You really don’t have to go wireless to protect your device/battery against the elements. In fact, most smartphones today are totally waterproof while still being charged by a good old cable. It’s also pretty easy to design a connector with exposed pins that are totally inoffensive until something real is exposed. In fact, modern USB charging already works like this : a charger will not send anything over 5v x 150mA before having negotiated with the device to know what it needs.
