There are several types of DC jacks, including barrel connectors (the most common type, available in various sizes like 5.5mm x 2.1mm and 5.5mm x 2.5mm), snap and lock jacks, and USB-based DC jacks (such as USB Type-C for power delivery). Each type varies in size, shape, and current rating to suit different devices and applications.
