rate: 100I think it's convenient when you travel.
It is a thing to think that the usb port was always lacking while preparing for a trip to Japan. It works well without defect. Just 220v zenders do not feel right when you put them in the holes, but they are a bit loose and shake slightly up and down. There is no problem to use it and it will not be a problem if the original purpose is to travel to Japan. I bought it cheaply ^ ^Jul 09, 2018
