It is really an old topic of how to selecting the right ac adapter for our laptops. However, I just met more than 3 customers who do not know these steps of selecting the right adapters this month, which totally made me wordless.
At earlier this month, a customer bought a replacement ac adapter for her laptop. However, as soon as she received the package and found that the part No. on the cover of the adapter is not exactly the same as her original one, she insisted on that the online shop sent the wrong adapter to her, no matter how we explain the other necessary data of the compatibility of an adapter. It is pretty said to me, as even so many related knowledge showed online, there are still some people turn a blind eye and self-righteous.
I never made any mistakes of selecting the right ac adapter for my laptop. Here is the detailed information of the HP 384021-001 Power Adapter I bought for my laptop from feevoo.com:
Input: AC100-240V (worldwide use)
Output: DC 19V 4.74A
Power: 90W
Connecter size:
Internal Diameter: 5.0mm
External Diameter: 7.4mm
With smart-pin inside
In fact, it is really very easy for us the select the right replacement ac adapter for our laptop online, if we could remember the following simple steps:
1> Check the voltage & current of your original HP AC Adapter. Turn your laptop over and look for a label, sticker or writing which shows the voltage and current, it should look something like the examples below. The voltage figure will have a "V" after the number i.e 19V and the current will have a "A" or "mA". i.e 3.15A. You can also find these shown on your original HP 384021-001 Power Adapter if you have it. The Voltage must be within 10% of your original HP AC Adapter Voltage. The Amps may be higher but they cannot by lower. For example, If the wattage requirement for your laptop is lower than the 60W or 90W output of the adapter, it will not damage your laptop, your laptop will only take the amount of power it requires. If your laptop needs 45W, then either the 60W or 90W will work OK. If your laptop needs 80W then you will need the 90W one as the 75W one will not be powerful enough.
2>Make sure the connection fits the port in your computer where it is to be plugged in. The voltage and output current of the laptop adapter will not matter if it is not able to be connected. Usually, there are 2-prong and 3-prong for selection. If ordering online or if you do not have your computer, it is advisable to check this out as soon as possible.
3> since you just buy the replacement ac adapter, it is unnecessary for us the check the compatibility of the model No. or part No. on the cover of the replacement one.
I really hope that this above knowledge could help you to select the right one. If you wanna buy a new one, you could also go to feevoo.com directly.
