High Power 12W Handheld Signal Jammer with Built-in Battery and Cooling System - OEM Available

The 16 Bands Hidden Antenna Signal Jammer is a professional-grade device designed for security applications where signal blocking is required. This advanced jammer features a unique ABS shell design with hidden omnidirectional antennas, providing comprehensive signal blocking capability across multiple frequency bands.

This powerful device effectively blocks all current mobile communication technologies including 5G, 4G LTE, 3G, 2G networks, along with WiFi signals (2.4GHz & 5GHz bands), GPS tracking signals (L1-L5), Lojack, and various RF frequencies (315MHz, 433MHz, 868MHz). The total output power reaches 12W (0.7W per band), with potential to exceed 16W when accounting for antenna gain.

The jammer features an efficient cooling system with aluminum alloy radiators and three built-in cooling fans, maintaining operating temperature below 50°C. The compact handheld design (280x130x46mm) includes a built-in 12000mAh lithium battery providing continuous operation for over 2 hours. Power can be supplied through AC adapter (110-240V) or 12V car charger.

Key applications include government facilities, conference rooms, theaters, examination centers, prisons, military installations, and other sensitive areas requiring signal blocking for security or confidentiality purposes. The device comes with DIP switches allowing selective activation of specific frequency bands without affecting others.

Each unit undergoes strict quality control and frequency testing before shipment. The product carries ISO 9001 & 14001 certifications and comes with 1-year warranty. OEM customization is available for both hardware specifications and branding requirements.
