Hi Peter, If you are going to make an adapter cord, Willie's approach makes sense. Put 220V plug on your charger and then make a 110V plug to 220V socket adapter cord. This makes sense for two reasons. First, fewer people are trying to plug in 220V things than 110V. Second, a 220V appliance plugged into 110V probably won't fry where a 110V appliance plugged into 220V accidentally, probably will.
