Extensions cords are a great to use when working with gear that isn’t battery operated. They provide a consistent source of power that allows for constant usage of an item without having to worry about a battery dying or malfunctioning.
Using an extension cord properly, though, isn’t as easy as “just plugging it in.” There are several factors to consider when procuring an extension cord: the safety of workers, the environment, and the item itself. The bottom line when using an extension cord is this: You want to ensure the cord’s specifications match what the device or object needs in order to function. If the extension cord supplies too much power to the device, it could overheat or malfunction, and the cord could begin to melt. On the other hand, if the extension cord supplies an insufficient supply of electricity to the device, then the device could malfunction and become permanently damaged. 
So how does one know what type of extension cord to buy?
