Difference between AC and DC Chargers

Main Difference

The main difference between AC and DC chargers is that AC chargers are supplied with alternating current, that is, the current switches back and forth. This is the main reason why we have AC current, in the electricity lines, at our homes. On the contrary, DC chargers are supplied with direct current, that is, the current does not shift or switch back and forth. In DC chargers, It is simply the positive and negative type of current. So, precisely, AC current chargers are a bit complicated than DC current chargers.

AC Chargers

AC chargers contain a transformer which transforms the electricity voltage coming from main line to a lower voltage and it also contains a rectifier which converts it to direct current. They are used largely to charge big and small, portable and non-portable electric devices.

DC Chargers

It has filtering components; these components keep a check on stability of the direct current. DC chargers are basically simple chargers. DC chargers do not change their result on the basis of the time duration for which the battery has been put to charge.

Key Differences

  • DC chargers are inexpensive while AC chargers are expensive as compared to the DC chargers.
  • DC chargers take longer time to charge the battery, while AC chargers charge the battery in comparatively shorter length of time.
  • AC outlets and power sockets are more convenient. While DC charging stations have special grid for more power production.
  • DC chargers can supply a constant voltage or current to the battery while in the case of AC chargers, the current and voltage shifts.
  • The expected life of an AC charged battery is greater than a DC charged battery.
  • AC chargers are used more in homes as compare to the DC chargers.
  • AC chargers can damage some electricity circuits, which are specially designed for DC chargers.
  • DC chargers can cause excess heat in some electrical appliances as compared to the AC chargers.
