install and the stainless steel inlet is very high quality. I really like the led indicator lights that confirm the incoming power is properly wired. The power cord has quality plugs and securely attaches to the RV.



by:

etrailer was easy to work with. Order process was smooth and delivery was timely. The SmartPlug RV Power Cord - 30 Amp - 30 ft was well priced and received in good condition. The item is definitely well made and durable. It even came in a nice storage bag. I look forward to years of trouble free usage on my adventure vehicle. Based on this experience I would recommend etrailer to anyone looking for similar products.

VERY FAST ON DELIVERY! ALWAYS COMES THROUGH WHEN I NEED SOMETHING! :)

I replaced by 2010 Airstream's inlet and cord with the SmartPlug. Installation was simple and took only a few minutes with simple tools. I enjoy the peace of mind of knowing that fire risk has been diminished. Highly recommend this product.



by:

I already had the wiring on the old box on the rv disconnected. When the new one came today, I had it mounted and completed in 20 minutes. Alot better than the old twist on one that gave us trouble since we bought the rv new in 2023

  • 50amp SmartPlug Cord Package Contents
    The SmartPlug RV Power Cord - 125/250V - 50 Amp - 30' Item # SM86FR does not come with the smart plug RV receptacle. If you need the receptacle we offer the SmartPlug Replacement RV Power Inlet - 50 Amp - Gray Item # SM29FR

  • Best 50 AMP 125/250V Power Cord For Your Camper
    I have a power cord which is the same thing but more so what you're looking for. This cord is rated for 125 and 250V unlike the one you were looking at. The SmartPlug RV Power Cord - 125/250V - 50 Amp - 30' Item # SM86FR is rated for 125/250V. This will last longer than the cord you were looking at in my opinion. I've included a similar video to the one you watched so be sure to check that out to learn more about the cord!

  • 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

  • Is The 50Amp SmartPlug RV Power Cord Available Is Lengths Under 30'?
    Currently SmartPlug only offers their 50 amp cord in a 30' Length # SM86FR. We do have a Replacement End # SM36FR you could attach to a 50 Amp Power Cord # A10-5025END. This particular cord is 25' but you can cut it down before adding on the SmartPlug end.

  • Connect 50 Amp Service Airstream RV To 15 Amp Outlet For Storage Charge Of Battery
    For use with a 50 Amp SmartPlug RV Power Cord, such as # SM86FR. I recommend the Mighty Cord RV Power Cord Adapter, # A10-1550. Connect your SmartPlug Power Cord to the RV as usual, but then plug into the Mighty Cord adapter for making connection to a 15 amp outlet when in storage.

  • 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...

  • Parts Needed To Convert An RV From 30 Amps to 50 Amps
    You can upgrade your setup from a 30 amp to a 50 amp but it's going to be pricey and you're likely going to need to hire an electrician. The first thing you're going to need is to swap out your 30 amp inlet with the SmartPlug RV and Marine Power Inlet # SM79FR. This is going to require you to replace the existing wiring as well to accommodate for the extra amps. You'll also need a new control center, Progressive Dynamics 4500 Series RV Converter w/ Charge Wizard and AC/DC Distribution...

  • Will Swapping A Trailer From 30 Amp To 50 Amp Service Affect The Value Of The Trailer
    Typically two AC units running at the same time is going to have such a large power draw that you'll need to have 50 amp service so the trailer should not have had two units with only 30 amp service equipment. To complete the swap over you'll need a 50 amp power cord, 50 amp receptacle, and a power center rated for 50 amp service. The answer page you were looking at from Dave that listed out the SmartPlug # SM79FR and # SM86FR along with the Progressive Dynamics # PD4590K18LS8 are all...

  • Replacing SmartPlug With Standard 50 Amp Inlet
    There is not an adapter to go from the SmartPlug to a twist-lock power cord, so what you'd have to do is replace the SmartPlug inlet with a standard 50 amp inlet, the Mighty Cord Replacement RV Power Inlet - Twist Lock - 50 Amp - White # A10-50INVP or Black # A10-50INBKVP. That would allow you to use a standard 50 amp power cord like the Mighty Cord RV Power Cord - 50 Amps - 25' Long # A10-5025ED90.
