Easily replace your inlet and rewire your power cord for a SmartPlug connection that is both safer and easier to use. This package contains everything you need to upgrade your ride for a new generation of shore power connection.

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.

Ratings & Reviews
Installation was straightforward and its a really strong connection....simple plug it straight with no twisting...snaps in place and stays in strongly....simple press the side tabs to release easily.got it all done in 1 hour on my 2021 salem hemisphere
great product and easy install
Efficient, strong and will last a long time
Can’t wait to get it installed. Looks like quality materials and ease of installation per videos.
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.
Nice change on my Sprinter van.
Good product and clear instructions. It is much better than the twist connector.
Great product It is already on my Duffy and putting it on my RV now
I like the way it plugs in and snaps in place
Love the idea. But I had to buy three new socket screws to tighten the wires to the back of outlet. The cheap screws that came on it were shallow and loose on every Allen wrench I tried. Bought new 1/4-20 x38 stainless screws $[XX]. At $[XX] one should not have to buy new parts to be able to tighten them properly.
Unit is well made BUT does not fit into most Airstream trailer models (too deep) should include a notice to that effect. Had to leave off the back-end cover to make it fit...and it was tight
The power adapter is awesome once I got it installed. It is easy to plug in and unplug. My wife always hated the plastic screw ring on the old plug. It wanted to cross thread all the time. Is it worth the money? I think so. My wife does lots of traveling by herself and this gives me peace of mind that one of the potential fire problems is now gone. We replaced the old plug because it started to melt at the hot terminal. Turns out the trailer side wire terminals were never tightened. My experience wasn’t all roses though. The order was shipped via USPS and got lost for a couple of days. When it did arrive, the new plug was missing one of the set screws. I had waste time going to the orange box store to get the needed set screws. Etrailer is not directly responsible for either issue, although they could probably stop using the postal service. The other part I ordered was lost even longer and showed up almost a week later.
Overall I am happy with the SmartPlug. If I ever get a different RV, this will be one of the first upgrades.
Installation was a breeze. Will try it out this weekend!
Product is as described product was shipped on time. Installation was easy

Thanks for taking the time to share your experience William. Glad hear the Smart plug is good quality and I can definitely understand your frustration with the fitment. The SmartPlug is designed to replace many standard 30-amp inlets but the deeper housing can make it a tight fit on some Airstream models. I really appreciate you calling that out, as it's the kind of detail that can help other Airstream owners before they start their installation. which year and model Airstream are you installing this on? We'd like to know so we can better assist those with similar setups.
