USB OTG Type-C vs 3.0 USB C OTG Thunderbolt 3
I do not understand why you need an adapter from type-c to type-c - the connectors are the same and it is not curved, i.e. it seems that it is just a 2 cm extension cable, which is strange.
Title:
CABLETIME NEW USB OTG Type-C Adapter to 3.0 USB C OTG Thunderbolt 3 USB Type C Adapter Cable for Macbook Pro Samsung S9 C013
Description:
Cabletime USB C Type-c USB Type C Adapter USB 3.1 Male Adapter connects USB-C enabled device such as letv Smartphone, Nokia N1 tablet to a computer or USB charger for data transfer or charging with a Type-c cable. It upgrades your type-c USB charging cable to a USB 3.1-Type C Data Cable and charging cable, saving you the cost of buying a new one. Connectors
According to the description, it turns out that it can "teach" a cable that works only for charging to transmit data? But is that possible? The name says that this is an adapter from USB OTG Type-C to 3.0 USB C OTG Thunderbolt 3 - do they differ in some way? And are they compatible without an adapter?
All 11 reviews have a rating of 5 out of 5, some even say that everything works, but no one has explained what exactly works there. Why do I need such an adapter?

Here is the picture for the OTG adapter to the AF connector. Here, to transfer the USB port to host mode, the CC output is fed through a resistor. The Type-C connector was originally for Apple laptops and the "host" mode on it was by default and the power supply was constant. Under this specification, devices began to be produced.
In modern devices, this resistor must be soldered into the connector, but if you connect such a device via a cable in which the CC line is not wound up or the device does not match specifications 3.1, then the phone will not supply power and it will not work. This adapter tells the phone to turn on the power.
