Combining 2 5v devices to a single power cord

Hey everyone, I’m new here so my apologies if this is in the wrong section.
I got an old black and white tv and I’m working on converting it to accept HDMI so I can run a streaming device.
with the TV, the HDMI to Coaxial adapter, and the streaming device, there would be 3 power cords. The TV runs off ac, the other two have a power cord that convert to DC. I don’t want to dive in to making a single cord for all three, so I’ll focus on trying to combine the two DC components.
the two components are
-5v 500ma
-5v 1a

from all the reading I have gathered that I need to combine the two Amps, so a cord that is 1.5A
my question is, do I combine the 2 volts required(10v) or just keep it 5v?
or am I going at this all wrong?

thank you

If I'm understanding your problem correctly you just need 5V DC at 1.5A. Perhaps think about finding something at 2A to give a little leeway.

Sorry if im making it confusing, this is my first electrical project, so I could be muddying up the waters haha.
basically, if two components that take separate power cords where made to share a single power cord, would I need to add the volts of the two or keep it same shared value
