This item was bought in Australia through amazon.com.au. Behind the scenes it was shipped from US, I assume, to amazon in Australia and the delivered to me from Amazon in Australia. After unpacking, I discovered that power supply had American power plug/interface. I had to go out to get an adapter. I watched a video on YouTube where someone ordered the same product in UK and, when he unpacked the product, I observed that he was supplied an American interface power to UK power adapter within the box. I am confused as to why my box did not have a power adapter??? The WD 8TB drive works well otherwise and I have absolutely no complaints with the product.
