I enjoy reading posts about the tools people use. Casey recently posted about some of his travel toolkit, including a 5 USB port charger.
I can definitely see this being valuable for travel, but my current use case is my bedside table. The charger happily accommodates my iPhone, iPad, and Apple Watch charging cables, plus a micro USB cable for my Kindle and bluetooth headphones with a port to spare. A single box is much easier to manage than individual wall-to-USB warts for each cable/device.
