AC Charger vs. DC Charger: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 7, 2023
An AC charger converts Alternating Current to a suitable charging level, whereas a DC charger supplies Direct Current to charge devices or batteries directly.
Key Differences
An AC charger primarily deals with alternating current, implying the electrical charge periodically changes direction. A DC charger, on the other hand, ensures the electrical charge flows in a single, consistent direction, providing direct current to the device.
The AC charger typically involves a conversion process, wherein the alternating current from the power source is converted into a stable form to charge the device. A DC charger, conversely, often bypasses such extensive conversion, supplying the consistent current directly.
Utilization of an AC charger generally facilitates charging through standard wall outlets, which usually supply alternating current. Conversely, a DC charger is generally found in scenarios where rapid charging is required, and direct current is supplied, such as electric vehicle charging stations.
In the context of electrical vehicles, an AC charger usually offers a convenient but slower charging option. In contrast, a DC charger is known for its capability to provide a significantly faster charging experience, albeit with a more complex infrastructure.
Safety and design aspects of an AC charger typically lean towards being user-friendly and are widely available for various applications. While a DC charger, due to its rapid charging capabilities and direct supply of current, often entails a more specialized and robust build, catering to specific applications like industrial use or electric vehicle charging.
