A converter is essentially a device to change alternating current (AC) to direct current (DC). We have inverters that can change 12 volts to 230 volts, which is handy when you want to charge your laptop for example, using the cigarette lighter in your car. Some power converters are equipped with a USB port for smartphones as well as a regular power socket. Have a look at our Cables and accessories, which include Cable Tools & Connecting Tools and Audio Analysers & Sound Meters.
