I have an iPhone power adapter from USA and that does not fit into it, because the distance of the slots in the adapter about a mm is too wide. Result: if I poke the US-plug, the contacts of my plug power supply, turn apart, of course, the connector but does not go then purely up to the stop. Means the contacts remain about 2mm visible blank and touchable. This is not only structurally useless junk that is grossly negligent and dangerous because of the lack of protection against contact. I have not returned it because of the low price, this is not worth the effort, threw him in the trash! Hard to believe that something is for sale!
