Products like the iPhone aren't capable of wireless charging straight out of the box, which is much to the chagrin of users, so the 'Stacked' iPhone Wireless Charging Solution is designed to help enable a truly wireless experience.
Rather that being a battery case that loses charge and needs to be plugged in, the 'Stacked' iPhone Wireless Charging Solution works with a magnetic connectivity system that allows interchanging of power packs.
When a power pack dies, simply attach a freshly charged one to keep going. The home base for the 'Stacked' system can charge up to five power packs at a time, which means going without energy will never happen again.
Working with the 6, 6 Plus, 6S and 6S Plus, the 'Stacked' iPhone Wireless Charging Solution frees Apple users from cords.
