USB-a works well, USB-c passthrough charging works poorly

The product works well enough for everything but charging. When a PS4 controller is plugged into the adapter, as well as a USB-c fast charger, the adapter wont actually charge my galaxy s9 plus. That said it does drastically decrease the rate at which my battery drains while playing a ps1 emulator. Over all not what I had hoped it would be, but very usable and a means to do what I wanted. 4/5
