Rechargeable devices are electronic gadgets that can be powered again after their energy source has been depleted. They typically use rechargeable batteries, which can be charged multiple times, making them more environmentally friendly and cost-effective compared to single-use batteries. Common examples include smartphones, laptops, and electric toothbrushes. These devices often come with a charging cable or dock, allowing users to connect them to a power source, such as a wall outlet or a USB port. The convenience of rechargeable devices has led to their widespread adoption in everyday life, reducing the need for disposable batteries and promoting sustainable energy use.
