[ Firstly this question doesn’t violate Rule No. 3 of the Community, as I need technical help not economical ]

I want to buy a 3.5" SATA HDD to USB connector.

I found this https://www.amazon.in/WeFly-USB-3-0-SATA-Adapter/dp/B0CWS2DZKV/

As far as I know, 3.5" SATA HHD needs extra power supply. This adapter I found Amazon has separate 12V/2A port ( power adapter not included). Also it has 2 USB ports.

Now, my question is will the second USB draw the power needed from the Laptop itself? Or do I must have separate power supply?

If the answer is the latter, why is there a second USB?

I do already have a 12V/1A power supply. But my HDD requires 5V/0.75A + 12V/0.75V.

Idk If this Community the is appropriate one for this question? Maybe because I includes Ampere?
