The term "cordless" refers to devices that operate without the need for a physical power cord. This means they can be used freely without being tethered to a wall outlet. Common examples of cordless devices include cordless phones, cordless vacuum cleaners, and cordless power tools. These products offer convenience and flexibility, allowing users to move around easily while using them. Cordless technology typically relies on rechargeable batteries, which power the device for a certain period before needing to be recharged. This innovation has made everyday tasks simpler and more efficient, as people can enjoy the freedom of movement without worrying about tangled wires or limited reach.
