Hello to everyone, my name is William and I'm new at this forum. I have a simple question: I live in the US (110-120V (60 Hz) and I'm traveling to Europe next month. I'm taking my XT5 with me and I would like to know if I can connect a BC-W235 battery charger to the wall outlet in my hotel room just by using a simple plug adapter or do I need to purchase a 220-240V (50 Hz) voltage converter? Thank you in advance for your response.
