Best 30 Amp RV Extension Cords & Adapters Reviewed 2021

What Kind Of RV Extension Cord Do I Need?

I’ve you’ve stayed at a couple of RV parks you’ve probably noticed that the location of the hookups and varies a lot. Many RV’s have power cables in different spots and you never know where the outlets are going to be.

Our travel trailer had the outlet in the back, now our Class C RV has the main power cable in the front. Most of the time we can make it work but there have been a few campgrounds we’ve stayed at where a 30 amp RV extension cord would have really helped us out.

They’re also really nice if your generator has a 30 amp outlet and you want it to be as far away from your RV as possible to reduce noise.

When choosing a 30 amp extension cord for your camper one big thing to look at is the kind of plug or outlet that’s on your RV.

There are two main kinds of 30 amp outlets you find on a camper. There’s the standard TT-30P RV plug with 3 straight prongs or there’s the common twist lock style that requires a NEMA L5-30R plug.

The first 4 RV extension cords on the list are the standard TT-30P straight 3 prongs and the last two are for campers with a twist lock outlet. Make sure you check what kind your RV uses before purchasing.

If you have a short 30 amp twist lock cable for your camper you can also get a standard 3 prong 30 amp RV extension cord and connect it to the end of the power cable you already have.

But if you only want one cable to run from your RV to the outlet you will want to get one with a twist lock end.

In this review, I’ll go through some of the best 30 amp RV extension cords on the market today.

If you’re looking for a 50 amp RV power cord you can go to this review to check out the best ones.

I’ll also list some useful RV plug adapters that can be useful to have in your arsenal of RV gear.

Best 30 Amp RV Extension Cords Reviewed

1. Camco Power Grip 30 Amp Extension Cord

Camco (55191) 25' PowerGrip Heavy-Duty Outdoor 30-Amp Extension Cord for RV and Auto | Allows for Additional Length to Reach Distant Power Outlets | Built to Last

Check Price at Amazon

Camco makes some of the best RV gear on the market today and its 30 amp RV extension cord is no exception.

It’s made with heavy duty 10 gauge copper wire with a flame retardant and heat resistant PVC coating. The cable is flexible but durable.

The male end is the standard 3 prongs 30 amp for RV outlets and the female end uses the same style. The plugs are made to sit at 90 degrees which helps take the pressure off of the prongs and fits RV style outlets better.

If your camper has a twist lock outlet this may not be the RV cord for you but for most campers, this is what you want.

Each end uses Camco’s power grip design with large handles you can use to safely and more easily pull the plugs apart.

If 25 feet isn’t quite enough length Camco also makes a 50 foot version of this 30 amp RV extension cord (click to view on Amazon) that has all the same specs as the 25 foot one. It just weighs twice as much.

See Also: The Surprising Differences Between 30A & 50A RVs

The 25 foot Camco RV power cord weighs almost 8 lbs which means the 50 foot version weighs around 16 lbs. Both lengths are rated to carry up to 125 volts/3750 watts.

The Camco Power Grip 30 Amp Extension Cord is one of the best options out there if 25 feet is going to be enough distance and if your RV doesn’t have a twist-lock outlet.

It’s durable, uses the best materials for carrying high voltages, and it will get your RV the power it needs for the kind of camping you want to do.

The only thing that might make the Camco not right for you is the size of the plugs. If you need to fit the cable through a small hole in your RV the grips might make it difficult.

PROS

  • Uses Copper Wire
  • Handles On Plugs
  • Heat Resistant PVC Cover
  • 90 Degree Plug Heads
  • 25 & 50 Foot Length Options

CONS

  • No Carry Strap
  • No LED Indicator

2. Coleman Cable Road Power 30 Amp RV Cord

Road Power 95707508 10/3 30' STW 30-Amp RV Extension Cord, Heavy Duty, Waterproof Cord, Suitable for Mobile Homes and Recreational Areas, UL & cUL Listed, TT-30 plug, Built to Last , Black

Check Price at Amazon

The Road Power 30 Amp RV cord by Coleman Cable is one of the more simple RV extension cords you can get with a couple of good features like an LED power indicator and a pure copper core.

Like the other 30 amp RV cords in this review, the Road Power can transfer 125 volts and 3750 amps.

