The Importance of High-Power Portable Signal Jammers in Special Applications

In certain special scenarios, high-power portable signal jammers have gained popularity among users. These scenarios include hostage negotiations involving special police forces, emergency situations requiring immediate communication control, and the discovery of suspicious explosive devices in crowded areas. In such cases, it is essential to rely on professional equipment to provide technical support. Typically, these jamming devices use built-in batteries as their power source. However, a crucial question arises: can these high-power portable signal jammers work continuously for more than three hours if the problem-solving process is unexpectedly prolonged?

Power Requirements:

According to the technical specifications provided by mainstream manufacturers of high-power portable signal jammers, devices with a nominal radio frequency (RF) transmission power of 50W or above, and with 15 or more RF modules (or frequency bands) can be considered as practical high-power full-band signal jammers. A preliminary assessment suggests that such a set of full-band signal jammers usually has a combined output power of RF modules ranging from 600W to 1000W. Considering the conventional conversion ratio of RF power to power consumption (1:3), the total power consumption of these devices is estimated to be around 2000-3000W.

Battery Capacity:

Those familiar with battery energy consumption can deduce that supplying power to a device consuming 2000-3000W requires a significantly large battery capacity. If we consider the power supply to be provided by batteries, the capacity must be substantial. For instance, if we assume a power consumption of 2000W, and the battery’s output voltage is 24V, a high-power portable signal jammer, as a load, would require a battery capacity of 250Ah to meet the requirement of continuous operation for three hours.


In conclusion, high-power portable signal jammers play a crucial role in various special applications, such as hostage negotiations, emergency communication control, and the detection of suspicious explosive devices in crowded areas. These devices typically rely on built-in batteries as their power source. However, due to their high power consumption, it is essential to ensure that the battery capacity is sufficient to support continuous operation for extended periods. As technology advances, manufacturers continue to improve the efficiency and capacity of batteries, enabling these high-power portable signal jammers to meet the demands of real-world scenarios effectively.
