The user in focus

Traveling audiologists will know the struggle of instruments running out of power and the challenge of accessing an alternative power supply.

Being with limited power supply cannot only bring the work of a travelling audiologist to a stand-still but also make the entire journey and intention of the testing redundant. Our portable power bank is powered by 4 AA batteries. Fully charged, this power bank will power your equipment for 2 hrs.
