How to choose a suitable AC Adapter for your laptop? . You should be very cautious when you buy an AC Adapter for your laptop. If you try to power your laptop using an inappropriate AC adapter it will damage your laptop. There are three primary factors you need to consider before buying; namely voltage, amperage and tip size. Determine the desired output specifications of the AC adapter. This can usually be found on the old adapter. When selecting an adapter, you will want to match these as closely as possible. Instructions: Step1:Identify the voltage. Next to the word "output", you'll see a number with a "V" after it (such as 19V). This is your voltage. Step2:Identify the amperage. After the volts, there will be another number with "A" after it (such as 1.58A). Step3:Determine the size of the adapter plug. Plug sizes are normally measured in millimeters.(Such as 5.5 mm * 2.5 mm) , Choose an adapter that meets all of the above three requirements: proper output voltage and current, proper plug size, and proper power cord. If an exact match is not available, it is better to err on the side of the new adapter having a higher current than the specifications require. For example, if the device calls for19 V 3.16 A, it is Ok for the new adapter to provide 19 V 4.74A (higher current) .
