I am editing my review after using it this summer. It works great, however I had trouble using a brand new Duracell micro usb to charge my android device. It worked on another converter. I also tried the charging cable when arriving back in the states, and it didn’t work well. There were times the adapter needed to be turned upside down to charge. I had no problem charging, and it works great. It just might be the cable and outlet that can give this adapter 4.5 stars. For what it’s worth and compared to what I’ve had is really good, especially having usb slots also to charge. You can charge three at same time, but I’d recommend only two. I recommend you try it.
