After an ultra-fast delivery in a neat package, I open the box of the product tidy and am pleased to see the aesthetics of the product. The beautiful shiny black had its effect and plastic shell is quality. Furthermore, the small case and the charging cable are welcome ....... If this is a size a little bigger than what I had envisaged, begins well. As soon as I plug to recharge and all goes well. Charging is completed in a very reasonable amount of time because the product is already supplied half loaded. It was after all breaks: whatever I plug the device (iPhone 5s, iPhone 4, iPad 2, iPad Mini) and regardless of the connection used (Apple-branded or generic) Anker Astro E4 does not detect every time a device is connected ....... and when he does, he charges randomly adding a few percent and stay on well before the full charge. We must go about it several times to charge my iPhone 5s which in any case shall never exceed 99% ........ I am extremely disappointed by this equipment ....... and am the more I am very pleased with another device of the same brand (USB Hub 3) bought it a few months ago .... ... It's always sad hardware that shambles input ...... and that's all the more sad that I have to waste time to send it by post and endless queues!
