The Phonak Power Pack is a portable battery accessory designed to extend the charging capability of your Phonak Combi Charger Case while away from a wall outlet. It attaches directly to the bottom of the Phonak Combi Charger Case (sold separately) and provides enough power for up to 7 full charges of a pair of Phonak rechargeable hearing aids, making it ideal for travel or situations with limited access to power.

The Power Pack contains a built-in lithium polymer (li-polymer) battery that charges simultaneously with your hearing aids when clipped onto the Combi Charger Case. It is compatible with Phonak hearing aids in the Belong, Marvel, and Paradise product families. Once fully charged, the Power Pack enables up to 7 days of on-the-go hearing aid charging without needing a power cable.
