The Eagle Creek Dual Wattage International Converter Set allows you to use North American appliances internationally. The set includes the actual converter as well as five ungrounded adapter plugs you'll need in order to make use of foreign outlets. The converter has a dual circuit unit that operates as a 0-25 watt transformer in the low setting and a 26-1875 watt converter in the high setting. Use the low setting with battery chargers, curling irons, shavers, tooth brushes, and other electric appliances between 0-25 watts. Use in the high setting with hair dryers, irons, heating pads, coffee makers, and other appliances between 26-1875 watts. You'll have to manually change the wattage depending on what you're using. Do not use your computer with any Eagle Creek transformer or converter.
