This relatively compact body (it integrates the processor, a simple electrical socket allows connecting to 220V) can charge up to 4 USB devices. 2 taken "iSmart" deliver 5V at 2.4 amps (which is what it takes to load my LG smartphone at normal speed, for example) 2 5V taken with less intensity of only 1.2 amps probably for devices that only support by 2.4A? Anyway you can also connect any device to these jacks, a smartphone is simply reload slower for example.
A final point on the packaging Product: consists only of cardboard and very well thought out it is practical, without making head and without plastic, a very good point!
