The Mistake 8 Out of 10 Drivers Make That Could Be Costly - What You Should Never Plug Into Your Car

Modern cars are increasingly connected, offering conveniences like wireless charging. However, using traditional USB ports to charge high-power devices like tablets and laptops can cause problems. These car USB ports are not designed to support such devices, leading to interference with the infotainment system, circuit overload, or port damage. The power difference is significant: a USB 2.0 delivers 5V/0.5A, while a USB 3.0 reaches 0.9A, compared to fast charging technologies that can reach 20V/5A. Experts recommend using a certified fast-charging cigarette lighter adapter instead of directly connecting to the car's USB port, and avoiding low-quality USB multipliers.
