To read an AC adapter label, first identify the input and output specifications, which are typically listed in volts (V) and amperes (A). The input indicates the voltage and frequency the adapter can handle from the power source, while the output shows the voltage and current it supplies to the device. Additionally, check for polarity symbols, which indicate the direction of current flow, ensuring compatibility with the device's power requirements.
