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 checking, it was found that the fuse of the original cigarette lighter 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 is still bad.

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.

Simple judgment and solution:

Car owners can first observe which kind of interface their GPS vehicle power supply belongs to. When the long plug is hot plugged, the fuse will burn, while the short plug will not. The owner can replace the on-board power supply of the short plug.
