Factors to Consider Before Purchasing the Best 30 Amp RV Extension Cord

1. Length and Thickness

The first and the most important to consider is the length of your RV's power cord. Reasonably, it is vital to be equipped with the longest extension cord to avoid inconveniences while camping. On the technical part, the length of an RV cord affects the load capacity and the power output.

Besides a cord's length, you should also check the thickness of your select extension cable. Ideally, the wire gauge thickness affects the amount of current that a wire can carry. Subsequently, within the thickness factor, one will be able to determine if a wire heats, and if so, to what extent. Accordingly, you should get a cord with adequate thickness to allow for adequate power carriage without or less heating up.

2. Construction

Once you've identified the appropriate length and thickness of your extension wire, it is also important to check the construction details of the same. Construction mainly involves evaluating the materials used in making a power extension cord. It is always best to buy 100% copper wires brands because they don't spoil quickly and don't heat up easily.

Apart from the functional capacity of a 30-amp power cable, you should also be mindful of its storage flexibility and durability. For example, after disconnecting your extension cord from a generator or a power source using a power grip, you will need to store it without the fear of damage. Consequently, we recommend investing in brands that offer flexible cables. If possible, you can also invest in a versatile construction such as a Y-adapter cord for flexible connections.

3. Price

After you have identified the appropriate functional properties of your extension cord, the next consideration will be the price. Since there are various 30 amp RV extension cords, you will face the dilemma of cost versus quality. Luckily, the price of RV power cords often reflects the quality of materials used in the construction and their thickness. Notably, the higher the price, the better the quality, but you should always ensure to check if the product features match your RV power needs.

4. Warranty

Finally, you should also check if your product comes with a warranty. Since an RV extension cord is an electrical appliance, it helps to have a warranty to guarantee the quality. Consequently, a warranty will ensure that you don't use a lot of money buying different products if they have faults. Notably, the best 30 amp power cords with the best warranty are more pricey.
