Question about PowerGuard USB-C to Double USB-C Splitter Charge Adapter

It is compatible with any connection that has usb type c and is good for charging 2 devices at the same time, I have currently tested it on the rog ally x rog ally msi claw samsung galaxy s23+ powerbank Baseus and directly on the output of a samsung fast charge charger.

You can assume the splitter adapters on the. cheaper side are meant for charging/audio. Data transfer needs more/more expensive components. I spent 50+ CHF on an adapter for charging/data. All the cheaper adapters did not work.
… can’t tell anything about pixel 7.
