This new, Voice-Activated cellphone powerbank looks and functions like an ordinary portable cellphone charger. Secretly, this charger conceals hidden a microphone. Hang on a lanyard or slip into a pocket for discreet recording, or use the included magnet to magnetize it somewhere out of sight. Use this unit at the office, school, to covertly record voice as a secret shopper or investigator, or to simply record notes and interviews at school or work.
Voice-activation mode. The voice-activation feature allows you to avoid long hours of silent recording and save battery life. This unit can be on standby for up to 150 days waiting to pick up any voices you may hear.
