Wiring up our 120/240 VAC isolation trasnformer for use at the campground. We donated it to the owners so that people from 220 VAC countries, such as Europeans, would have a source of power while at the campground. We had made essentially zero use of it in 14 months and wanted to jettison the 70 pounds / 32 kilos. Rincon del Viajero. Otavalo, Ecuador.
