Lots of electricity... has to flow when you're a Griswoldian. But it's much more subtle in the USA than it is here. It would therefore be anything but smart to use American products with plugs without a voltage converter. The solution comes here. Our converter is ideal for the Advent house, the fairy lights and other smaller devices from the USA. Please always note the wattage. Scope of delivery: 1 original Moose Mug light chain with 10 Moose Mugs Material: plastic, metal Dimensions: 1.5 meter cable feed Connection USA / DE plug Info: Converts 230 V to 12 V, maximum output 100 watts, CE seal.
