I just received a QA403 and I am seeing a low voltage from USB power in the app (4.317V). I tried a couple of hubs as well as directly connecting to my laptop and all read 4.3V or lower. I am using a short USB cable with 22ga wire. While the unit is working this voltage looks too low for full and reliable functionality.  
Any suggestions on a powered USB hub that will deliver appropriate current without loading down the voltage?

Have no Problem so far with it.

When i remember me right 4 Ports can handle each 1,5A at once

May be an Alternativ one, with 4 Ports up 1A each:

Thanks everyone for responding.  
I ended up using the Ikuai hub off Amazon. It was cheap, arrived quickly, and worked.  
It is also essential to us a USB cable with 20ga or larger power conductors. Just using any USB cable I had around caused voltage loss. I am now seeing 4.75V.

Glad it is working out for you. I also like having the on/off switches on the outlets 😀
