The P-US-012-5 Portable 12-Band Jammer is designed for users who need reliable, on-the-go signal control-whether that means protecting conversations, securing a work environment, or reducing unwanted digital tracking. Despite its compact size, it covers an impressive range of 12 different frequency bands, giving you multi-layer protection in one handheld device.
Unlike bulky desktop blockers, this portable cell jammer unit is purpose-built for mobility. Slip it into a bag, keep it in your car, or carry it between meeting rooms-it stays ready whenever you need quiet, private space without digital interruptions.
A Small Device With Full-Spectrum Protection
Covering frequencies from 315 MHz to 5850 MHz, this jammer blocks nearly all common wireless technologies used for communication or tracking, including:
- Cellular networks: GSM, CDMA, DCS, PCS, 3G, and 4G LTE (except 5G)
- WiFi & Bluetooth: 2.4 GHz / 5.2 GHz / 5.8 GHz
- GPS L1: Prevents satellite-based positioning
- RF remote controls: 315 / 433 / 868 MHz
Whether you are preventing location tracking, blocking short-range wireless links, or creating a secure no-signal zone, this 12-band design ensures comprehensive coverage.
Smart Control With DIP Switches
Each frequency band can be activated independently using the built-in DIP switch system, letting you disable only the signals you choose. This makes the P-US-012-5 ideal for customized scenarios such as:
- Allowing WiFi but blocking all cellular signals
- Blocking GPS only while keeping mobile data active
- Creating a full “dead zone” for all wireless communication
Flexible control = safer, smarter jamming.
Impressive Jam Radius in a Portable Design
With up to 10W total output power and professional-grade antennas, the jammer can create an effective protection sphere of 5-20 meters, depending on environmental signal strength.
Its rugged design, consistent performance, and stable heat dissipation make it a reliable tool for:
- Business meetings & confidential discussions
- Personal privacy protection on the go
- Vehicles (car charger included)
- Anti-tracking and anti-surveillance use cases
- Secure rooms, offices, small workshops
Designed for Real-World Mobility
The P-US-012-5 comes with both AC and DC power supplies, allowing continuous operation indoors or in a vehicle. When used in a car, it prevents GPS-based tracking and ensures communication privacy during travel.
