How to Choose an Replacement HP Compaq AC Adapter
An Replacement HP Compaq laptop AC adapter has 3 important components. You should understand these things first before buying the charger. This will help you to choose correct HP Compaq nw9440 power adapter.
- Output Voltage and milli-Amps
Voltage is energy per unit of charge. Choose correct voltage for your laptop. Most HP Compaq 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 are another thing to consider on hp compaq nw9440 charger. Amount of current is measured in Amperes also called Amps or A. Most Hewlett Packard notebooks require 2.7A - 6A. Majority of them with 3.5 to 4.9A.
A 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.
- Wattage is another factor on the hp compaq ac adapter. Watts also called as W. Watts are calculated as Volts multiplied by Amps. So W = V x A. So if your hp compaq laptop requires 19.5V 3.34A then it will be 19.5 x 3.34 = 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 19.5 and 3.4a then you may consider to buy 65watts adapters. If your laptop needs 4.62a then you must buy a 90watt power cord.
- Last point to consider is connector tip that connects to the computer.Basically, hp compaq nw9440 ac adapter comprise of 2 ends. One end is male power outlet. You use this end to plug into wall power outlet. The other end is called "TIP" which you will plug this tip into the "DC IN" in your laptop. Your laptop won't work on the wrong tip. You can only use the " matching Tips"
