Electric Optics Baby EL Wire Inverter is our smallest inverter. It takes up virtually no space at all, and provides power to a small amount of wire (up to 1 Foot). This 12V DC inverter can be used when you have a 12 Volt source already, such as a car battery, or a 2 Prong Wall Unit. Unit will come with a Male Connection, ready to attach an Easy Female Connector to. The female connector is commonly soldered on the ends of EL Wire. Also included is a positive and negative lead wire, which will hook up to your power source. This unit does NOT come with its own power source.
