May be I should have asked:
Should ANY laptop power adapter be grounded?
As a computer repair tech, I always wondered why some power adapters for laptops come with a ground pin on the AC plug and others don’t.
Example: Macbook Pros in the UK have 3-prong AC plugs with an actual metal ground pin.
Other laptops I’ve seen have a plastic (dummy) ground pin or no ground pin on the AC plug.
I’m planning to buy two Universal Power Adapters:
Should they have a ground prong on the AC plug?
Any advice much appreciated.

I’m planning to buy two Universal Power Adapters:
- USB-C Power adapter (up to 100w with USB-A and USB-C ports)
- Multi-tip Universal Power Adapter for all laptops (barrel tips).
