A wide variety of household appliances gives rise to the variability of their connection to the network. A new garden appliance may well not work if connected to a low power extension cord. A power strip is needed for electrical appliances whose power is so high that they cannot be installed directly into the outlet or through a standard extension cord.
As a rule, such a need arises during repairs: most power tools have a lot of power. The next aspect that attracts users in power extension cords is the length of the wire; without a wire of sufficient length, it is almost impossible to work in a summer cottage.
