What are the dimensions of the barrel plug for GS205v2 ethernet switch power adapter?

I've lost my 5V 0.7A power adapter for my NETGEAR GS205v2 ethernet switch so I'm looking for exact dimensions of the barrel on the power plug so I can get a new one i.e. the diameter of the outside and inside of the barrel, and the barrel length, in millimeters. I can sort of guess-timate using a ruler but I'll almost certainly end up getting one slightly too big or small, so I'm looking for the exact specs please. Thanks so much for any help!

    The tiny GS205 and FS305 have 5.5x2.5mm barrel plug. As you correctly mention, the power supply runs on 5V, drawing max, 0.7A.
