Finding the right AC Adaptor for your laptop or notebook...

Most people refer to these as chargers but they are technically an AC Adaptor.

In the most basic of forms, AC Adaptors convert AC mains power (100-240V) to a smaller DC voltage for use with devices.

Finding a suitable Laptop AC Adaptor is a very simple 3 step process;

  1. Voltage (V)     input voltage required by the device (found on the rating label)
  2. Current (mAh) input current the device consumes (also found on rating label)
  3. Connector       size and polarity of the connector itself.
