Rechargeable hearing aids have one problem, which is that when you run out of battery, you have to put it on the charger for at least an hour to get the rest of the day’s operation of the hearing aid.
I have a strange idea, maybe an inductive power charger will offer something that the older type of plug-in chargers didn’t.
Try to imagine if Phonak or any other manufacturer offered for sale - a charger in the form of a headset. Those headphones would actually be a power bank that would supplement the hearing aid with inductive charging even when we wear the hearing aid.
People would probably think that we are listening to music, but we are actually charging the hearing aid.
I think that the hearing aid must be able to distinguish between a desktop charger and a charger in such a way that it can be turned off while charging on the desktop charger and still work when we wear such headphones.
