I want to make a product that is completely water-tight but can be charged. On-board energy storage is done with supercaps (50F/2V5) and IO want to charge them via some kind of contactless energy transfer like the way you see in electronic toothbrushes.
Charger and product can be placed on each other to charge but I dont want connectors. Are there any standard components/coils or application notes for this application ? Charge current=100 to 500 mA
I'm mostly worried about CE/UL testing
