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.
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!
