A 3V DC mini vacuum pump is a small pump powered by a 3-volt direct current (DC) power supply. These pumps are often used in applications where a compact and portable vacuum source is needed, such as in electronic devices, medical equipment, or small-scale experiments. They function by creating a vacuum or low-pressure area, allowing them to suction air or other gases from a confined space. These pumps typically have a small capacity and are designed for low-pressure applications rather than heavy-duty industrial use.
