My HP Specter x360 (13") came with a 20V charger.
I just got a new HP docking station, however it's rated for 19.5V .
It looks liKe the docking station is chargging (Via Thunderbolt 3).
Do I need to worry about the voltage differance?
Thanks

Hi! @mbar1, Welcome to HP forums.
I understand that you got a 19.5V docking station and you need to know whether it would be a problem if you charge your laptop.
Don't worry I will try to help you out.
Is the docking station compatible with your PC?
The following will cause damage to your device:
Reverse polarity
Higher voltage adapter than device rating
The following will cause harm to your power cord or adapter:
Reverse polarity
Lower current adapter than device rating
The following might not cause damage, but the device will not work properly:
Lower voltage adapter than device rating
Higher current adapter than device rating
So, please buy a compatible docking station for your PC.
Hope this answers your query!
Have a great day ahead! 🙂
