I gave away several pieces and variations of these beautiful and basically very convenient outlets duplicators in use and. Are expected soon to be 10 in total. But: Some of the outlets are so stiff because of the built-in child protection that you get normal thick safety plug purely only with the greatest effort. I'm really scared, wreck the whole thing and must be exactly to hold otherwise would possibly break the wall outlet. Are they not written in other reviews. So true, unfortunately, and not only on a "mon part" The USB ports apparently provide relatively little power. Appearances 2.1 A. I suspect for both together. Since the original Samsung plug loads with 2A significantly faster at a terminal. What this also annoys me is the spongy indication on site and Packaging: When voltage is 2x5V (ie whether there would be a doubt), but the current just mentioned 2100mA. Because then you can guess whether each port or even total. In my experience, I am sure, as a whole and not even on a fitting, if the other is empty. Given the price, I find such defects then but unacceptable. Therefore, depending on a star deduction for each defect itself and another for the relation to the price and the concealment of property.
