Almost perfect, because it lacks a notice that the charger told to refer to. To be honest I did not understand the technical data that is entered on the charger. Apparently there would have taken two of a kind and the other 2 of another type. I guess it's the amps. But good out of it after a day of use I'm pretty happy. All recharges a suitable pace. I have not thoroughly tested the difference between the loading speed of a camera and four at the same time, but it looked more than adequate. The blue LED is fun or boring, as desired. Level manufacturing quality is not bad at all. There are USB ports that leave a little peanut but it's not the end of the world. Considering the price, I think buying another. It was 14.99 without shipping costs (2) against 6.16 and 7.90 here in total with shipping. When I think that in conventional stores a charger with 2 USB ports sells 14.99, can of a supermarket brand stuff. Only regret: we see that the part that plugs into the electrical outlet withdraws, we can put another type of outlet. Like a charger Macbook Pro actually. Convenient for travel but: NO INFO on where you can buy different taken to different continents! For me it is the only detail annoying. I survive but it would have been very significant.
