I have a problem, I love USB battery packs and my collection keeps growing, it is getting so bad that I am running out of space in my backpack. Many of my USB battery packs have a similar set of features, the ZMI 20,000 mAh Battery Pack is very different as it not only puts out enough power to charge my PixelBook at full speed but it pulls double duty by acting as a USB 2.0 hub at the same time.
I don’t know of any person who works in technology who will can doubt that the USB standard was one of the most disruptive technologies to the computer world since the launch of the World Wide Web. Shortly after being launched in the late 90’s, the USB standard has made several technologies such as Parallel Ports, DB9 Serial Ports and even Floppy Disks obsolete with little effort. The newer Type-C USB port along with USB 3.1 that has started making its appearance on devices in 2015 stands to render several technologies that we use today obsolete, here are just 6 of them.
