How to Buy the Best Extension Cord for Tesla?

Well, there are lots of cords available on the market but you need the best one for you. I have already mentioned the products I found to be the best to charge your vehicle.

However, if you still want to explore more and wish to choose one by yourself, I'm still here to help you. While choosing the right extension cord, you may ask, ”œDo I need to use a specific extension cord to charge my Tesla?”

Well, the answer is ”œYes”, you should always use the same specific cord to charge the vehicle. And there are some considerations you should make before buying any extension cord.

Choose the Right Length

The very first thing you need to look for is the length of the cord. You must look for a short in a long extension cord for Tesla. The cable should be as short as possible as longer cables increase the resistance which results in voltage drop.

That is why most Tesla charging cables aren't more than 30 feet on average. You must not purchase a longer cord more than what you actually need. You should look for an extension cord within 20 to 30 feet.

Higher Insulation

As a proud EV owner, you should know that you can charge the vehicle outdoor, even in the rain. The components of Tesla are waterproof and can be charged without worry. But, don't take it for granted for the extension cables.

If you need to charge outside and it is expected to rain anytime, you should use an extension cord with higher insulation. Cables with high insulation have strong resistance against water and heat.

Heavy-Duty Cable

Make sure your extension cable has ”œHeavy-duty” written on the box. Heavy-duty cords have at least a 12-gauge number which indicates strong insulation. The best 12 gauge extension cord would be perfect but I would recommend going for 10. The lower the number is, the stronger the gauge is.

You may find the heavy-duty cables expensive but they're worth the price considering their strong insulation and low resistance. Also, extension cord with multiple outlets might be a considering option.

Frequently Asked Questions (FAQs)

1. Can Tesla's 110-volt adapter be used with extension cords?

Yes, certainly it is possible to utilize Tesla's 110V adapter to connect with the extension cord which is an excellent way to increase the usable length of the cord.

Final Verdict

The electronic vehicle industry is booming with time. With the increasing number of EV cars, the number of superchargers is also increasing around parking lots, petrol pumps, and other resting areas.

However, at times you may not be able to reach so close to the outlet with your electric car. It may also happen right inside your garage if it is far from a 14-50 NEMA outlet. So, an extension cord comes in handy at times, and storing one in your Tesla is a good idea.
