Can the HP laptop's power adapter be universal?
Hello! Thank you for choosing HP products.
Based on your description, we recommend that you refer to the following information:
Notebook power adapter is generally depends on the adapter interface, input and output of the parameters are consistent, it is recommended that you see the parameters on the power adapter to see if the same, if the agreement then the two machines can be common adapter.
If the power adapter socket is the same as the output voltage can be common.
But there are a few places to note, HP notebook power adapter output voltage there are many, the most common 19V and 18.5V, but even if the output voltage is the same, the output current may be different, that is, the output power is not the same , If your notebook needs a larger input power, then you have to use the match can be, the lower power may not make the battery normal use, and even harmful to the battery.
Power supply low-voltage plug to the same, the voltage to the same, the current is greater than or equal to can be used
