Review on 💡 Ceptics PU-200X Voltage Converter: The Ultimate Travel Adapter for Hair Styling Tools, Chargers, and More - Step Down Power Plug with 4 USB Charging Ports - Convert 220V to 110V - EU/AU/UK/US Compatibility Included by Ricardo Stewart

Works perfectly. We are in Germany now. Laptop charger, hair straightener, USB, my cpap, everything works and charges great. Of course, you'll need to make sure you don't plug in too much to exceed the 230W maximum power output. My laptop charger uses 185W, so I don't plug it in at the same time as another AC device. You can pretty much leave USB devices plugged in while using any AC device. He's also very quiet. The only time I hear the fan quietly is when my laptop's charger is pulling a lot of load out of the unit. Comes with several different wall adapters and a nice travel bag for everything. money well spent.
