The vampire power supply is the power used after the appliance or electronic device is turned off.While many appliances do use a vampire power supply, it is not used to plug in extension cords.
Even if nothing is plugged in, some wires suck out the power of vampires.Extension cord is an exception.The cell phone charger wire is an example of a wire that draws power even if it is not plugged into the cell phone.One way to tell if the wire is using the power supply is to touch the adapter it plugs into the wall.If the weather is warm, it is likely to use electricity.
According to US media reportsS.In the US Department of Energy, vampire power accounts for 25% of the electricity used by household electronic devices.Also known as a virtual power supply or a backup power supply, the internal clock and power supply in these devices use this power supply, allowing them to quickly turn on and save data in memory.
Although the extension cord itself does not consume the power of the vampire, if the electronic device is plugged into the wire, it may consume power even if it is powered off.In addition, the long-term use of the extension line will bring fire hazards, so it is better to use the extension line only temporarily.
