Unless you are always lucky enough to have an electrical outlet positioned exactly where you need it, you almost certainly use electrical extension cords around your home. Extension cords provide power for devices with cables that can’t reach any nearby electrical outlets. An extension cord essentially is a bundle of insulated electrical wires with a plug on each end that transmits power from a power point to your electrical vehicle from a safer or more convenient distance. Extension cords make it easier to charge your vehicle as you don’t have to struggle with precision parking to fit the vehicle near the charger. The extension cords are able to charge your Tesla vehicle with the mobile adapter. Other electric vehicles can also be charged using an extension cord but the products recommended here are specifically for Tesla vehicles.


Before you go shopping for an extension cord, however, there are features you should consider in order to help in picking the right extension cord to your specifications. They include wire gauge and length.


Electrical extension cords come in different types, lengths, and sizes. Two important factors determine any cord’s load capacity, its ability to carry electrical current:


Wire gauge: Gauge is a numerical rating of copper wire diameter and is identified by an American Wire Gauge (AWG) number. For example, a 12 AWG, 120-volt cord contains 12-gauge wires and is intended for use with standard 120-volt outlets. In the AWG rating system, the smaller the number the thicker the wire.

The thickness or diameter of the wire affects how much current the wire can carry and how much the wire heats up.


Length: The length of the extension cord affects voltage drop, or how much voltage is lost through resistance in the cord wires.


Listed below are some of the best extension cords for Tesla you can find on the market at the moment

There are problems that may arise from using extension cords that you ought to be prepared for.

 Electrical current flowing through wires generates heat, and when too much current flows through a wire, it can overheat and melt the plastic insulation of the wires, causing short circuits and fires.

 This is normally not a problem when you plug an appliance directly into an outlet using its factory cord because the manufacturer has sized the cord appropriately for the electrical current demand, or load, that the appliance requires. But if you use an undersized extension cord to extend the reach of that appliance cord, you can exceed the safe load capacity of the extension cord, and the result can be disastrous. This is just a precaution but the overall benefits greatly outweigh the dangers.
