A:AnswerHi, Jay. The phone charger will work with a phone case that is not more than 3mm thick. As to the AirPods charger, it is molded to the size of the AirPods case and if the waterproof case is too large and thick, it may not align properly.
A:AnswerHi, Mariann. The Belkin WIZ001 is compatible to work with AirPods 2nd generation, and AirPods Pro, and is designed to work with Qi™-compatible devices only.
