Portable projectors are often battery-powered, making them easy to take on the go.
Portable projectors use a variety of technologies, including DLP (Digital Light Processing) and LCD (Liquid Crystal Display), to produce high-quality images. They often have built-in speakers and can connect to devices via HDMI, USB, or wirelessly using Bluetooth or Wi-Fi. Some portable projectors also have built-in streaming capabilities, allowing you to access content from services like Netflix or YouTube directly from the device.
