Size of CGEM/EQ8 Power Plug

[TrickySpot]

What size is the power plug for the CGEM/EQ8....seem to be some power supplies that have plugs that are just a tad too small and I don't know how to measure them accurately.

Thanks in advance!

I just bought a Advanced VX Mount, and had to find a power supply from a local store. I looked at what the measurements, of power supplies that are regularly sold with the mount, were and found an equivalent. The measurements were described on FLO at least.
AVX and CGEM seem to use the same plug, which has the measurements: Inner/Outer Diameter - 2.1mm/5.5mm and depth of 12mm
