AC Charger vs. DC Charger: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
An AC Charger converts Alternating Current (AC) from power outlets to Direct Current (DC) for device use, whereas a DC Charger directly supplies DC power, often used in fast-charging applications.
Key Differences
An AC Charger is typically used in household electronics, converting the AC from wall outlets to the DC required by most electronic devices. This process involves an internal rectifier.
