Will any other charger work with Oticon hearing aids?

Chargers are specific to each type of HA’s. Not interchangeable.

Have you tried buying from EBay if you are in USA. Overnight delivery.

Previous generation Oticon and Bernafon had interchangeble chargers. Current generation, Oticon Intent has a specific charger.

For whatever it’s worth, the Philips smart charger seems to work fine with my oticon intents. They fit a bit more snug than the oticon dumb charger – not 100% sure if that’s intentional for the smart charger or if it just reflects the slightly different shape between the oticon and philips aids. I don’t have the oticon branded version of the smart charger to compare.
