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 - Replacement White 30 Amp Power Inlet - SM57FR

Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at this smart plug replacement, 30 amp RV power inlet. This is going to replace your smart plug inlet so that you can get your RV hooked up to your shore power. Again. Now this is a white 30 amp 125 volts, male inlet.

So it will accept your 30 amp female connector will plug right in there, click in. So it's nice and firmly connected. Now this is the connector is sold separately. So if you are just wanting to replace the inlet this is a great option for you. If you're wanting to switch over from an older style twist type inlet I would recommend maybe going with one of our kits available [email protected]

It comes with the cable and the inlet. So it's going to help you convert your whole setup rather than just the inlet because you will need a connector that fits in there because this is kind of a proprietary design. So it will only fit into one way. But if you are looking for a replacement for a smart plug inlet that you've already been using and this is going to be a great option for you this is the white option. There's also a gray, a black and a stainless steel.

So you want to make sure that you're getting the one that works for your color scheme and a RV setup. This is going to be very easy to get installed. They do include instructions with pictures to help you every step of the way. They also include a hex key to get those wires tightened down so that they're going to have a nice firm connections of the adhesive foam gasket is included as well, so that you have a nice firm connection on the backside there. So everything that you're going to need to get your original smart plug replaced is going to be included in this is going to have all the same features as that original.

It's going to have the straight nickel plated brass inlet pins. So you're going to have a maximum electrical transfer going back and forth or coming in from your short power. It does have the sleeve design. So it's going to keep the weight off those pins. So if you we're to trip over your quarter or something like that, those aren't going to get jostled become loose. This is going to have that straight on connections. So it's going to be very easy to plug in and even in the dark, it only goes in the one way. You're going to have the weatherproof seal preventing water from getting in the inlet cap does have that weatherproof seal there. That's going to snap closed and create that nice waterproof closure there when you're not using it. And then the cap will also close down onto the connector when it's plugged in to help give it an extra little bit of resistance from pulling out. This is constructed of a plastic resin that is UV and heat resistant. So it's going to be very durable for you. It's made here in the USA, so you can trust. It's made to the high quality standards that we've come to know and trust for products that are made here in the U S so if you are looking for the 30 amp white inlet for your smart plug system, this is the way to go. Like I said, if you're wanting to switch your whole system I would recommend going with one of the kits and we also have other colors available if you would prefer one of those other colors. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..

Review from a similar SP Power Inlet in RV Power Inlets


I was having issues with the electric connection at the trailer. The ring around the male plug wasn't keeping the plug right to the trailer causing a couple lower outages in the trailer. This plug combination totally cured that issue. When plugged into trailer, it's a tight positive, locked fit. When electrical connections are loose, they cause heat. Could very well cause a fire. I eliminated that connection problem with this plug!!!! Highly recommend.

Review from a similar SP Power Inlet in RV Power Inlets


I Just installed this today. This plug is awesome! It is part of my mouse proofing project. Mice were coming in thru the the old cable opening. That is another story. The directions on this were easy to follow and clear. I didn’t think my cord would fit in the strain reliever but with enough soap it did. The only suggestion I have is that they include 4 stainless screws to fasten it to the camper. My only regret is not doing it sooner.

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
