FWIW, a Nintendo Switch USB-C to HDMI cable with power input travels well for this, albeit a bit bulky.

This one puts the charger input at the HDMI end where the TV and presumably outlets are, so power comes to your video playing device over the USB-C at your device end.

In 1955, Zenith introduced the Flash-matic: world's first wireless remote control, so people wouldnt need to have a really long wire connecting their remote to their television.

I guess that could "work" but it sounds like a bit of a hassle. Perhaps an old iPad could be used.
