Power Supply & Battery
AC Power Supply: Universal voltage support (110-240V AC, 50-60Hz) with a dedicated AC charger, converting to 12V DC for the jammer.
Car Power Supply: Equipped with a 12V DC car charger, enabling use in vehicles (e.g., trains, buses) for on-the-go security.
Built-in Battery: 7.4V/12000mAh high-capacity rechargeable battery, supporting approximately 80 minutes of continuous operation.
Note: The jammer supports simultaneous charging and use, but frequent long-term use (over 3 hours) in this mode is not recommended to extend battery life.
Physical & Cooling Specifications
Antennas: 27 high-gain omni antennas (192mm in length, 1-3dBi gain) for strong signal reception and jamming coverage.
Cooling System: High-efficiency aluminum alloy radiator + 4 built-in cooling fans, ensuring rapid heat dissipation even during prolonged use (prevents overheating and extends device lifespan).
Dimensions:
Jammer host (without antennas): 210×133×85mm
Neutral packing size: 295×260×125mm (gross weight: 4.0kg)
Safe carry case size: 345×335×145mm (gross weight: 6.0kg, for secure transportation and storage)
User-Friendly Features
DIP Switch Control: Allows independent on/off operation of any signal band without affecting other bands-flexible for customizing jamming needs (e.g., blocking only mobile signals while keeping Wi-Fi active).
LCD Battery Display: Real-time monitoring of battery status, including capacity percentage, working voltage, and current-ensures users stay informed about power levels.
Handheld & Portable Design: Weighing only 3.0kg (host), the jammer is easy to carry; the optional safe case provides added protection for outdoor or mobile use.
Advantages
Comprehensive 28-Band Portable Jammer: Exclusive design covering FM radio and Wi-Fi 6E (a cutting-edge feature for blocking latest Wi-Fi standards), plus all generations of mobile networks (2G/3G/4G/5G), GPS (L1-L5), LORA, LOJACK, UHF/VHF, and RF signals (315/433/868/915MHz).
Powerful Jamming Performance: 28W total output power (1W per band) delivers a jamming radius of 2-25 meters (tested at -75dBm), ensuring comprehensive coverage in small to medium-sized spaces.
Reliable Cooling: The combination of an aluminum alloy radiator and 4 cooling fans prevents overheating, making the jammer suitable for long-duration use (e.g., all-day meetings, training sessions).
