Echo dot power connector

[DaveLanks]

I just took delivery of an Echo Dot with clock and find the power lead is too short for my requirements.  I can easily purchase an extension but need to know whether the connector plug is a 2.1mm or 2.5mm.  Advice greatly appreciated, thanks.

I don't know the answer but it seems if you search for power cables on amazon for that dot, it should say in the specs.  just be aware that is uses a different power cable than the first two generations.
