Smallest smart power outlet

The new ST smart power outlet looks pretty small. Is there anything smaller that plugs in (not wanting to replace the outlet)?

For now ST’s looks the most compact and least intrusive one. Wish they could become even smaller in the future, like an iPhone charger cube size.

While not smaller, I have used these GE outdoor ones for some areas where there isn’t clearance for the regular smart outlets. Also these extenders.

Also these extenders.

Which extenders? They are both linked to GE outdoor outlet. Thanks.

I already have the Aeon Labs Smart Energy Switch but am looking to plug something into a kitchen under cabinet plug mold and the aeon one is too bulky. I think I’ll try the ST one.
