HOW TO CHOOSE CORRECT AC ADAPTER FOR YOUR LAPTOP / NOTEBOOK
Choosing the correct laptop ac adapter is all a matter of voltage, output power, and proper connection. If all of these things do not match the original specifications of your current laptop ac adapter, than a new laptop adapter will likely not work on your machine, most laptop ac adapters will have a list of models they are compatible with and a list of part numbers that will work per laptop model.
The first thing to consider in a notebook / laptop ac adapter is the voltage (V). The easiest way to check this is to turn the computer over and see if there is a voltage listed anywhere on the bottom of the machine. A sticker may be affixed with this information and other similar laptop specs listed. It should be a number with a (V) such as 19.5V / 19V / 18.5V / 20V etc.
Secondly to consider in a notebook / laptop ac adapter is the Amperes (A). It should be a number with a (A) such as 3.42A / 474A / 4.62A / 5A / 3.95A / 3.5A etc.
Thirdly to consider in a notebook / laptop ac adapter is the Connector or Tip/ Pin which goes in your laptop and for this you can check our listings which has pin size / Picture mentioned
This information is also available on the original adapter, if it is available to you. If you do have a current working notebook ac adapter then your best bet is to buy the same exact Volt & Amps or part number that is on the laptop ac adapter itself.
