*Why is the new charger size specific?

The new Oura chargers are ring-size specific, which means, for example, that you can only charge a US6 size ring with the US6 size charger. The wireless charging allows for a seamless inner molding for the ring, but also requires an exact fit between the ring and the charger to ensure good contact.
