What is the reason why the rear USB of the Baojun 730 cannot charge?

[VonPhoebe]

The rear USB of the Baojun 730 may not be able to charge due to a blown fuse, which can be resolved by replacing the fuse. Alternatively, it could be because the tail plug is incompatible. The USB interface in a car primarily utilizes the vehicle's standard power supply to charge electrical devices via USB or serve as a fixed power interface for electrical equipment. The USB interface is a type of vehicle transmission line, known for its fast transmission speed, ease of use, support for hot-plugging, flexible connection, and independent power supply. It is typically a universal interface for USB devices such as flash drives and MP3 players. The Baojun 730 has body dimensions of 4710mm in length, 1780mm in width, and 1740mm in height, with a wheelbase of 2750mm. The 2019 Baojun 730 CVT version comes standard with an 8-inch floating central control multimedia screen, equipped with functions like Carplay and the SSPLINK in-car connectivity platform, which supports both Android and Apple systems simultaneously.

In my experience with the Baojun 730's rear USB not charging issue, the most common cause is a faulty USB port itself. Repeatedly plugging and unplugging phone charging cables can loosen the connection or cause internal contact oxidation/breakage. Also, check the fuse—Baojun's fuse box is usually located below the steering wheel on the left side, labeled 'Power Outlet.' If the 5A fuse is blown, simply replacing it should solve the problem. Wiring issues could also be the culprit, such as aging or broken wiring from the head unit to the rear harness. Use a multimeter to check if the power supply voltage is a normal 12V. I recommend also inspecting other points, like whether the cigarette lighter works—if not, it might indicate a full-vehicle electrical issue. USB charging is part of the low-voltage system, so avoid using off-brand chargers to prevent overload. Clean port dust yourself if needed. Generally, try simple fixes first; if that doesn’t work, seek professional inspection for safety.

My Baojun 730's rear USB sometimes doesn't charge, which is quite a headache. Start with the simplest solution: try a new USB cable to rule out cable or phone issues. If the port is dirty, use a soft brush to remove dust and debris. Next, check the fuse—refer to the owner's manual for the fuse box location, and replace the mini fuse if it's blown. Turn off the engine before replacing to avoid electric shock. If fuses keep blowing, it might be due to a short circuit, like damaged wiring causing overload, so inspect for loose wire harness connections. Finally, ensure the vehicle battery and alternator are supplying power properly. For prevention, regularly maintain and clean electrical connectors, and avoid plugging in during humid weather. Minor issues are easy to fix—no need to rush to the repair shop and spend money.

I also encountered the issue of the USB port in the rear row of the Baojun 730 not charging. During a family trip, the phone wouldn't respond when plugged in, and trying different devices didn't help. Later, I found out through self-inspection that it was either due to poor port contact or a blown fuse. I searched for tutorials online, opened the fuse box, and replaced the fuse to fix the problem. It's important to avoid rough plugging and unplugging in daily use to extend the lifespan. USB ports in budget cars are prone to issues, but they can usually be fixed with low-cost solutions.

As a car owner who frequently travels with children, the non-charging rear USB in the Baojun 730 is quite frustrating. The issue is often related to a blown fuse, which protects the circuit from overload; otherwise, it could lead to significant overheating hazards. The fuse is located under the dashboard—check by touch to see if it's blown and replace it promptly. Port oxidation or loose wiring can also cause failure, but avoid disassembling it yourself to prevent risks. USB charging is part of the vehicle's low-voltage system, but negligence can easily cause short circuits, affecting safety. Prevention is key: keep it dry and clean, prioritizing internal components.

When troubleshooting the rear USB failure in the Baojun 730, I consider the issue holistically. First, clean any foreign objects obstructing the port and retest; if ineffective, check and replace the corresponding fuse in the fuse box. For wiring issues like loose connection points, inspect and tighten them; rarely, a control module malfunction may occur but can be resolved with a system reset. For prevention, clean electrical components quarterly to avoid oxidation and ensure stable 12V power supply. It's cost-effective to remind technicians to inspect during maintenance.
