OTG Adapters

[Android Central Question]

Hi

I'm looking to buy a USB-C Adapter to transfer files from external hardrives to my Huawei P10. Dose anyone know if all Adapters require external power like a PowerBank to be recognised by the Phone? Or can certain adapters get power from the phone?

If so dose anyone have any links to any items on Amazon.

Thank you.
