Choosing the right Laptop ppp009l AC Adapter is a way to ensure your work smoothly. Here in this post, we are talking about the 4 important ratings (Voltage, Watts, and Amps) when choosing an ac adapter for your laptop computer.
[1] Voltage. Voltage is energy per unit of charge. Choose correct voltage for your laptop. Most laptops have 18.5v or 19v. A 19 volts charger can be used on laptop that needs 18.5v. If possible try to get a charger that is exactly if possible.
[2] Amps. Amps are another thing to consider on laptop ac adapters. Amount of current is measured in Amperes also called Amps or A. Most notebooks require 2.7A - 6A.
A ppp009l charger with higher amps will work on a laptop that requires lower amps. For example if your laptop needs a power supply of 2.7A then a 3.5a or 4.9a will work on your laptop. But if your laptop needs a 4.9a then a 3.5a or 2.7a will not work on your laptop.
[3] Wattage. Wattage is another factor on the ppp009l ac adapter. Watts also called as W. Watts are calculated as Volts multiplied by Amps. So W = V x A. So if your HP laptop requires 19v and 3.5a then it will be 19 x 3.5 = 66.5w. So you will need to buy a 65w charger.
Note that most of the chargers will not exactly provide Watts; you can safely buy the charger as long as Volts and Amps are matching.
A power supply adapter with higher wattage will be advisable for your notebook. For example if your computer has 18.5v and 3.5a or 2.7a then you may consider to buy 65watts adapters. If your laptop needs 4.9a then you must buy a 90watt power cord.
[4] Last point to consider is connector tip that connects to the computer. HP has yellow tip or bullet pin type or Center pin type or big Yellow tip. Choose the right connector.
