How to Choose the Correct HP Pavilion Laptop AC Adapter - An assessment on Voltage, Watts, and Amps
An HP Pavilion laptop AC adapter has 4 key components. You should understand these matters first before buying the charger. This will assist to choose correct adapter.
1. Voltage is energy per unit of charge. Choose correct voltage for your laptop. Most HP laptops have 18.5v or 19v. A 19 volts charger can be utilized on laptop that will need 18.5v. If possible try to get a charger that is exactly if possible.
2. Amps are another thing to consider on laptop ac adapters. Quantity of current is measured in Amperes also called Amps or A. Most H . p . notebooks require 2.7A - 6A. Greater part of them with 3.5 to 4.9A.
A charger with higher amps is fine on a laptop that requires lower amps. By way of example if your laptop uses a power supply of 2.7A then the 3.5a or 4.9a is fine on your laptop. If your laptop needs a 4.9a then the 3.5a or 2.7a won't work on your laptop.
3. Wattage is another factor on the ac adapter. Watts also called as W. Watts are calculated as Volts multiplied by Amps. So W = V x A. In case your HP laptop requires 19v and three.5a then it will be 19 x 3.5 = 66.5w. This means you will need to buy a 65w charger.
Note that the majority of of the chargers won't exactly provide Watts; you are able to safely buy the charger so long as Volts and Amps are matching.
A power adapter with higher wattage might be advisable for your notebook. By way of example if your computer has 18.5v and three.5a or 2.7a then you can consider to buy 65watts adapters. When your laptop needs 4.9a then you definately must buy a 90watt power cord.
4. Last point to consider is connector tip that connects to the pc. HP has yellow tip or bullet pin type or Center pin type or big Yellow tip. Pick the right connector.