There’s only one length option, 30 feet. It weighs 8.35 lbs.

The 10 gauge copper wire is covered in a weather resistant plastic coating that is durable and made to sit outside.

The one thing that isn’t quite as durable and water resistant on this RV extension cord is the ends.

There are no handles on the male or female plugs but there is an LED power indicator on the female end. Having no handles on the plugs could be a pro if you need to feed the cord into your camper but it does make it harder to disconnect them.

This RV cord uses the standard straight prong TT-30P RV plug style which means it won’t work with RV’s that use twist lock outlets.

The prongs stick out from the plugs at 90 degrees which is best for RV use.

The main con to this RV power cord is the female plug end. It uses a different kind of design where the plastic forms around the prongs in a more fitted way. This causes a gap in certain plugs which could potentially allow water inside.

This is mostly only an issue if you have the RV extension cord connected to another one so the connection is exposed to the elements.

You can solve this problem by making sure the female end of the Road Power cable is plugged into the male RV plug inside the RV or put it inside a waterproof electrical box.

The Coleman Cable Road Power 30 Amp RV Cord is a great value and a good length that should be enough for most RVers.

If you need a 30 amp RV extension cord that has small plugs to fit through holes this is a great option but make sure any connections are either inside a waterproof box or inside your RV.

PROS

  • LED Power Indicator
  • 90 Degree Plug Heads
  • Uses Copper Wire
  • Included Cable Strap

CONS

  • Only 1 Length Option
  • Female End Not Waterproof

3. Parkworld RV 30A Extension Cord

Parkworld RV 30A Extension Cord NEMA TT-30 with Handle, Camper 30amp TT-30P to TT-30R (50 Feet)

Check Price at Amazon

The Parkworld 30 amp RV extension cord is the best of both worlds. It has small plug heads but also some handles you can use to grip the plugs when pulling them apart.

There are a lot of length options: 25, 36, 50, 75, and even 100 feet.

The 100 foot option is pretty rare when it comes to heavy duty RV extension cords since they need to be so huge to be able to transfer power that far.

The Parkworld 100 foot 30 amp RV power cord works well and is better than connecting two 50 foot power cords.

On all the lengths you get a 10 gauge copper core and a heavy duty PVC outer cover that is durable and heat resistant. They all use the standard straight blade 30 amp RV connection also known as TT-30P.

These will not attach directly to twist lock RVs without an adapter.

The RV cords up to 50 feet are rated for 3,750 watts and 125 volts.

The 100 foot cable (click to view on Amazon) is rated for 7,500 watts to help cover the distance.

The 50 foot version weighs around 14 lbs while the 100 foot weighs twice as much at 28 lbs.

Both the male and the female plug ends have LED light indicators to show that the RV cord has power.

The Parkworld RV 30A Extension Cord is a fantastic option for those who need a 30 amp RV power cord with smaller heads than the Camco, lights that indicate power, and handles to make disconnecting easier.

The plug style isn’t quite as heavy duty as the Camco but so long as your main RV plug and the 30 amp plug are covered it shouldn’t be a problem.

PROS

  • LED Power Indicator
  • 90 Degree Plug Heads
  • Uses Copper Wire
  • Handles On Plugs
  • Multiple Length Options

CONS

  • No Included Cable Strap
  • Plugs Could Be More Heavy Duty

4. RVGUARD 30 Amp RV Power Extension Cord

RVGUARD 30 Amp 30 Feet RV Power Extension Cord, Heavy Duty STW 10AWG 3 Wire with LED Power Indicator and Cord Organizer, 30 Amp Male to 30 Amp Female Standard Plug, Green, ETL Listed

Check Price at Amazon

This is the last TT-30P 30 amp RV extension cord in this review.

The RV Guard has a couple of length options to choose from. 15, 25, 30, or 50 feet.

The inner core is made with 10 gauge copper wire much like the others in this list. The wires are covered with heat-resistant insulation and a durable PVC sleeve.

Even though the plugs are made with solid colored plastic there is still an LED light indicator on the female plug side down near the base.

As I mentioned both ends use the standard 30 amp RV plug style with three straight blades. They won’t be able to directly connect to a twist lock outlet without an adapter.

The plugs are a nice medium size with grip handles molded into the back.

