They only transform the plugs from the EU shape to the US shape. As the voltage in Europe is over 220V, it may destroy your 110V appliance. Please make sure your appliance (hairdryer/ straightener/ hair curler/ electric toothbrush/ razor etc.) is dual voltage compatible (110-220V). If your device supports 110V input only, please don't use them in Europe, or prepare a voltage converter to step down from 220v to 110v. ?One Adapter Replaces 3 Chargers?The US to EU plug adapter combines 2 USB ports (Max 2.5A) & one standard N American 2 or 3 prongs outlet (Max 250V/10A) together, allowing you to charge 3 electronics simultaneously, such as iPhone, iPad, Power Bank, Camera, Earbuds, Kindle, Laptop and more.
