Reasons why a car phone charger cannot charge the phone are as follows: 1. The car charger is incompatible, and the phone cannot be charged. 2. Incomplete compatibility results in a smaller charging current. 3. Poor quality of the car charger leads to a small output current, making the charging effect insignificant, giving the impression that the phone is not charging. Below are some precautions: 1. Do not use the car charger in a humid environment. 2. Do not store the car charger in a damp environment. 3. The suitable operating temperature range is 0-45℃. 4. Keep away from children. 5. Avoid lightning strikes. 6. Unplug the charger promptly after charging is complete.
I often encounter charging failures in my car, and experience tells me the most common issues are poor contact or charger malfunctions. First, make sure the charger is fully inserted into the cigarette lighter socket; sometimes bumpy roads can cause it to loosen and disconnect by just a fraction of a centimeter. The cigarette lighter socket itself may be clogged with ash or rust—just clean it with a thin stick. If the light doesn't turn on, the charger is likely burnt out—unstable car voltage, especially during engine startup, can damage low-quality chargers with voltage surges. It's recommended to buy branded chargers with protective chips. USB cables are also frequent culprits; aging, broken, or bent connectors can cause poor contact, and replacing the cable often helps. Another reason could be a blown fuse in the car's cigarette lighter circuit, located in a small box under the dashboard—usually 15A, and replacing it is very inexpensive. Don’t forget the phone side; the charging port might be clogged with dust or have safety settings restricting charging—cleaning or restarting the device can solve this. Develop a habit of securely plugging and unplugging, and keep foreign objects out of the ports to avoid many headaches.
