How long should the battery power supply time of the portable mobile phone signal shielding instrument be?
The so-called portable cell phone signal jammer is mainly reflected in its small appearance and small size, which is easy to carry or quickly transfer. Another obvious functional feature is the diversity of power supply methods. In addition to the most basic AC power supply method, it usually also has a built-in large-capacity rechargeable battery. In some wild places or working environments where AC power supply cannot be obtained, The built-in battery can be preferentially used for power supply. Then the question comes out: how long should the battery power supply time of the portable mobile phone signal shielding instrument be?
The first thing to understand is that as long as it is a portable mobile phone signal jammer used in an outdoor environment, it is generally a high-power model. High power refers to the RF power value of the output port of the signal shielding module in the device, and the RF power is greater than 30W. Basically, they all belong to the category of high power. Since the radio frequency power is very large, the corresponding power consumption will also be very large. The ratio of radio frequency power to power consumption is about 1:2 or 1:3. It can be seen that the power consumption of a high-power signal shielding module is about 100W.
The total power consumption of a portable mobile phone signal shielding instrument depends on how many signal shielding modules the mobile phone signal shielding instrument is equipped with, and each signal shielding module corresponds to a different frequency range. Let's take the mobile phone signal as an example, or it is necessary to completely interfere with all 2G, 3G, 4G, 5G signals in the mobile phone signal, as well as WI-FI2.4G, WI-FI5.8G, and at least 12 signal shields need to be configured Module, so it can be calculated that the total power consumption of this portable mobile phone signal shielding instrument for all mobile phone signals is about 1200W, that is, the power consumption of this device for 1 hour is 1.2 degrees.
Back to the question raised at the beginning: how long should the battery power supply time of the portable mobile phone signal shielding instrument be? Some customers often answer directly: Of course, the longer the better! Can it be battery powered for half a day (6 hours or 12 hours)? The answer that is more in line with the actual situation is: Considering that the increase in battery capacity will inevitably increase the weight of the battery itself, it will also increase the space occupied by the battery. When these two factors are superimposed repeatedly, it will inevitably affect the mobile phone signal shielding instrument. The most important "portable" functional attribute? The expedient result after the final comprehensive consideration is: within the acceptable range of weight and size, the optional built-in rechargeable battery, the power value is in the range of 1000W-2000W, converted into effective power supply time, that is, it can allow The portable mobile phone signal shielding instrument works continuously for 1-2 hours.
