Taken from the Myriad Case website: "Since their fruition, battery cases have been bulky, heavy, complicated, and much more. We re-imagined the battery case, centered around our own patent-pending wireless charging technology. We call it Myriad Case, and we believe it’s the world’s most versatile battery case for iPhone XS/X. For years, iPhone cases have had one purpose: to protect your phone. While Myriad Case is primarily a battery case, it doubles as a modular smartphone case that can adapt to your life and your preferences."
