For example, there are RV power cords that come in a standard size which is 25 feet. But if you need a longer RV power cord, there are 40 feet and 50 feet variations. Or perhaps you want a shorter one, there are RV power cords available with a length of one foot to 5 feet. These shorter cables are best to use as connectors or plug adapters between your extension cords in case you need them.
As for Amp rating, the basic RV power cords come with a 15 amp rating. This is the minimum amp rating that you’ll need for your camper. But should you need an RV power cord with a higher current-carrying capacity, you can find them also in 20, 30, 40, and 50 amps.
RV power cords are able available in different voltage ranges from 125 to 250 volts. Of course, you have to choose which one will suit your voltage requirement in your camper.

What to Look for When Buying an RV Power Cord
RV power cables come in different variations. And as an RV owner, you would know the specific purposes you need them for inside your camper. Before buying one or more of these, take a moment to think about these factors so that you’ll get the best RV power cords.
It is important to get an RV power cord with the right length. You should consider the distance of the RV appliances that you’re going to use from your power source. Are they near or far from your power source? Would you need a short or long cable? Recreational vehicles come in different sizes and your appliances can be near or far from the power supply.
RV power cords come in different lengths. The standard is 25 feet but there are power cables available in shorter or longer sizes.
One would probably say just get the longest cable length to be safe. This way you won’t be restricted to how close you need to be to the power source when you’re at camp.
But you have to understand that the longer the power cord, the bulkier and heavier it gets. As expected, cords with a length of 40 or 50 feet will weigh more and since they are bulkier, you would need a bigger storage space for them. The one foot and 5 feet cables are lighter to carry and easier to store.
Another important thing to remember here is the amount of voltage lost the longer the cord is. There is voltage drop because of the resistance in the cord wires.
The best RV power cord is the right length for your electrical needs inside your rig.
RV power cords can vary in capacity. This means you have to look for the RV power cord that can meet your power requirements such as the wire gauge, amp rating, the power supply it can be connected to, and which appliances and devices they can handle.
For example, you have a 120V RV power cord with a gauge of 12 AWG. You’ll know that the wires are thick and this is intended for use with standard 120V outlets.
You will also find RV power cords with lower amp rating such as 10 amps. This means you can only use them for light electrical appliances such as your TV or computer. But if you will use your power cable for your heating appliances and tools, you should get one with a higher amp rating at 15 amps.
Getting the best RV power cord will depend on your purpose for using the power cord. You can choose one that would meet your power needs. It is also advisable to check the number of amps required by your rig before buying an RV power cord so that you can be sure that it is suitable for your camper.
You don’t want to buy an RV power cord that’s easily damaged. It can compromise your safety and once broken, you need to buy a replacement and that means added expenses.
Make sure you check the power cable’s construction and design. It is best to get a heavy duty power cord that’s made with full copper wire because it is more durable and has a higher power capacity. It also won’t heat up which makes it safer to use.
Look for an RV power cord with an ergonomic design to make plugging and unplugging easier for you to use it. It makes disconnection so much easier. We all know how snugly the plug ends connect to the power cord and you would need to exert quite an effort just to disconnect them. An RV power cord with an ergonomic design has a grip handle so that you can hold onto it while pulling the plugs.
It’s best to read the customer reviews regarding their feedback on the durability of the product. Make sure that you buy from trusted manufacturers and selling sites so that you can get the best RV power cord.
RV power cords are available at different price points. As what we always say, set a reasonable budget for your purchase so that you can choose a power cord with a price that fits your budget.
We say reasonable because you should also consider its specifications and features. For example, longer power cords will cost you more than shorter ones so you should be prepared to spend more if you need a longer cable.
You should also check the customer reviews so that you will know if it offers value for your money. Is the price worth it for its quality and capacity? Their feedback is valuable in this aspect.

Frequently Asked Questions
What plug does an RV use?
RVs usually use a large three-pronged 120V plug that’s heavy duty with 30 Amp rating. Most RV parks and campgrounds with electrical hookups have a 30 Amp outlet where you can plug your RV power cord into.
What gauge extension cord do I need for an RV?
The gauge refers to the thickness of the wire in your power cord. The wire’s diameter affects its current-carrying capacity and how much the wires heat up when in use.
You will know the gauge rating of an RV power cord when you see the value of the American Wire Gauge (AWG) number. For example, there are power cords with 6 AWG, 8 AWG, 10 AWG, 12 AWG, 14 AWG, 16 AWG, or 18 AWG ratings. The smaller the AWG rating the thicker the wires.