A plastic cable organizer is included. You can use it to hold everything together and even hang this heavy duty 30 amp extension cord on a wall.

There’s also a plastic storage bag thrown in for storing in your RV.

The 30 foot RV power cord which is the length I’ve linked to above weighs a little over 9 lbs.

The maximum watts is 3,750 and voltage rating is 125.

The RVGUARD 30 Amp RV Power Extension Cord is another fantastic option with a couple of lengths to choose from.

PROS

  • LED Power Indicator
  • 90 Degree Plug Heads
  • Uses Copper Wire
  • Handles On Plugs
  • Multiple Length Options
  • Cable Strap & Bag Included

CONS

  • PVC Sleeve Not As Durable As Others

5. Kohree Locking 30 Amp RV Extension Cord

Kohree 30 Amp RV Power Extension Cord 50 ft with Grid Handle Heavy Duty, 30M/30F 90 Degree Locking Adapter, LED Indicator & 15M/30F Power Adapter(1875 W), 125V, 3750W, ETL Listed STW Wire

Check Price at Amazon

The next 30 amp RV extension cords are for RVs with the NEMA L5-30R or twist lock outlets on their campers.

When using a long extension cord you want to try and have as few cable connections and adapters as possible. That’s why if your camper has a 30 amp twist lock outlet you want to try and get an extension cord with a female twist lock plug.

The Kohree has a twist lock on the female side with a standard TT-30P male plug on the other to connect to standard 30 amp RV outlets.

The male RV plug has a built in grip handle on the back and the female side even has an LED light power indicator.

One nice thing about RV twist lock connections is they have the waterproofing ring that screws on around the connection so it’s safe to have connecting outside of the RV.

The two length options are 25 or 50 feet long.

The 10 gauge inner wire is made with 100% copper and each length is rated for 3,750 watts and 125 volts.

The outer sleeve is made with durable heat resistant PVC that can handle weather and being outdoors.

Included with purchase is a plastic storage strap and a small 15A to 30A adapter for plugging into regular home outlets.

The Kohree Locking 30 Amp RV Extension Cord is one of the best options out there for RV’s that have a twist lock outlet on the outside.

The twist lock is pretty common especially on travel trailers and 5th-wheels and this may be the best option for that reason.

PROS

  • LED Power Indicator
  • 90 Degree Plug Heads
  • Uses Copper Wire
  • Handles On Plugs
  • Multiple Length Options
  • Cable Strap Included

CONS

  • For L5-30R (Twist Lock) Only

6. RVMATE 30 Amp RV Lockable Power Extension Cord

RVMATE 30 Amp 50 Feet RV Lockable Power Extension Cord, Easy Plug in Handle, TT-30P to L5-30R with LED Indicator, 10 AWG, ETL Listed

Check Price at Amazon

Finally in our best 30 amp RV extension cord review, we have another awesome RV power cord with a female end that’s for L5-30R twist lock campers and a male end for standard TT-30 RV plugs.

The RV Mate is very similar to the Kohree reviewed above.

It has an LED light indicator on the female end, uses 10 gauge copper wire, a durable PVC sleeve, and there’s even a grip handle on the back of the male plug.

Like all twist lock RV plugs the female connection side is waterproof and uses a ring to screw onto your camper for a solid connection.

There are two length options, 30 or 50 feet.

The 30 foot cable weighs over 9 lbs and the 50 foot cable weighs 15 lbs.

Both sizes come with a plastic strap used for storage and a plastic storage bag.

The RV power cord is rated for 3,750 watts and 125 volts.

The RVMATE 30 Amp RV Lockable Power Extension Cord is another great option for campers that use the twist lock.

I’ve mentioned this before but you want to limit the number of adapters and connections when using a long RV extension cord which means getting an extension cord that already has the correct configuration is the best way to go.

If you need a 30 or 50 foot 30 amp RV extension cord with an L5-30R female end and a TT-30 male end this is a fantastic choice.

PROS

  • LED Power Indicator
  • 90 Degree Plug Heads
  • Uses Copper Wire
  • Handles On Plugs
  • Multiple Length Options
  • Cable Strap Included

CONS

  • For L5-30R (Twist Lock) Only

Best 30 Amp RV Extension Cord Conclusion

Many of the 30 amp RV extension cords in this review are made with similar materials. They all use copper 10 gauge wire and have heavy duty PVC sleeves.

