In the past few years, we have covered plenty of clever iPhone cases here. The Thunderocket is also worth a look. It is a wireless charging case that comes with two ports to charge your devices (Lightning and Type-C). When you plug in the Type-C cable, the case becomes a wireless charging pad with varying charging speed from 10W to 7.5W.
The case is also pretty sturdy, so it can protect your phone against daily accidents. In fact, it is 1M drop tested. Once you flip the case over, you can use it as an Apple Watch charger. Like what you see? You can find this project on Kickstarter.
