Of course this is doable to turn the portable SmartCharger into a “plugin” regular charger, but with 1 caveat. However, good point raised here that perhaps it’s not that bad as long as it’s still salvageable by turning it into a regular plugin charger.
The screenshot of the manual is shown below says that when plugged in, with the hearing aids inside, it’ll both charge the hearing aids and the battery inside the Smart Charger together, hence the charging time is slower, which is fine. But what we don’t know (hence the caveat) is that whether this would be still working the same way or not if the built-in battery for the SmartCharger is completely dead and not even rechargeable anymore.
The answer is that it depends on the design of the device. Some laptop allows you to have a completely dead and even non-rechargeable battery inside, but as long as it is plugged into a power source, it’s completely operational. If the SmartCharger is designed like that, then the caveat above goes away and you can turn it into a regular charger, regardless of whether the source is from the power wall through a plugin brick, or the source is from a power bank.
Until somebody, or Oticon Support, can confirm that this caveat would not be a concern, we just don’t know until then.