When it comes down to choosing the right one for you I would look mostly at the length options and the plug sizes.

If you need to be able to fit the RV power cord through a small pipe or hole you may want to go with one of the options that has a smaller plug.

If your connections are going to be exposed to the elements (not recommended) you may want to go with the most heavy duty plug head in the review.

You also need to check what style of female plug your RV uses.

Some campers have a long cable with a TT-30 male plug that’s wired directly to the converter box. For this kind of 30 amp RV you just need a regular TT-30 RV female to TT-30 RV male. The first 4 RV power cords in this review are that kind.

If your RV has a twist lock outlet on the outside of it you will need a 30 amp RV extension cord with a L5-30R female end and a TT-30 male end.

Make sure you know what kind of plug ends you need before purchasing.

Best 30 Amp RV Plug Adapters

For RVs With TT-30P RV Plugs

Camco 30 Amp to 15 Amp Dogbone RV Adapter

Camco (55165) Heavy Duty RV Dogbone Electrical Adapter with Innovative 180 Degree Bend Design and Easy PowerGrip Handle - 15 Amp Male to 30 Amp Female, 12' , Black

Check Price at Amazon

A good 30 amp to 15 amp RV plug adapter is a must have for any RVer.

Even though you won’t be able to use the full 30 amp service in your camper you will still be able to run a few of the necessities and keep your RV batteries charged up.

Camco makes some of the best RVing gear on the market and its adapters are no different.

If your camper has a standard straight blade TT-30P 30 amp connection this is the adapter you want to have with you at all times.

The adapter is dogbone style which means it’s two plugs on a short cable. The cable is made with 10 gauge copper wire with a durable PVC coating.

Even though this RV plug adapter uses 10 gauge wire it’s only capable of transferring up to 1,875 watts of power since the power source is only 15 amp.

The 30 amp female end has a large grip handle to make pulling apart connections easy. Each end uses the low stress 90 degree design that works super well with RVs and RV outlets

If you have a 30 amp RV extension cord with a TT-30P or straight blade 30 amp male end then this is the kind of RV plug adapter you want.

You can use the extension cable to reach the 15 amp outlet and then connect this dogbone to fit the smaller power source.


Manshan 50A To 30A Dogbone RV Adapter

50 Amp to 30 Amp RV Adapter, Heavy Duty, Durable and Safer Plug with an Easier Grip and LED Indicator Light

Check Price at Amazon

You may be wondering why you would need a 50 amp to 30 amp RV plug adapter when a 30 amp outlet is probably more common than a 50 amp one.

I recommend having one because even in newer RV parks sometimes the 30 amp receptacle can be worn and may not be as stable as the 50 amp one.

If you are staying in a smaller campground or park they may have only installed 50 amp since they can power every kind of camper with the right adapter.

It’s not a huge investment and it’s just a good thing to have if you travel in an RV a lot.

See Also: Will A 50A RV Surge Protector Work In A 30A Outlet?

The Manshan dogbone RV plug adapter has a standard 4 prong 5 amp male side and a TT-30P standard RV 30 amp female side.

If you have a long 30 amp RV extension cord you can use this at the end of it to supply your 30 amp RV using a 50 amp outlet.

The RV adapter can supply the full 3,750 watts needed for full 30 amp power and your RV will work as if you are plugged into a 30 amp outlet.

It may be rare when you need something like this but it’s a good small gadget to add to your RV gear.


For RVs With L5-30R Twist Lock RV Plugs

Camco 30 Amp Twist Lock Dogbone RV Adapter

Camco 55512 PowerGrip 18' 30 AMP Male Standard/30 AMP Female Locking Adapter

Check Price at Amazon

If you have a 30 amp RV extension cord with TT-30P female and male plugs and you just found out your new camper has a twist lock outlet this is the RV plug adapter you will need.

Even though it’s best to try and use as few adapters and connections as possible when plugging in your RV to a power source sometimes you have to do what it takes to get things to work.

If for whatever reason you need to turn a L5-30R twist lock style 30 amp plug into a standard TT-30P plug, this is the dogbone adapter to get.

It uses 10 gauge copper wire, is rated for the full 3,750 watts and 125 volts, and has a grip handle on the male plug.
