Question before buying the Presonus Audiobox 44VSL

Hi

Im about to purchase the Presonus Audiobox 44VSL

I would like to know if the unit can work / powered only by the USB cable coected to my laptop.

In other words without using the AC cord.

Im asking because I live in europe and I want to buy it in the US and the AC level isdifferent here 200 vs 120 in the US

Thanks
