The unit is powered by a 9V battery which will last for hundreds of hours. It is housed in a slim custom case that will slip right into the pilot pocket in your airplane.

The battery SafetyCell will work with any headset, in or out of the airplane. If you want to use your SafetyCell on your boat, lawn mower, truck or airplane, this is the unit for you.

This unit is amplified and is about twice as loud as the amplified SafetyCell. It will work with any cell or satellite phone that has the standard 2.5mm earpiece jack for handsfree use. Phones that do not have this feature will require an adapter. This unit now has a separate input jack for your mp3 player or walkman.
