The Electric Optics Small EL Wire Inverter is one of our smallest inverters, and perfect for applications that require a small amount of wire, but where the inverter needs to be hidden. It takes up virtually no space at all, and provides power to a small amount of wire (up to 3 Feet). 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 an exposed positive and negative lead wire, which will hook up to your power source. This unit does NOT come with its own power source.
