Unable to use on-board power supply

Problem 1: GPS cannot use vehicle power supply

GPS cannot use vehicle power

In general, the endurance of GPS is about 1-2 hours, so when driving for a long distance, the on-board power supply needs to be used. However, some car owners find that the warning light is always off when the vehicle power is used. After inspection, it was found that the fuse of the cigarette lighter had burned out, so the external power supply could not be used. At this time, car owners often think that the quality of GPS on-board power supply is too poor, but after many replacement, the situation remains the same.

In fact, the reason why GPs cannot use vehicle power supply is not entirely due to the quality of vehicle power supply, but partly due to the design of cigarette lighter.

Brief discrimination and solutions:

Car owners can first investigate which interface of their GPS on-board power supply belongs to the one shown in the figure below. A plug will burn a fuse during hot plug, while B plug will not. The owner can replace the on-board power supply of model B plug.

GPS cannot use vehicle power

For car owners who use the on-board plug of model a interface, if they do not want to replace the on-board power supply, they can plug it in after starting the car and before flameout to prevent instantaneous high-voltage incineration. If you think this method is troublesome, the owner can choose to make a simple transformation of the cigarette lighter in the car. Fold the metal sheet above the jack of the cigarette lighter flat (at the red mark), so as to solve the problem that GPs can not use the on-board power supply.
