There is a lot going for buying an inverter made in Australia with a 2 year guarantee as well. T he SEA range starts with a 150 watt model. This is adequete for running a juicer, stab mixer, laptop and most equipment chargers etc. It is a full sine wave model which means the electricity is cleaner than your 240 volt at home and with less variation. A thing NOT in its favour is that it is NOT double isolated. This means that in the event of complete melt down 240 volt cant leak into your 12 volt system. We liked the spunky yellow case with built in fan on this inverter. You don't get a 240 switch on the Piccolo model. It's worth remembering with all inverters to let them turn on and settle down before applying a load. This is particularly important with computers. The all important start wattage is very good at ????? . We didn't like the fitting of a cigarette lighter plug as these from bitter past experience can spell bad news. With a 150 watt inverter starting currents can easily reach 25 amps momentarily - not good! A better way to instal would be to use a two pin polarised plug available from Camec or electrical wholesalers.
