A car converter is a small electronic device designed to convert the DC electrical output from an automotive battery into alternating current, which can be used to power devices such as cell phones and other small devices. Most car inverters or converters (Silux) are designed to fit the cigarette lighter, which is located on the control console in most vehicles and provides easy access to the battery. The inverters in turn are normally connected to charging cables or cables designed for specific devices, especially phones or small computers.
Theoretically, almost any device can be powered by the car battery, but most car converters are intended for small and occasional use only. Powering large devices or using charges for extended periods can drain the battery and affect the power the car itself is receiving, which is not recommended. Larger and more permanent options can be mounted directly on the battery itself and wired into the car, although this often requires a lot of experience and certainly a different cost than a common converter.
Car Power Basics: How the Car Converter Works
The batteries in most cars and trucks provide power to the vehicle, as well as support accessories such as radios and lighting. When the car is in motion, the battery normally charges itself, which allows a more or less constant flow of power into the vehicle. This power looks like a direct current, or “DC”.
Direct current is perfect for devices powered directly from the battery, but does not normally work for external electronics. Things like smartphones and music players normally require alternating current, or “AC”. The main task of the inverter is to convert the DC signal into an AC output.
