What are the connecters on esata cable that comes with Penta SAta Hat for rasp Pi

Trying to understand how to connect the eSata port on the Penta Sata hat. I looks like just the cable into the hat - seems to make sense - and appears to look like a sata connector on the other end with just the data cable connected.
How do i get power to the drive?

Read some thing about “power eSata”?

Thanks
