Modern RVers from novices to veterans know that the charge level of RV battery banks affects the performance of a wide range of amenities onboard. If camper owners let the batteries deplete, they would lose the ability to take advantage of their amenities and that leads to low comfort levels. 

Nowadays, RVing enthusiasts may use many power sources to charge battery banks but usually, an RV power cord is necessary. Without a solid cord to move electricity from power sources to batteries, RVers would have a hard time restoring the charge level of battery banks. Therefore, unless you want to run your batteries to depletion, you need to search the market for a high-quality power cord before heading out. By keeping a good cord on your rig, you could utilize power sources on the road to keep batteries charged throughout your travel. 

RV Power Cord Basics

What is an RV power cord?

In layman’s terms, a RV power cord is a heavy-duty power cord that links vehicles to their power sources: generators, charging pedestal, etc. After RVers set up the connection, power cords should let electricity flow from the power sources to batteries through them. Compared to their residential counterparts, power cords for RV tend to be thick which enables them to handle high loads. In addition to that, a number of RV power cords incorporate integral lock rings that provide added security during connection. 

Benefits of RV power & extension cords

  • Charge: Assuming that you install your RV power cords properly, they would guarantee a constant flow of electricity from power sources to your battery bank. That means it’s easy to bring the battery back to full charge for the next part of the trip. 
  • Schedule: With RV power cords by your side, you don’t have to wait for long to fully charge the battery bank of your rig. The faster you restore the level of charge of the batteries, the earlier you could head back to the road. Hence, staying on schedule is a walk in the park. 
  • Adaptability: Capable of working in a multitude of conditions, RV power cords permit you to charge the battery of your RV regardless of the weather. That is a big plus if you spend most of your time in the outdoors. 
  • Safety:  Usually, owing to the exterior casing, modern power cords for RV resist heat, cold, moisture and so on well. Besides that, such power cords also integrate a couple of features to minimize the odds of failures throughout the charging. As a result, you should be able to charge batteries via RV power cords with a high level of safety. 

Types of RV power cords

At a glance, the market contains numerous models but it’s possible to split RV power cords nowadays into three types: 15 Amp, 30 Amp and 50 Amp. 

  • 15 Amp Power Cords: Designed for basic application, 15 Amp power cords resemble residential models with two thin vertical prongs (hot and cold) and one round prong (ground). Due to the low load limit, cords of the type could only support the charging of batteries on small vehicles. At 1,800W, the amount of power that these cords deliver is barely acceptable. In the case that your rig lacks power-hungry appliances like air conditioners, 15 Amp power cords would match it well. 
  • 30 Amp Power Cords: For mid-size travel trailers with medium charging requirements, 15 Amp power cords prove to be excellent choices. In use, the majority of models of the type have an easy time charging batteries of vehicles with a single A/C in the interior. On average, such power cords should bring 3,600W to the RV battery bank at any one time. About prongs, 15 Amp power cords pack three prongs but the prongs sit at an angle instead of parallel/above-under.  
  • 50 Amp Power Cords: Being the biggest models, 50 Amp power cords have the best load limit on the market which makes them well-suited for high-end charging. The four prongs (two hot, one neutral and one ground) of models of the type would give batteries a total of 12,000W in the course of charging. Interestingly, it’s worth pointing out that 50 Amp power cords actually supply power in separate feeds. That is why RVers could use power cords with the 50 Amp rating to power independent legs of services at the same time.

Critical RV Power Cord Considerations

Regarding camper power cords, different RVers tend to look for different things but to make a wise investment, you must memorize the following. 


All in all, the load limit of a travel trailer power cord dictates the amount of electricity it’s able to handle. As a result, while assessing models available for purchase, it’s strongly recommended that you keep load in mind. In the case that you don’t use a lot of electricity on the road, you may settle for 15 Amp and 30 Amp power cords. However, if you own a rig with high power consumption, you should keep an eye out for 50 Amp models. 


For many reasons, it’s sometimes impossible to park vehicles close to external power sources to recharge batteries. Because of that, to get the most out of your power cord for RV, you have to give length some thought. The industry standard is 25 feet which is sufficient for a lot of situations but it’s noteworthy that other lengths exist. Usually, by taking a look at the owner’s manual, you could determine the length of a model with relative ease. 


Overall, it’s ill-advised to treat power cords roughly but you don’t want to pick up flimsy models that fail shortly after purchase. Unless you have the money to spend on regular cord replacement, it’s suggested that you pay special attention to durability. One way to tell whether a model would hold as time passes by is to check out its materials. Models made from high-quality materials last for years to come and that is advantageous in full-time RVing.

