The EM 4500 offers the user a high output, quiet generator with a long running time. Featuring a large 17 litre fuel tank, running on unleaded petrol, this model will provide 4000 watts of power for 6.8 hours before requiring a re-fill. A fuel gauge and volt meter are fitted to monitor the generator without the need to switch it off. Dual voltage output, 115 / 230 volts, is ideal for running 110 volt power tools or standard 240 volt appliances. The EM4500 provides cleaner electricity than the mains due to its automatic voltage regulator.
