I was visiting a friend recently and he had the coolest USB cable I’ve seen. On one end it has a standard USB connector and the other had multiple connectors that fit most any gadget released in the past few years.
It is not the longest cable and it is only good for charging. But the convenience of having plugs for most every device is awesome. If nothing else you should keep one of these in your home or office in case a guest needs to charge their device.
It costs about a dollar more, but the Vastar cable is a nice alternative.
