Here is a tiny universal ultra-fast keyring cable that can charge your Apple, USB-C, and MicroUSB devices. It not only supports charging but OTG. It supports charging up to 100W depending on your device. It has a N52 magnet system, so you can carry it with your keys conveniently.
You can even use this cable for phone to phone charging (for models that support it). inCharge X has a zinc aluminum alloy shell and TPU protection for increased bending strength. Like what you see? You can find this project on Indiegogo.
