If the GPS jammer is a built-in battery type, it cannot be used while charging, it is easy to damage the device, and it is best not to charge the electrical appliance during use, just like our mobile phone, it is best not to use it while charging. If you The GPS jammer is a direct current (dc) device, you need to plug it into an available power source, and that's it. It can also be used without a built-in battery, such as a car GPS jammer, which needs to be plugged into the car's cigarette socket for normal use.
