Turn your 30-amp shore power plug into a SmartPlug cordset by clipping off the inlet end of your power cord and wiring in this new connector. Plugs in without twisting and locks in place with side clips.

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:
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.

Hi, everyone, Jesse here with etrailer. Today, we'll be taking a look at some of SmartPlug's products. We'll talk a little bit about what they are, why you would use them, and what's the right setup for you. The SmartPlug is essentially just a much-improved way to plug your shore power into your RV or your boat. You're probably used to the classic twist-lock version, which known to fail. It's a very big failure point on RVs and boats, and what I mean by failing is, these prongs will get loose or there's a plastic collar that you have to thread on here.
Sometimes people will cross-thread it, just ruin the threads, or that collar will break off. I've seen a lot of RVs come in with their shore power having obvious hotspots or even melted plastic. So, that's a safety concern, and that's where SmartPlug comes in. Our neighbor today has a newer trailer, but they're already sick and tired of dealing with the twist-lock connector. And if you have any experience with it, you know how big of a pain it can be.
You have to get it perfectly lined up, and then carefully thread on that plastic collar. Whereas with the SmartPlug, you just lift the lid, I'll unplug it. And here's a look at our shore power cord. You can see it has a blue LED light on it, makes it very easy to find. It can only plug in one way, and it just simply slots in.
You'll hear it lock on both the tabs here. And the lid here will keep it from being able to pull out even if those tabs aren't engaged. So, our neighbor's trailer has a 30 amp inlet, which is one of those things that you'll need to know when you're shopping around for your SmartPlug, whether you have a 50 amp system or a 30 amp system. A smaller trailer like this, most likely going to have a 30 amp, but whenever you get into your bigger rigs with multiple AC units and a handful of appliances, that's when you're most likely gonna have 50 amps. So just make sure you know that before you purchase the kit.
But either way, SmartPlug has you completely covered, whether it's 50 or 30 amps. You're gonna have a range of colors, whether it be gray, white, black, or even stainless steel. And once you have your inlet sorted out, you can move on to figuring out which shore power kit is right for you. SmartPlug offers many different lengths in both 30 and 50 amp, and they even have different connector styles. As you can see, this is just your standard straight pull. And this one, I actually prefer the 90-degree right angle on because it's easier to unplug and plug back in. Or if you want to retain your old shore power cable, 'cause there's no use in throwing away a perfectly good cable, they have connectors, which you can adapt your current shore power cable into a SmartPlug cable. SmartPlug even offers a cable in case your outlet for your shore power where you're always camping or boating is a twist-lock style. So they really have you covered no matter what style shore power cable you really need. The SmartPlugs aren't just safer and easier to use because of the design. It also comes down to the materials that they're using. I've been reading a lot of neighbor reviews that mentioned that these are very robust and they seem to just hold up to the test of time. And that's because these are made in the USA and they're made of high-grade materials. As I said, the plugs here are marine-grade stainless steel. They have a high-quality plastic that's gonna hold up to UV rays and heat, and everything is rubber sealed to keep any moisture out of there. We're also seeing a lot of RV and motorhome manufacturers just putting SmartPlugs on there straight from the factory. So I feel like you're gonna be seeing a lot more SmartPlug in the future. If you have any questions or concerns after watching this video about what you need to get for your setup, feel free to reach out to us. We'd be happy to get you pointed in the right direction. And also, I know when it comes to electrical stuff, it can be kinda scary to install, but really, it's a pretty simple install. They even have it color-coded for rewiring it. On our neighbor's trailer, it was just a matter of unhooking their old stuff, and then wiring up the SmartPlug and bolting it up. It didn't involve any custom work like cutting or filling holes at all. But if it's not something that you feel comfortable doing yourself, check out our dealer locator. You can find someone local to you. I'd be happy to get you set up. But anyways, I hope this video helped you learn a little bit more about SmartPlug and why you might want to upgrade your rig. I'm Jesse, thanks for plugging in.

Great service
Great service
Very solid!
Fast shipping order arrived as described A ++++++
Instructions ok. Used to reuse old trailer cable as a spare.
High quality
Got sick of trying to start that nut on old cord this one you push in on and it locks on. Simple to install and way simpler to use.
This is a very robust plug. Assembly was fairly easy following included instructions. Has a secure, tight fin when plugged in. Would buy again.
Great love the product
Service and product were great. Highly recommend.
The SmartPlug product is very well made. Great product. I had an older 30A RV cord that was likely a bit thicker insulation, so the rubber boot was extra tight, but was able to make my backup cable for my RV just fine with following the directions using soap.
I needed to convert my 30 amp home shore power cord to the Smart Plug for a new RV. This is just what I needed. It was a little hard to find on your website, but perseverance paid off as I was sure it was available alone, not just as part of a complete kit. The instructions look easy to follow. The shipping was unbelievably fast. I ordered on Saturday morning, was promised Tuesday delivery, but received it before 10:00 AM Monday!
This is a USA made SmartPlug of exceptional quality and workmanship. Nothing cheap about it, a very robust connector. Just use soap as they recommend for the rubber boot. A lubricant of oil or grease doesn’t work as well as soap.
Customer service is fantastic and Lauren is extremely helpful
More secure and easily installed
Perfect for adding smart plug to dog bo ne.
The instructions were written very small for these old eyes but the job got done. Simple job if you know the difference between a wrench and a screwdriver. Highly recommended.
Easy to order, absolutely on time. I'm going to use e trailer for my rv needs
I realize this is somewhat of an aftermarket product. The reason I bought it was that I drove away from my home with the rig plugged in, dumb move, right. I am disappointed it does not have the blue current indication light. I ordered new one from the company and it has an angled female end so the cable hangs straight down instead of sticking out. I have replaced the end on my old cable and use it as a backup.
Very nice water tight plug assembly. You need the male inlet that mounts to your trailer as well. Both fit together snuggly to make a sealed connection. The chrome latches on the side secure this plug to the male side. Expensive, but when a cord cost $85.00 to replace this does not seam that expensive. I had 2 cords melt due to rain water shorting them out. Luckily, I didn't burn my RV to the ground.
Easy to install yourself with a box knife, a screwdriver and wire strippers. Tools anyone should have when in an RV.

Definitely will recommend this plug to friends and family. Tighter and more secure fit than the factory plus.
