This is a convenient travel adapter for overseas trips and business trips. It has two USB charging ports, so you can charge smartphones and other devices simultaneously. [Color] Blue Green [Other] USB 2.1A 5V output compatible I purchased this last year and used it a few times, but there are no noticeable scratches or stains. There is no instruction manual. The case in the photo is included. This item has been stored at home, so I would appreciate it if you could purchase it if you understand this. Immediate purchase is welcome! Thank you.
