Extension cords are made with being laid out the typical use and allows maximal cooling from high current and resistive losses. If coiled up and under high current loads they may well become a fire hazard and catch fire. Extension cords should not be used tightly coiled.
Can you use an extension cord rolled up?
The normal cable ratings assume that the wire can adequately disperse heat generated in the cable due to the current flowing. If you coil it up and use close to the maximum rating then it stands a good chance of melting the plastic insulation and then causing a short.
Is it safe to coil electric cords?
But an electrician told me; if you are using a cable, coiling (wrapping) cables is wrong. It could damage your computer, electronic devices, etc. You should un-wrap cables of devices if you want to use them.27 Sept 2018
Does coiling a wire damage it?
The danger comes when the heat generated by the current flow cannot be dissipated. While tightly coiled DC cables can generate enough heat to damage the insulation and cause shorts and fires, the danger is even greater with AC circuits.
Why does a coiled cable get hot?
Coiled Wire If you roll up wire into a coil, such as an extension lead and then plug in an appliance, you will find the wire starts to get hot to the touch. This is because of the resistance and magnetic field produced by the electricity passing through the coiled wire.
Is it safe to plug an extension cord into a surge protector?
Using an extension cord with a surge protector is a fire hazard at worst, and at best runs the risk of damaging or degrading the cords of either component. Don't use a high-current surge protector with a low-current cord, and if one component uses a 14-gauge wire, the other should as well.

What is safe to plug into a power strip?
Most people don't know that power strips are only designed to handle electronics that draw very little power, relatively speaking. A power strip can safely handle AV equipment or low-power household items like smartphones, tablets, laptops, or lamps.9 Oct 2020
Can you plug multiple extension cords into a power strip?
Extension cords and power strips are not to be used together.
