I thought not having to bend my smart plug power cable in my little power compartment on my airstream atlas would be a good thing so I purchased the angled power cord. It is a bit more difficult to put it into my compartment and is a struggle to close the little plastic compartment door around it. Tine will tell if not having to bend the power cable prolongs the life or not. At this point, I would not repurchase knowing what I know now.



by:

Same thing applies to the 2nd item ordered. Exceptional delivery time is greatly appreciated



by:

Just what i needed.



by:

The angled head makes this really a great power cord. All the difference in crowded spaces, even if it’s just me moving around the trailer.



by:

Nicely made heavy duty



by:

Of course great quality. You get what you pay for. I didn't want to purchase because of the high price tag but I believe its worth it. The 90 degree handle sold me. Take the pressure off of the cord.



by:

I like the new design. Less stress on the trailer plug in.

I'm giving this Smartplug cord and the Smartplug male trailer wall socket a 4-star rating, but not because the product isn't EXCELLENT. IT IS! On this 2-week camping outing, we have nearly lost our 37-ft. Rockwood Signature travel trailer TWICE to fire, due to the common, everyday 'Twist LOC" RV socket and matching cord overheating while operating our 50-amp trailer on 30 amps (coming between 2-3 amps of 30 amps, but not OVER 30 amps.) The standard 50 amp female power cord end and male plug installed into the side of the trailer MELTED while running on 30-amp service, drawing 26 to 28 amps continuous when both A/Cs were cycled on at the same time. Neither the cord itself nor the trailer's power feed cable ever got hot--ONLY THE CONNECTION where the power cord and trailer plug MEET. It nearly started a fire in the rear wall of our trailer. Melted wall insulation, charred the edges of the fiberglass siding and nearly burned the underlayment underneath the skin. Fortunately, it was NOT a wood product. Both the female cord end and the wall connector plug were melted and charred. Both were replaced by the mobile RV tech who does all of our RV work (I am disabled.) The new cord and trailer plug then melted again 24 hours later. I ordered this Smartplug cord and trailer plug from etrailer and got it in 4 days. Since new Smartplug cord & plug were installed, I am still pulling 25-28 amps when both A/C compressors are running, but I can feel very little heat on the outside or inside (where the trailer wiring is run into the wall), and the highest temperature I've recorded with the laser temperature gun is 102.5 degrees (high air temperature has been 95 degrees). PROBLEM SOLVED!! The only reason I gave these Smartplug items 4 stars is because of their COST!! The 30ft. Smartplug trailer cord and accompanying male trailer wall socket cost me $718!!! That's pretty close to RIDICULOUS!! They DID, however, SOLVE MY OVERHEATING WIRING CONNECTION PROBLEM!! Read the Smartplug ads and watch their YouTube video from etrailer (can be reached on etrailer's website). THEY AREN'T LYING!! Smartplug saved our very expensive RV!!

Oh my! I am very glad everyone is okay and nothing or nobody was harmed in a potential fire. It is great to hear that a solution was found and you haven't had to worry since. I can agree on the price but it sounds like it was worth it for not having that fire issue any longer. What kind of RV do you have?

Our travel trailer is a 2020 Rockwood Signature 8328SB. The Signature models are Rockwood's most "upscale" offerings, with actual La-Z-Boy brand swivel/rocker/recliners, Serta mattress, hidden hinges, self closing drawers, etc. At 37 ft. long, the 8328SB is a fifth-wheel floorplan on a conventional travel trailer frame, with a huge front clothes closet streetside and washer/dryer closet/compartment on the curb side (and a very large outside storage compartment underneath the clothes closet), built on a conventional travel trailer platform, with a flat floor inside from front to rear. NO STEPS. That makes it much more convenient for senior citizens such as ourselves.

@JimB That sounds like quite the rig! Definitely something you do not want burning up. Are you full time in it?

@NickS No, we aren't full-timers. But we do try to camp with our RV about 2 weeks out of each month from March to November. I was disabled at the age of 39, 35 years ago, so my wife, although at retirement age, must work if we want to continue to support the RV and a diesel GMC to pull it, and pay the camping fees. Our local Texas U.S. Army Corps of Engineers lake, Lake Whitney, is only 17 miles from home, and while we are camping, my wife (and her sister with her nearly identical RV) must continue to commute to work each weekday. But they both still love it. I schedule the site reservations to include 2 weekends on each trip, which gives them both time for some "real" R&R while we are out there. I had never RV camped until we were married in 1974, but she and her sister have been RV camping since they were a couple of months old, in 1952 and 1954, sleeping on straw in the back of their Dad's pickup. Since she must continue to work, and my wife loves RV camping so much, being the "financial nerd" I always make sure that I arrange our budget so that we can afford the recreation that she craves. We are both well aware of the fact that our health my force some changes ahead, or require that we give up RVing altogether, but we are determined to enjoy it as long as we can, which is why she's still working. We only go further than our local lake about once a season, but that suits her just fine. My job is to keep her happy!!

Easy installation of the new rv side plug and the cord is so much easier to plug in and much easier to handle in the cold.

  • Recommended Smart Plug 50amp RV Power Cord to Work w/a 30 amp 240V Generator
    Hey Pat, congrats on your new trailer. Since you're converting over to a 50 Amp SmartPlug RV Power Inlet like item # SM56FR, you can use the SmartPlug Marine Power Cord Adapter - 50 Amp Female to 30 Amp Male Twist Lock Connector item # SM43VR This 4' adapter lets you connect your 50-amp SmartPlug cord to a 30-amp twist lock. It is only rated to 125 volts though. We also have the SmartPlug RV Power Cord - 50 Amp - 30' item # SM86FR and the Angled RV Power Cord - 50 Amp - 30' item # SM54SB....

  • Does SmartPlug Make 50' 50 Amp Angled RV Power Cord
    Hey Dameion! SmartPlug only offers the 30' Angled RV Power Cord # SM54SB at this time. The only option to get to 50' would be to add in an extra cord to extend it like # A10-5025E. What kind of trailer do you have?

  • Looking for 90 Degree Smartplug RV Power Cord
    Hey Michael, while we don't have a replacement plug that is 90 degree we have a 30 foot long 50 amp power cord that has a 90 degree connector on both sides with the part # SM54SB if that's something you'd be interested in.

  • Availability of SmartPlug Angled Adapter
    Hi David; I'm not aware of SmartPlug working on an adapter, and it doesn't sound like one is coming in the near future. Right now the only option would be to replace your existing cable with the SmartPlug Angled RV Power Cord # SM54SB. You could keep the other as a spare or try to sell it to recoup some of the cost. What kind of trailer do you have?

  • 90 Degree Angled SmartPlug Connector For Inlet
    Hi George, That’s a great question. The SmartPlug RV power inlet kits only come with straight connectors there isn’t a 90 degree connector sold separately by itself. The only 50 amp 90 degree angled cord SmartPlug currently offers is part # SM54SB. If you wanted to go that route, you could pair it with the SmartPlug 50 Amp Power Inlet in black, part # SM56FR. If your main concern is stress on the inlet, SmartPlug systems are actually designed to reduce that. Unlike traditional twist-lock...
