How to Repair a Broken Car Charger?
2 Answers
Check whether there is an issue with the power supply of the charging port, external devices, or charging cables. If the external devices and charging cables are functioning properly. If the fuse of the charging port is damaged, replace it. If both the wiring and fuse are in good condition, it is recommended to go to a repair facility to directly replace the charging port.
When my car charger stops working, I usually start with some simple checks to identify the issue. First, test if the cigarette lighter port is supplying power by using a test light or plugging in another device to see if it works. If there's no power, the fuse might be blown. Locate the car's fuse box, typically found under the driver's seat or in the engine compartment, and check the fuse labeled for the cigarette lighter. If it's blown, replacing it with a new one (a cheap part costing just a few cents) should solve the problem. If the cigarette lighter port has power but the charger still doesn't work, unplug the charger and inspect it for any signs of burning or cracks. Clean the USB port and remove any debris from the cigarette lighter socket. Most car chargers have simple circuits but contain small, fragile components that are prone to damage. Instead of attempting a repair, it's safer and more convenient to replace the charger with a new one—they're affordable, usually costing around ten yuan. If you still can't figure out the issue, the problem might be unstable power supply voltage in the vehicle. In such cases, it's best to visit a professional auto shop for diagnosis to avoid the risks of DIY repairs, such as causing a short circuit.
