BGR wrote a great article on different uses for your iPhone’s USB-C port besides charging. For example, you can connect a wired keyboard to your phone and start using it without any further configuration. Or you can hook up an external hard drive or USB thumb drive to transfer or even back up some of your files while on the go. It might be the faster or only option at times. They even suggested plugging in a wired game controller, but my favorite suggestion was to plug in and charge your low-power devices like AirPods or Apple Watch on the fly. In fact, I have a pretty cool Apple Watch travel charger to do just that. It gets you out of a pinch, for sure.

Not mentioned in this article, but something else I have tried in the past, is plugging in a USB ethernet adapter to connect directly to a network and run a couple of diagnostic tools. Fun stuff. I have also connected USB-C hubs to power multiple devices and even output video over HDMI to an external monitor. I guess the sky is the limit. When in doubt, try it out.
