USB2 and USB3.
USB2 max output is 0.5A. Not much. With an A/C adapter, it could
supply more amps, but that would require the power connector on the
converter to supply from the power adapter instead of from the USB port.
The Vantec diagrams show connecting it to a USB3 port (0.9 amps). For
USB2 ports, you might have to use a Y-cable that connects to 2 USB2
ports. Before USB3 became common, I had a USB HDD in an enclosure with
no external power (no A/C adapter) that wouldn't work (rarely would even
spin up) unless I used the Y USB cable.
For the setup where the 2.5" pushes simultaneously onto both the SATA
power and data connectors, there is no way to connect the A/C adapter to
the drive. All that drive's power comes through the SATA power
connector, and that power comes from the USB port. Only when you use
the A/C adapter with the power cable going to the drive is the A/C power
source used.
At the Amazon page you gave, there are setup diagrams. In the config
with 2.5" SATA drive, the A/C adapter is not used. The drive gets its
power through the converter which gets its power from the USB port.
Try using a USB3 port whenever possible.
The oldest drive was a laptop/notebook's HDD from the 90s.
That would be a spinner (HDD), so check it is not jumpered for CS.
