Is it feasible to use the vehicle cigarette lighter to power the mobile phone shielding device?

Customers often ask whether the car cigarette lighter can be used to directly power the mobile phone signal blocker. This question needs to be considered from the following perspectives:

First, determine the purpose of the mobile phone signal blocker. Is it used to block the signal inside the car or outside the car? If it is to block the signal outside the car, a high-power mobile phone signal blocker is required. High power refers to a device with an output power of at least tens of watts in each frequency band. Since the outside of the car is an outdoor environment, the mobile phone signals emitted by base stations along the way or surrounding base stations are often strong. In order to effectively suppress outdoor signals, a high-power signal blocker with sufficient strength is required. If you only want to block the signal inside the car, you can choose a low-power signal blocker. The best-selling wifi jammers and GPS jammers in recent years.

After clarifying the application scenarios and the choice of high power and low power, let’s analyze whether the car cigarette lighter can provide the necessary power for the device. High-power models generally consume hundreds to thousands of watts of power and usually require AC power supply. In this case, the power supply of the vehicle cigarette lighter is not enough. The power line diameter of the cigarette lighter is limited, and the output power is generally not high, generally around two or three hundred watts, while the low-power mobile phone signal blocker generally consumes about one or two hundred watts, which is similar to the output power of the cigarette lighter.

It should be noted that ordinary cell phone signal jammers generally require AC power, and a suitable DC-to-AC inverter needs to be equipped for the cigarette lighter. Due to the limited space in the vehicle driving area, when powering the cell phone signal jammer, whether it is signal shielding inside or outside the vehicle, the safe use of the equipment must be the primary consideration. Ensuring that the inverter is reliably connected to the cigarette lighter and that the cell phone signal jammer is securely placed or installed in the vehicle to prevent any vibration is essential to avoid potential hazards to driving safety.
