Acoustic eavesdropper jammer in powerbank AZ-351 - discreet noise generator for the office

The AZ-351 powerbank noise generator is an innovative device that combines the function of a portable charger with ultrasonic eavesdropping interference technology. It is the ideal solution for offices, meeting rooms and other premises where complete discretion and privacy are extremely important.

Noise generator in a powerbank

The AZ-351 acoustic power bank eavesdropper jammer uses advanced ultrasonic electronic jamming technology. The device effectively blocks all recording devices, including mobile phones, voice recorders and other portable audio recorders. This technology works within a radius of up to 1 metre, eliminating the risk of unauthorised recording and leaking of conversations and negotiations.

Discreet and camouflaged

The solution is exceptionally discreet as the device looks and functions like a classic power bank. It is therefore ideal for use during conversations and meetings in all circumstances, minimising the risk of detection. It can charge mobile devices via two USB-A ports while simultaneously blocking audio recording.

Completely safe for users

The noise generator in the AZ-351 power bank uses ultrasound technology, which is completely inaudible to the human ear and free of electromagnetic radiation. It is a safe solution for health that effectively disrupts microphones without damaging the equipment.

High battery capacity

The device is equipped with a 15,000 mAh (3.7V) lithium polymer battery, which ensures long-lasting operation. Thanks to its large capacity, it can act as a power bank, charging mobile devices anywhere. Its compact dimensions (171 mm x 82 mm x 45 mm) and weight of 700 g make it easy to transport.

Extremely easy to use

The AZ-351 is easy to use – it is activated by a touch button or automatically when connected to a telephone. An LED indicates that it is ready for use. Made of high-quality materials in elegant black, it will work in any office or business environment.
