Review on 🔌 BESTEK 250W Power Converter: Universal Travel Voltage Transformer with 3-Outlet, 4-Port USB & Multiple Plug Adapters - 220V to 110V by Joshua Coulter

Overall a great product. Used it every day on a 10 day trip to Ireland to charge cellphone and camera batteries and smaller gadgets. The extension works well and you can use the detachable wall plug directly on devices/battery compatible with 230V/50Hz. My only complaint is that the device's fan is a bit noisy, especially when placed on a hard desk that's at ear level in bed. While it's not unbearable, it's definitely noticeable, especially if you have to keep the device close to you overnight. I mitigated this somewhat by placing the device on the floor, being careful not to block the vents.
