Buying guide

When buying an RV extension cord, it is important to do enough research in advance before settling on the right specific product to purchase. The right RV extension cords can be a smart investment to make for your vehicle. Some of the factors you need to consider before choosing your best fit include:

Power ratings

You need to take note of your RV’s power level. Some RVs use up to 50 amp power. The thickness of the wires inside an extension cord and its length is normally directly related to the amount of power that the cord can carry. Longer extension cords require thicker conductive copper wires to avoid overloading it. Ensure to get the right extension cord commensurate to your power supply. Safety hazards arise where extension cords overheat and melt, possibly causing a fire.


Get your measurements right so that you can get the extension cord that is suitable for your needs. This is because the longer the extension cord, the more capacity you will need to carry the electric charge and vice versa. Unnecessarily long extension cords tend to waste energy thus increasing your expenses.

Safety standards

Ensure to do ample research of the product to confirm that it is one that is approved and adheres to the set safety standards. Since electric products are very sensitive, go for high-quality products that are ranked by independent consumer safety companies. Extension cords that are bright in color tend to be more visible thus reducing possible cases of people tripping over them and causing injuries.


A flexible extension cord is easier to maneuver and would lay flat on the ground thus reducing chances of accidents. A flexible cord also is easy to stretch at the time of fixing it for use as well as folding it after use for storage.


An extension cord whose manufacturer has issued a warranty against gives some sort of assurance that the product would be repaired or replaced altogether if it is found to be in default.


Tips for using RV extension cords

  • To reduce the possibility of electric shock, always use an extension cord with a ground wire.
  • Keep a few lengths of extension cords in your RV so that you can use the shortest cord necessary to minimize risk factors.
  • Take note of the AWG rating and length of your extension cord as it affects the amp rating.
  • Extension cords should be used temporarily and not permanently. Thus use them when it is only necessary.
  • To make things safer, avoid joining several extension cords to lengthen the range.
  • Inspect your extension cord regularly for damages. If any, do not use the extension cord as it may prove dangerous.
  • Always unplug extension cords when they are not in use.
  • When disconnecting from the outlet, always pull the plug and not the cord.
  • Keep extension cords away from places with water or snow.
