The symbols on a power adapter indicate important information such as input and output voltage, current, polarity, and certification marks (like CE or UL). They show if the adapter is suitable for your device and if it meets safety standards. Common symbols include a line over a dashed line for DC, a tilde (~) for AC, and a diagram showing whether the center pin is positive or negative.
