Wireless Remote-Control Power Bank Style Audio Jammer

The Au-PB ultrasonic voice recorder jammer is a next-generation device designed to safeguard confidential conversations. Hidden inside a realistic power bank shell, it works as a portable anti-recording tool while remaining unnoticed, even when charging your smartphone.

Key Features of the Au-PB Recording Protection Device

• Ultrasonic Suppression Technology – Blocks microphones on smartphones, wireless and wired recorders within 5 meters radius and up to 300° angle coverage.
• Stealth Power Bank Design – Functions as a charger while acting as a microphone suppressor device, making it discreet and practical.
• Adjustable Interference – Users can fine-tune frequency and strength to maximize effectiveness in different environments.
• Battery Status Display – Real-time monitoring for reliable, uninterrupted operation.
• Ultra-Compact Size – Small enough to avoid suspicion, yet powerful in performance.

Flexible Use Cases

• Business Meetings – Place one jammer directly on the table facing your counterpart, and another under the table or at a different angle for complete coverage.
• In Vehicles – Position one device near the rear window and another on the armrest, targeting hidden microphones from multiple sides.
• Dynamic Environments – Works in offices, cars, cafés, and other sensitive areas. Depending on visibility and microphone type, suppression results may range from full blocking to partial interference.

For the best results, use multiple ultrasonic voice recorder signal blocker from different angles. This setup significantly increases the chance of full recording suppression, especially against high-quality microphones or in complex acoustic environments.

For optimal performance, keep the ultrasonic emitters (marked as No.4 in the diagram) unobstructed.
Avoid placing the jammer too close to your eyes or ears while it is in operation.
