Suitable e.g. as: -Adapter for tablets to add or directly connect mouse/keyboard/Bluetooth devices with corresponding receiver (Have a Samsung tablet with keyboard, with a similar adapter I could connect a wired mouse as a laptop replacement). -Data transfer -etc.
Everything that can be connected to a USB can be connected.
I would continue to use the standard USB-C cable for fast charging without using a large adapter, as the specifications usually state the possible charging power (depending on the source and the receiving device).
