Having to carry multiple cables to charge your gadgets on the road is not ideal. The Weast 3-in-1 Zipper Charging Cable comes with everything you need to charge your iPhone, Apple Watch, and laptop. You can open or close the zipper to adjust the length. This cable has a 27W Lightning and 65W USB-C head in addition to an Apple Watch charging head.
You can get this cable to 2.2 meters when fully unzipped. You can find this project on Kickstarter.