For RV owners wondering what gauge to get, it would depend on their power needs. If you get an RV power cord with a gauge that’s lower than your electrical requirements, it won’t be able to sustain the current which will cause the cord to heat up and burn. This is dangerous as it could lead to fire. This is why it is important that you get an RV power cord with the proper gauge rating.
Here’s a guide that you can use to help you determine the gauge rating for your RV.
- 15 amps (max current) = 14 wire gauge
- 20 amps (max current) = 12 wire gauge
- 30 amps (max current) = 10 wire gauge
- 40 amps (max current) = 8 wire gauge
- 50 amps (max current) = 6 wire gauge
Take note that we are talking about the maximum current here. If you go beyond this, overheating may occur.
You also have to take into account your power source when you’re parked at RV parks and campgrounds. Their electrical current range should be compatible with your rig before you plug your RV power cables into them or else your cord will heat up and burn.
How to install RV power cords?
RV owners need to know that they shouldn’t just plug their RV power cord into the shore power without checking the available outlet. You need to make sure that the outlet’s power is suitable with your rig.
You can use a multimeter to test the voltage. You just need to insert a probe in each slot to be able to determine the line voltage measurement. The reading will show if it is 110V or 120V. Remember if the voltage is too low or too high for what you need, it will damage your appliances.
Once the test shows that the power in the electrical outlet is compatible with your rig and power cord, then you can install or plug your RV power cord.
What are some care and maintenance tips for RV power cords?
Taking care of your RV power cords is simple. You just make sure there are no dirt, mud, and other unwanted particles on both ends of the cable. You can wipe them off so that they won’t cause any damage to the PVC sheath of your RV power cord.
Check also if there are damages in the RV power cord before using them. You can buy replacement parts for the cord itself, or damaged plug ends and receptacle ends.
To prevent damages, make sure that you store your RV power cords properly. Roll them up nicely and put them inside a storage box. Some RV power cord models come with coils to help with ease of storage.
How long can a 30/50 Amp RV cord be?
As mentioned above, RV power cables come in different lengths. Usually 25 feet to 30 feet is enough to power your appliances inside the rig. But there are longer cords too reaching all the way to 50 feet.
Take note however that a longer RV power cord means more voltage is lost and less power is transmitted from your power source to your appliances.
Is it bad to leave your RV plugged in all the time?
Yes, it is bad practice to leave your RV plugged in all the time. You should know that as you’re plugged in to a power source – be it an electrical hookup, generator, or solar system, the batteries of your RV are also charging.
If you keep your RV plugged in all the time, your wet cell batteries’ water level will drain faster. This will deplete the electrolyte levels in your battery cells.
Can I plug my RV into 220v?
The electrical system of recreational vehicles has been designed to run on 120V AC. If you plug it into a 220V, different issues can arise- the AC mechanical drive may fail to start, it will take up more current than it has designed for, and it could lead to a burn out.
What size wire is in a 30 amp RV cord?
A 30 amp RV power cord will have a 10 gauge wire in it. You’ll need this info in case you need to wire a 30 amp RV outlet.
Can I plug my RV into an extension cord?
Yes you can but you need to use special adaptors for this. You can’t just plug your 30 amp RV into an extension cord. At the very least you need a 30amp hookup to be able to supply you with enough power.
Take note that normal outlets in our homes do not have enough power supply for your RV. If you want to hookup your RV into your home’s electrical system, look for a 30/50 amp hookup. This is an adaptor that you can plug into your 3-prong wall outlet. Then you can now plug your RV into an extension cord and into the adaptor so that you can charge your RV.
It is recommended that you use a short extension cord for this. Because if you use a longer cable, there is a higher probability of overheating. And before you plug in the extension cord to your RV, make sure all your electrical appliances inside your rig are turned off.
Can I plug my RV into a 110 outlet?
As mentioned above, yes you can pug your RV into a 110 outlet in your home’s electrical system. But you would need to use an adaptor so that you can plug your RV into your 3-prong wall outlet at home.
While it is possible to plug your RV into a 110 outlet, it is not recommended that you do so for an extended amount of time. Keep it short to avoid overheating.
Is a 50 amp RV plug 110 or 220?
A 50 amp RV plug is 220V that has 4prongs on the male and female plugs. Among these, 2 are 110V to neutral or ground and the voltage between them is 220V. The other prong is the neutral and the round prong is the ground.
Take note that you shouldn’t connect your RV directly into a 220V service outlet.
