It will
Two cables (USB / micro-USB) of about 20cm and 60cm,
and a micro-USB adapter and
a 30pin adapter for Samsung tablet and
a small bag supplied.
It can be connected for charging two devices at once. For example, tablets is a 2.4A output.
About the third port, the device in about 9h. be fully recharged.
Furthermore, an on / off button is installed over which the built-in flashlight is controlled. This lights up approx 130Std.
I would buy the device again.
