Another point to watch out for : the EQ6 has a DC socket with a 2.1mm dia pin.
However powerpacks (or 12v cig plug leads) can have either a 2.1 or 2.5 internal dia plug. They look almost identical. The 2.5 plug will work on a 2.1 socket pin, but the connection is not as secure. As the mount slews, you might find intermittent power losses if the plug moves in the socket. Very annoying. That was my experience.
Jaycar has an adapter for 2.5 to 2.1 mm dia for a secure connection, if you have this problem.
Unfortunately industry has multiple standards for these things.
Skywatcher use a 2.1 pin socket, Meade uses a 2.5 pin.
ie 'we like standards, that is why we have so many'
enjoy your EQ6. It is a good mount.
