Why It's Important To Never Plug Power Strips Into Each Other

Power strips should never be daisy-chained—plugging one into another—because the practice can overload circuits and cause house fires, according to a consumer safety explainer. The core issue is that adding sockets does not increase electrical capacity: all devices on the second strip draw power through the first strip's plug and internal components, forcing it to carry the combined load. Each strip has a maximum amperage rating, and if the first strip is already maxed out, the second strip's draw can push too much current through the wiring, generating "resistive heating" that can melt casings and wire insulation and ignite nearby flammable materials. The risk is heightened in home offices and gaming setups, where work-from-home device proliferation has led to tangled cords and abundant flammable materials. Consumers should watch for guidance on safe power distribution, including using a single strip per wall outlet and respecting amperage limits.
