What happens if you add a second or third grounding adapter to a device such as the laptop?

 I like to give appreciation for the help I was given by Shaun for my grounding questions he answered. Right now, the package has been successfully delivered to my address despite the long wait due to COVID-19. I would also like to thank the technicians I called over the phone as well for answering my inquiries of the delivery status.

Anyway, I have another question to ask here. My laptop is currently plugged to a USB grounding adapter I purchased from this site. The results before and after were astonishing. Before, my meter picked up the electric fields of beyond 1000 v/m (disastrous). After, my meter picked up the electric fields of under 200 v/m. I think the average is around 140 v/m even though it was still beyond the safe recommended level of ELF.

Now, what happens if I were to add a second grounding adapter to this same laptop by any grounding sources such as this one below,

or

or

Any monitor or printer with a cord of 3-prong plug?

What will also happen if I added a third grounding adapter? Will it reduce electric fields as low as I need it to be? Or will there be repercussions such as ground loops? This is a question I'm not sure about but would like to know. Please let me know what you think.


Thanks,
