i used the charger that plugs into docking station separately.It obviously has more voltage than the laptop charger – user1293017 Apr 02 '21 at 06:27

It's completely safe.
Electricity has voltage measured in volts V and current measured in amperes A.
The voltage of a power supply must match what the device expects with ±5% tolerance (sometimes more). The docking station certainly uses the same voltage as the laptop, so you're good here.
The current works a bit differently. It's not "pushed" into devices, but "pulled" from the power adapter. The adapter won't "push" all the current it's capable of providing if the device is not willing to consume it. The device will use as much power as it wants and the adapter will be working at a fraction of its max current.
