Promising review: “I bought this adapter some three months ago and it worked perfectly in Vietnam, Cambodia, Bahrain, Oman, and Italy (where I saw two different outlet types). My phone is at the stage where it needs to be charged once or twice per day. This is my ‘need to pack item’ when traveling. I also like the fact that it has USB outlets because I often have to charge my phone and something else at the same time. By the way, it also worked well in the Delta One cabin and in the ANA All Nippon Business cabin. This is also what I use for charging my phone, iPod, and smartwatch using the USB connections right here at home in the US.” —Mark, WV
