Supplied are:
1x Charger
1x connection cable
The charger features a blue (very bright) LED indicating that it is ready for operation. Furthermore, it has a power connector on the back and 4 USB ports on the front. It must be noted that the charger has 2 ports with 2A charge current and has 2 ports with 1A charging current. To me that's not a problem. An on / off switch one seeks in vain unfortunately. This would certainly be a meaningful improvement.
My conclusion:
A practical aid if you have many power-hungry USB devices.
