model: 500W 12V - 240V

Inverters convert the energy stored in one or more batteries into a consistant
230 V or 110 V AC voltage. Unlike generators there is no noise, no
fuel requirement making them ideal for use in confined areas. Inverters
are an ideal power source for Rubbercut Regroovers, work lights and
power tools. In order to determine the model required you should check
the output of an appliance (Watts), then correlate this to an Inverter
capable of giving you the equivelent or more continuous power output.
