Review on 🔌 DOACE 2000W Travel Adapter Converter - All In One Combo with Dual USB, Step Down Voltage 220V to 110V for Hair Dryer, Straightener, Curling Iron, Laptop, Camera, Cell Phone - US to EU/AU/UK Plug - Compatible with Over 190 Countries by Robert Arneson

This device uses a standard US two-pin plug that folds into the device. You'll need to connect the device to one of the country-specific adapters, which (obviously) plugs into an outlet. This means that the device protrudes a few centimeters from the wall. This can cause the device to sag. This was very noticeable when the MacBook charger was connected to the device, although the contact was sufficient to power the charger. There were times when the hair dryer seemed to be running at less power than usual. Not sure if it was the converter or the Irish power supply. It's nice to be able to use it as an adapter, converter and USB charger all in one package. The two USB sockets have a total output of 2.1 A, so it takes longer to charge two devices at the same time. Overall he did what we needed.
