Compact charger which also neatly brings, according to my tests performance. There were the same two smartphones (Sony Xperia Z and Samsung Galaxy S3) and a 7 "tablet loaded from Lenovo. The batteries of all devices are loaded quickly and corresponded to the loading progress of the manufacturer supplied charger or surpassed this part even. The charger warmed while only slightly even after prolonged use, which gives the impression that here quite all ports can be used to charge without equal the voltage significantly breaks or something promptly the "stewing" begins. Overall, I am therefore of the product very enthusiastic . It should be said about that the device is with me for only a few days in service and I still can show no long-term experience. but I do not hope times that it gives up the ghost right after a couple of weeks. :) For me, definitely reach the target. In the holiday now only this part goes with and it no longer needs to carry around its own charger each family member. The quarrel about the free outlets has thus an end.
