Why an Extension Cord for Your Electric Car Charger is a Must-Have

As an electric car owner, I have come to realize the importance of having an extension cord for my car charger. At first, I thought it would be unnecessary since my car came with its own charging cable. However, after a few months of owning the car, I quickly realized that having an extension cord was a game changer.

Firstly, not all charging stations are conveniently located next to parking spots. In fact, there have been many instances where I had to park further away from the station due to limited availability. Without an extension cord, this would mean that my car wouldn’t be able to reach the charging station and I would have to find another spot or wait for it to become available. Having an extension cord allows me to park in any spot and still be able to charge my car without any hassle.

Moreover, on longer road trips or when traveling to remote areas, having an extension cord has been a lifesaver. There have been times where there were no charging stations nearby and my car’s battery was running low. Thanks to my extension cord, I was able to charge my car using a regular outlet at a nearby gas station or motel.

My Buying Guide on ‘Extension Cord For Electric Car Charger’

As an electric car owner, I understand the importance of having a reliable and efficient extension cord for my car charger. With the increasing popularity of electric vehicles, it is essential to have the right equipment to ensure a smooth charging experience. In this buying guide, I will share my knowledge and experience in choosing the best extension cord for an electric car charger.

1. Determine your Charging Needs

Before purchasing an extension cord for your electric car charger, it is crucial to determine your charging needs. Consider the length of the cable you require, the voltage and amperage of your car’s charger, and the type of outlet you will be using. This information will help you narrow down your options and choose a suitable extension cord.

2. Look for Quality Materials

Investing in a high-quality extension cord is crucial to ensure safety and durability. Look for cords made from heavy-duty materials such as copper or aluminum, which can withstand high temperatures and frequent use. Avoid purchasing cheap cords made from low-quality materials as they can pose a safety hazard.

3. Check the Amp Rating

The amp rating indicates how much current can flow through the extension cord without overheating or causing damage. Make sure to choose an extension cord with an amp rating that matches or exceeds your car’s charger amperage. Using a lower amp-rated cord can result in overheating or even damage to both the cord and your vehicle.

4. Consider Length and Gauge Size

The length of the extension cord is another crucial factor to consider when buying one for your electric car charger. Longer cords are convenient but can cause voltage drop if not thick enough to handle the distance between the outlet and your vehicle’s charging port. It is recommended to choose a shorter but thicker gauge size (lower number) for optimal performance.

5. Look for Safety Features

Safety should be a top priority when choosing an extension cord for an electric car charger. Look for cords with built-in features like overload protection, surge protection, and ground fault circuit interrupters (GFCI). These features can prevent electrical shocks, fire hazards, and damage to your vehicle’s battery.

6. Compare Prices

Extension cords come in various lengths, gauges, and brands; hence their prices can vary significantly. Before making a purchase decision, compare prices from different retailers or online stores to get the best deal without compromising on quality.

7. Read Reviews

Reading customer reviews online can give you valuable insights into the performance and durability of different extension cords available in the market. Make sure to read both positive and negative reviews to get a well-rounded understanding before making a purchase.

In conclusion, investing in a high-quality extension cord for an electric car charger is essential for safe and efficient charging experience at home or on-the-go. By considering these factors mentioned above, you can make an informed decision and choose an extension cord that meets your needs while ensuring safety and longevity.
