Depending how far back I am going, my smartphone would be sufficient. Even without any kind of connection, it can do some rad stuff that would blow the minds of anyone in the 90’s or earlier.
Take a photo of them. Then zoom in. If that doesn’t blow their minds, take a video of them and play it back.
Digital cameras have been commercially available as early as the late 80s, but were of course super low res and with terrible image quality even accounting for that compared to what I just carry in my pocket now.
Charging wouldn’t be that difficult either if its pre USB-C. A nice steady 5V trickle at two visible connectors. Get yourself a nice thin copper wire with the right number of turns along a rotating magnet, and crank that handle gently
