Review on TESSAN Power Adapter For USA To Australia, AU, Argentina, And Fiji - Type I Travel Adapter With 4 American Outlets And 3 USB Ports - Australia Power Plug Adaptor For New Zealand And China Travel by Juan Simpson

These worked really well. I bought 3 because we have a family of 5 on the trip. But we only used 2. These have enough plug in spots and USB slots to charge everything we needed.We did not use a hair dryer or curling iron with this because these seemed like adapters not converters so we didn't even try. I had a converter with us for that.Con: is these are only UK so when we traveled in other areas like Spain we could not use this. But we spent most of our trip in the UK. Just be aware the the difference countries have different plugs.
