👉 A cordless fluid, also known as a rechargeable or battery-powered fluid, is a type of energy storage medium that replaces traditional wired power sources in various devices and systems. Unlike conventional batteries, which are typically rigid and require physical connections, cordless fluids are contained within flexible, often gel-like or polymer-based containers that can be integrated into the device's design without the need for cables. These fluids store energy chemically or electrochemically and can be recharged through external power sources, making them ideal for applications where mobility and flexibility are crucial. They are commonly used in cordless tools, drones, electric vehicles, and other portable devices, offering a convenient, lightweight, and efficient alternative to wired power solutions.
