Roku Ultra (4660X2) Power Adapter Specs

This may sound weird but I am looking for specifications for the power adapter for a Roku Ultra (4660X2).  Specifically, the size of the DC power plug.  The most common is a 2.1 mm x 5.5 mm, and it certainly is not that size.  I'd like to make a short extension cable for it, but cannot find the desired specifications.

You had two months to find out for yourself, if you did you should have posted for others behalf, if didn't get out a micrometer and measure it yourself.

I help people on these forums all day, but also want to help people will want to help themselves, two months and still just waiting to someone else to serve you, that's pitiful.

Did you happen to find out any of the specs or know the polarity?  I ended up leaving my power supply at my daughter's place in California.  I figured I could leave it there for when I travel.  I have a ton of other power supplies that I have saved from other items.  I figured I may have one that will work if I have the correct specs instead of having her mail it to me or buying a replacement.  If any one has the specs, let me know.  Thanks!

Disregard.  The information is in very small print on the bottom of the Roku.  Thanks.

Ok, did as much as I can.
I used my multimeter and found that the connector is center positive and jacket ground.
But my micrometer will not fit inside the outlet on the roku to measure it because of the center post.
I know 5.5mm is too big cause I tried to fit one in there and it can't even be forced in.

I'm guessing it might be 4.0 or 4.8... So unlike the others in this post, when I get them in and try them out I will attempt to find this post and let you all know which it is.
