This doesn't have a usb-c connector, it has a micro usb connector. the product photo and description are misleading.

It's called C-type input and sends a 5-pin connector.

Secondary function, plug in usb charger, plug in led light, when the power goes off the led comes on.

Excellent product with a hidden feature, plug in a charger and a short cable with an led, when the electricity/charger goes off, the led comes on, like an emergency light!
