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.

Video Transcript for Review of SmartPlug RV Power Inlets - Power Inlets - SM29FR

AJ What's up, everybody, it's AJ with etrailer.com. Today, we're gonna be checking out the SmartPlug replacement RV power inlet, 50 amp, and the color is gonna be gray on this one. Is gonna replace the plugin on your rig. So you probably have the plug in and twist version, and there's some issues with that. It's not exactly waterproof. It does overheat from time to time.

There's a lot of stress on the cord, too, hanging out there. This addresses a lot of those. I know I had issues with the push in and twist version, just because sometimes you can't line up quite right and you go to turn it or tighten it down with one of those rings and it just won't tighten up. You can't seem to get it, especially at nighttime, when you go to put it in there, you might not be able to see it right away. You can see these problems are fixed on this one.

It's got a specific shape to the plug. So you can match up that cord for this plugin in very easily. Now it doesn't come with the cord, you'll have to get that separately, but this is just converting your rig to this system. The system works really well. It's got triple weatherproofing.

The straight pins there on the inside are way better, make a far better connection. Actually, with this connection, it's 20% more contact than the curve design, so this is gonna get more power through there and be safer about it too. I like it 'cause you can line up and plug in on the first try, even in the dark, you know. Okay, match the shape, plug it in. You got a seal on the top here.

It's gonna further protect it. It closes very well, I've got it right there. You see, I can't just open it with my hand easily. You kind of do have to get in there, open it, so I like that that sturdy cover's gonna stay shut. It's gonna be really easy to install, too, and replace your old one. So you can see it's color-coded here on the back. You're gonna match up those wires with the one on your rig side already. When you remove the old cover, strip back those wires, you'll connect those in there. Comes with the Allen wrench to tighten that down on each side, so here, here, here, and here, and that'll hold the wires nice and tight and keep them in place. You push this back onto your rig side with the gusset here on there. And once it's on your rig, you'll use the existing hardware you use to remove the old inlet, to install this one and you're good to go. It's pretty easy to install. It makes it very easy to use, too, just that straight plugin. Also takes some stress off the cord that, like I said, the other twist-in one hangs down there, this one has a sleeve design so it's gonna go in here, hang out a little bit more. And then the stress will actually be on the part here rather than on the cord that's hanging down. That about does it. Thanks for hanging out, and I hope this helps..

SmartPlug RV Power Inlet - 50 Amp - Gray - SM29FR

Average Customer Rating:  4.8 out of 5 stars   (132 Customer Reviews)

Get your ride SmartPlug ready. Replaces the fiddly twist lock inlet with a more secure and safe connection. Plug in with ease and have one less thing to worry about. Installs into the same footprint as a standard inlet with no modification needed.

by:

The old style RV plugs are prone to have connection problems which causes melting of the unit. That happened to me in below freezing weather and we lost power to our trailer. This new plug will not have that problem. It fits together solidly and I don't worry about any loose connection. I have seen that the SmartPlug is now standard equipment on Airstream trailers. That's quite an endorsement. You Cann't go wrong with the SmartPlug system.



by:

I have on several occasions experienced times when my electricity inside our RV wasn't working. It would inevitably be because the connection from shore power to the camper was loose. I just installed my new SmartPlug today and already feel confident in the connection. Purchasing from etrailer was easy and the product shipped in a timely manner.



by:

When saw this of course I said I wanted it. This make hooking up a lot easier and I feel more secure about the electrical connection. Now my friend wants me to change his. The conversation was very simple.



by:

etrailer kept me in the loop on the backorder of the black SmartPlug, I understood the supply chain, but it was nice to be updated on the timeline for shipment. So nice for a company to keep you in the loop without having to chase the details!



by:

No complaints. Got what I ordered, installed it and it worked. SmartPlug 30amp white.



by:

I really like the SmartPlug! I kept noticing the old plug would turn sometimes in the socket and just about unplug itself. The SmartPlug is always secure and easy to unplug when you are ready.



by:

The Smart Plug is a quality upgrade to our Airstream. It looks good and was an easy quick install.



by:

Excellent customer service on the part of eTrailer. Had to exchange the stainless steel model for this one because of fitting issues. Product itself is well constructed and exceeds intended purpose!



by:

I found the installation of the inlet easy and the modification of the connector very easy. The instructions were very easy to follow and very comprehensive.

The only issue was the rear cover (pictured) for the inlet could not fit at the front location of may 2019 Airstream Flying Cloud 27 ft. FB. I also installed the cable port.



by:

Superior to all other shore power inlets! This system is amazing.



by:

Easy to Install. Clear instructions but you can also find install videos on YouTube. Stainless cost slightly more than the plastic version but looks great on my Airstream.



by:

The SmartPlug installed great and after a year of heavy use continues to perform perfectly! Electrical hookups are now quick and positive with solid connections!



by:

E trailer is my go to shop for many of my components and appliances in my Van Builds. Their prompt delivery and customer service is excellent. Their consistency is something I can depend on Van to Van to Van.



by:

I received at least two emails updating me on the shipping dates and another one when it shipped. The Smartplug was on back order and they kept me up to date.



by:

It's installed but still building trailer so have not gotten to use it yet. Will Update when i do!



by:

Can’t wait to get it installed. Looks like quality materials and ease of installation per videos.



by:

Delivery was a few days later than it said at first. Otherwise, product was what I ordered. No hardware sent with the inlet which was frustrating, why on earth wouldn't the company include the mounting screws?! Works fine otherwise.



by:

I had been looking at this plug for awhile before I bought it. I was living full time in my camper. And my old twist style plug kept blowing the breaker on the power box. Bought this to replace it. No problems at all cents then. Love it. Easy to in stall.



by:

Excellent product. Install was not difficult. .definitely an upgrade from the original 50 amp plug.



by:

Excellent part, excellent customer service and support. etrailer is my go to for parts.



by:

This is a very well-built and designed product. I love the fact that it snaps securely to the inlet, and that the inlet closes securely when not in use. I got this to replace the mouse door that typically comes on campers (a huge hole port with a door that leaves a large gap while the cord is in use!). Keeping mice out is worth the price already, and this is a much better quality connector than I usually see on campers these days that use the detachable twist-lock type cords. Still working great after a year of use.



by:

This is a very welcome improvement for our RV's Electrical hookup. Easy to install, took about an hour.
One concern, the connector instructions that I downloaded stated to cut back the cable outer jacket 1.25". The instructions that came with the connector stated to cut back the cable outer jacket to 1.75". I feel the 1.25" was correct. 1.75" does not really give you enough exposed outer jacket to achieve the required 1/4" grip by the cable clamp swing arm.



by:

very high quality and easy installation.



by:

Easy to change cord plug. Outlet was a bit challenging as I couldn’t get wires pulled out far enough, so had service center do that part. It’s a little hard to push all the way in so side latches catch; but top latch secures.



by:

The quality of products that etrailer provides, as well as the pricing are just two of the reasons I shop here first. I have found it’s the rare circumstance that etrailer may not carry an item I’m looking for. In most instances it’s because the manufacturer is behind on shipments or their inventory. They have provided a great service and I’m a very happy customer.

  • 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...
