What is the power supply voltage allowed by the car locator.4G GPS Tracker

　　1, the ordinary car battery voltage is 12V, so the vehicle power supply system is 12V for the standard design work, considering that the voltage impact after the car starts high-speed operation will exceed the battery voltage, generally reaching 16~18V, and even some battery aging peak voltage can not be absorbed, the voltage is more than 20V. Therefore, the pressure resistance of the car electronic system can generally work below 24V, and 24V can also be not damaged for a short time. 2, the truck system because the battery is 24V, so the vehicle power supply system is on a level. Also taking into account the impact voltage problem, electronic circuit design is generally up to 40V grade. For the above reasons, if the product design specifically indicates the voltage requirements, the general price is cheaper and can only be used on the car. If not specified, it is a universal system, which can be used in trucks or cars. Usually GPS is equipped with a power supply, plugged into the cigarette lighter interface (OBD interface), that power can generally be 40V. If there is no power supply then 12V to 24V.