Space is a luxury on RV, thus, it’s imperative to take storage into account to select appropriate camper electrical cords. The last thing you need is an oversized cord that occupies a huge chunk of the storage space of your rig. For good measure, prior to committing to a purchase, you should inspect the dimensions of the cord you like via the owner’s manual. Additionally, it’s a good idea to read a couple of reviews of customers to see what they say about the ease of storing particular models. 


  • $40 – $80: Being entry-level models, power cords in the range perform well in use despite the fact that they don’t have a lot of features. Furthermore, the affordability of models with prices between $40 and $80 earn a shower of praise from cost-conscious camper owners. 
  • $80 – $160: Able to satisfy the majority of charging demands without costing a fortune, power cords in the range provide great values. If you seek solid cords but your wallet is kind of tight, you should stick to modes that cost from $80 – $160. 
  • Above $160: By making good use of innovations in technologies, materials and so on, power cords in the range give a good account of themselves in various conditions. Needless to say, those that place quality above all else hold models with prices exceeding $160 in high esteem. 

How To (And Why) Replace An RV Power Cord

Generally speaking, no matter how modern, everything on travel trailer breaks down one day and the RV power cable is not an exception. The moment the cord gives out, RVing enthusiasts would experience multiple headaches from slow charging to disruptions in the operation of appliances. 

Hence, RVers including novices as well as veterans regard the knowledge of cord replacement as essential in RVing. Assuming that the replacement of cord proceeds smoothly, RVers could put an end to fluctuations in the flow of electricity. Of course, you always have the option of leaving the replacement of cord to professionals if you don’t have confidence. Still, if you like to save money, feel free to replace the malfunctioning cord on your own. 

  • For damaged plug: Disconnect power, cut away the plug and expose the wires. Next, connect the wires to a replacement plug that uses the same design as the old one. After you manage the wires, hook up the plug to an external power source to see how it performs. 
  • For damaged cord: For cords with minor damages on the exterior, electrical tapes should be adequate. Nonetheless, if the cords sustain extensive damages, it’s best to buy new ones.

FAQs About RV Power & Extension Cords

1. Does power cord come with RV?

Upon purchase, most rigs arrive alongside a power cord to connect to external power sources. Depending on the RV, the rating of the stock cord varies between 15, 30 and 50 Amp. Normally, the owner’s manual contains details regarding the power cord from location to specs. If you cannot locate a cord on your vehicle, you have to equip it with one at the earliest opportunity. 

2. Can I use a regular extension cord for my RV?

For your safety, you must refrain from using regular extension cords to charge the battery bank of your rig. Non-RV cords cannot handle the kind of loads that RVing desires so it won’t take long for them to overheat. Obviously, when extension cords overheat, all sorts of issues would occur which place the vehicle as well as the people at risk. Thus, it’s imperative that you stick to purpose-designed models while buying extension cord for your RV. 

3. What size extension cord do I need for my RV?

The gauge of extension cords depends on the load that passes through them to the batteries of vehicles. For 15 Amp and 30 Amp power cords, the minimum size for extension cords is 10 gauge. In the case that you use 50 Amp power cords, it’s widely advised that you prioritize 6/3 + 8/1 and 6/4 gauge extension cords. 

4. Can I adapt my RV power cord up?

It’s possible to adapt power cords to external power sources with higher ampere rating in times of need. To do so, you have to get your hands on an adapter to match the rating of your power cord to that of the sources.

5. Do I need a dogbone/adapter for every situation?

Today’s camping locations usually have power sources of variable ratings but for good measure, you should prepare at least two adapters. For instance, if your RV carries a 30 Amp power cord, it’s a good idea to include 30 Amp-to-15 Amp and 30 Amp-to-50 Amp adapters to your inventory.

Interestingly, if the rating of the power cord of your RV is 50 Amp, you could combine adapters when a need arises. By combining a 50 Amp-to-30 Amp adapter and a 30 Amp-to-15 Amp one, you should be able to connect your 50 Amp cord to 30 Amp power sources.

6. Can you use an extension cord for your RV power cord?

You could extend the reach of your RV power cord using extension cords but you have to use models rated for RV. If you use non-RV extension cords, it’s only a matter of time before troubles surface during the charging process. 

7. Is a 50 Amp RV plug 110 or 220?

Presently, the majority of camper run on 120V so the power cords that accompany them, including 50 Amp models, have a voltage rating of 120/240V. In most of the cases, you could plug your RV cords into 120V power sources but remember to stay away from 220V ones.

Plugging modern cords for RV into 220V power sources would cause extensive damages to electronics onboard. Fortunately, few camping locations nowadays carry 220V power sources so the odds of a mix-up tend to be low.
