The USB ports are strong, must be forced to insert and remove the cables. Inputs 1, 2 and 3 deliver 1.0 A (typical USB load) and 4, 5 and 6 reach 2.4A Max (fast charge). This extra power is perfect for hungry devices such as a tablet, a smartphone or a big modern pregnant.
The case remains sober: Lunique green LED lights up discreetly low power when the unit is mains powered (long detachable grip plate is provided). No big blinding light that illuminates your room at night as this is too often the case with chargers and other high-tech devices.

Without connected device, it consumes nothing, i tested with a Power Meter Energy Monitor 3000 and consumption varies between 0.0 and 0.1 watts. You can leave this machine on your wall socket all day without worry about the electric bill.
Jai quickly charging the battery of a headset Logitech Wireless Gaming, one of my powerful Bose speaker but also my tablet Nexus 7 2013 (2.4 on port A, it took my 2:25 from 33% to 100% load) .
Conclusion: this is a great charger 6 ports (including 3 rapid charge) which will replace six copies, with a great quality / price ratio knowing quun charger 1 port can cost 20. So you save about 100!
Buy them if you are techie and you spend your days to recharge all your devices, including the greediest.
