Why can't the cigarette lighter in Kia K5 charge?
3 Answers
The reason why the cigarette lighter in Kia K5 cannot charge is: the cigarette lighter is an external USB interface and cannot provide charging. Taking the 2020 Kia K5 K5 as an example, its body dimensions are: length 4980mm, width 1860mm, height 1445mm, wheelbase 2900mm, fuel tank capacity 60l, and body structure is a 4-door 5-seater sedan. The 2020 Kia K5 K5 is equipped with a 1.5T turbocharged engine, with a maximum horsepower of 170ps, maximum power of 125kw, maximum torque of 253 Nm, and is matched with a 7-speed dual-clutch transmission.
I've been driving my Kia K5 for over two years when suddenly last week the cigarette lighter stopped charging my phone, which was really frustrating. I tried several different chargers and devices, but none worked—either the light didn't come on when plugged in or it just wouldn't charge. After checking online, it seemed most likely that the fuse had blown, as the cigarette lighter circuit is prone to this issue. The Kia K5's fuse box is under a small cover near the driver's footwell. I located the 15A fuse for the cigarette lighter, pulled it out with small pliers, and sure enough, it was blackened and melted. I bought a new fuse for two bucks at the auto parts market, replaced it, and everything went back to normal immediately. I suspect it was caused by an overload from using a knockoff charger, so now I only use genuine ones to avoid similar problems. Also, if the socket's spring contacts become loose, they can cause poor connections, so be gentle when plugging and unplugging. Regularly checking the fuse box can save you a lot of trouble.
The most common reason for a cigarette lighter not charging is a blown fuse, especially in models like the Kia K5. I've encountered this issue several times. First, confirm that the charger itself isn't faulty. If other devices also don't work when plugged in, check the fuse box. In most car designs, the cigarette lighter fuse is located under a small cover on the left side of the driver's seat, and the 15A fuse is prone to blowing—simply replace it with a new one to test. If that doesn't solve the problem, the issue might be internal aging or deformation of the socket, or a broken circuit caused by loose or corroded wiring connections. If you're comfortable DIY-ing, use a multimeter to check the voltage—no reading indicates a circuit fault, and it's best to visit a repair shop promptly to prevent potential overheating or fire hazards. Additionally, avoid using high-power car chargers to prevent overload, as simple maintenance can extend the lifespan of your cigarette lighter.
