N12P - 12 Bands Ultra Powerful Multiband portable 5G Cell Jammer (37W)

The N12P is a professional-grade, high-power portable Jammer blocker engineered for environments where information control and privacy protection are critical. Designed to outperform standard devices, it delivers broad-spectrum signal blocking across up to 45 communication standards, covering both traditional and next-generation wireless technologies.

The device supports modern networks such as 5G and 4G LTE, along with Wi-Fi (2.4 GHz & 5 GHz), GPS/GLONASS, UHF/VHF radios, and LOJACK systems. With a total output power of 37 W, it effectively disrupts signals from mobile phones, tablets, trackers, and concealed transmitters within a coverage area of up to 40 meters, depending on surrounding conditions.

The N12P delivers more than three times the output power of common 12-antenna portable jammers on the market, such as the PJ-123 or PJ-12S, which typically offer only about 12W. Its jamming range is highly effective and sufficient for everyday use. Built with a lightweight aluminum alloy housing and equipped with the latest high-gain antennas, it provides reliable performance. If your needs are limited to blocking common mobile phone signal, GPS, WiFi, and low-frequency signals, the N12P is the most suitable choice.

Built for High-Interference Environments

Unlike entry-level Cell phone jammers, the N12P is developed for demanding signal conditions, including areas close to cellular base stations. In addition to cellular suppression, it disables satellite navigation signals, preventing location tracking via GPS devices. Support for higher Wi-Fi frequencies allows it to neutralize even high-speed wireless networks.

A professional cooling architecture, combining three internal fans with an aluminum heat sink, ensures stable operation at full power for up to 70 minutes without performance loss due to overheating.
