I'd urge you to order the plug from Elecraft. It's an Elecraft part #E620032,
describes as 2.1mm male connector.

R/S will have something which will work, BUT those they sell DO NOT protect
the inner conductor of the connector from shorting out if left to lay out on
the desktop.

The Switchcraft plugs which Elecraft sells have a slightly recessed center pin,
which is mostly protected from accidental shorts to ground. The R/S versions
are NOT so protected.

Worth getting it from Elecraft.

Regarding wire... I'd suggest you use #16 or larger, #14 if you can find some
with insulation that doesn't overwhelm the power plug.
