I would like to add an external touch screen and backup hard drive to the only USB port without frying the laptop or slowing it all down.

A specific model/product number would be appreciated. (Please do not post serial numbers on the HP Support Forum)
Information on how to find a laptop's model/product number is detailed in this HP document.
I would expect that you are referring to the laptop's USB-C or Thunderbolt 3 port as this kind of setup would be extremely unstable through a conventional USB port.
Awaiting your response,
