There are many power supply methods for network jammers. First, they are classified according to the size of the radio frequency transmission power. The network jammers in different categories and their power supply methods are roughly as follows:

1. High-power network jammer (transmitting power greater than 50W): usually AC direct power supply is used. Because the power consumption of such products is very large, the use of AC power supply can provide sufficient power to the equipment;
2. Medium-power network jammers (transmitting power greater than 2-20W): most of them use AC power supply, and a small part use DC power supply or AC and DC switchable power supply;
3. Low-power network jammers (transmitting power less than 2W): Most of these products are handheld or concealed network jammers. These products are mainly powered by DC, and they are mainly used to charge batteries when powered by AC. Some models can be used while charging.
Low-power network jammers usually consume less than 200W of electricity due to their low transmit power. Therefore, some customers also use them in cars and use the cigarette lighter interface on the vehicle to supply power. It must be noted here that the total power output by the car cigarette lighter is limited. Once the power is overloaded, it may cause damage to the vehicle power line.
