Cordless devices are electronic gadgets that operate without being plugged into a power outlet. They typically use rechargeable batteries, allowing for greater mobility and convenience. Common examples include cordless phones, cordless vacuum cleaners, and cordless power tools. These devices are designed to make tasks easier by eliminating the hassle of tangled cords and limited reach. The technology behind cordless devices often involves wireless communication, such as Bluetooth or Wi-Fi, for connectivity. This allows users to enjoy the freedom of movement while using the device. As battery technology improves, cordless devices continue to become more efficient and longer-lasting, making them increasingly popular in everyday life.
