These converters are the lightest and smallest Power Converters available in the market. Their biggest strength is the fact that they can be placed into nearly any small purse or carry-on luggage bag. These are all Light-Duty Power Converters, which means they should not be used for more than 10-15 minutes at a time. This is the biggest difference between these small converters and other, Heavy-Duty converters. Many customers choose these converters to operate their small electronics and small hair care appliances.
