The charger can charge up to 5 devices, and with just one outlet. Since it is compatible with 100-240V 50-60Hz, I can practically invite all over the world all my technical toys, the 2 ports deliver 2.4A enough for tablets, the other 3 are suitable for MP3 players and mobile phones. And the price of a normal 1 Port loader!
Addendum: After some time of using my favorite, with the original high-quality cables loose 2A arrive at the device to be charged. From the cheap thin cables I leave now the finger.
