I have just had another look at the links you posted. The three in your first post all appear to use USB3 Type A connectors, the four in your #3 all appear to have USB C connectors.
USB 3 and USB C are not interchangeable - they won't fit each other's sockets. USB 3 Type A connectors look like any other USB Type A that have been around for years - about 11mm wide, 3mm deep with a plastic 'tongue' taking up about half the internal depth. In the case of of USB 3 these tongues are normally blue. USB C uses a socket with a tongue in the middle of the internal space and the connectors are on either side of ths central tongue.
To the best of my knowledge and belief, the maximum power you can get out of a USB 3 socket is 4.5W (5V x 900mA). You can get more, possibly much more, out of a USB C socket but you need to know its ratings and the place to find this infomation is the computer manual. You may need to go to your manufacturer's web-site to download a copy of the manual, typically this information is no longer shipped with the computer ! I just spent several hours this afternoon setting up a brand new laptop for my sister-in-law and the documentation that came with it just about showed you the power button and where the CD drive was. OK, not quite, but not much more !
