A cordless projector, also known as a wireless projector or a battery-powered projector, is a portable device that can project images, videos, presentations, and other content onto a screen or surface without the need for direct power connections. It is equipped with a built-in battery that powers the projector and eliminates the need for a constant power source during operation. These projectors often have wireless connectivity options like Wi-Fi or Bluetooth, allowing you to connect your devices such as laptops, smartphones, or tablets wirelessly and project their content onto a larger screen.
