USB2-HUB-AG7 barrel adapter size?

I recently picked up a the AG7 USB hub and I have to say it is probably the best hub that I have ever purchased, but to make it perfect I need just a little bit longer of a power supply cord. I tried searching around and wasn’t able to find the exact size of the barrel adapter that the power supply plugs into, does anyone else know?

Thanks in advance!

Hi Darren,

Thanks for posting your question here! The power adapter that comes with the Plugable USB2-HUB-AG7 outputs 3A through a center positive coaxial barrel connector with OD-3.5 mm and ID-1.3 mm.
