AC adapter for EQ6

What I did was to buy a second DC adapter from KW Telescope, cut the cigar lighter plug off one end and crimp on some Anderson powerpole connectors instead.
When I want to use AC, I plug this cord into my 13.8V DC power supply (that has Anderson powerpole connectors on its DC output).
When I want to use DC, I plug the cord into into a small RIGRunner on the side of my battery box.
The AZ-EQ6 is quite flexible as regards voltage (see the user manual).

If you're in an observatory and will be running other stuff (ie powered USB hubs) Look into a 300-400W computer power supply. These have lots of 12V and 5V power available and should be available from computer stores for less than $40. If you're looking for a large 12V supply, check with providers of 12V supplies for Amateur Radio equipment. These are extremely well regulated, have no noise on their output, and produce 15-30A or more at 12V.

For a stable 12V supply I use an old atx psu from a dead pc.

If it works with the EQ-6, then I'm mistaken about the M plug being needed.

I'm planning on setting up a home observatory and want to run an AC line out to it for my computer, camera and other gear. So I figured I might as well find an way to power my EQ6 as well. Does anyone know of a reliable, well made adapter for it?
There are any number of small power supplies that will do the job. You want one that will supply 2-amps minimum. Simple solution? Orion sells a wall-wart supply that works fine.

It may work but you're probably pushing your luck a bit. George's pictures and explanation are correct. If you use a 2.5mm plug in a 2.1mm socket the center pin may make contact (and will especially if it's been split or opened a bit) but over time you should expect intermittent power issues.
The Meade LXD 75 AC adapter works great for my Atlas. 12V, 5A. It's about 59 USD. I bought mine from Astronomics, but last time I checked they weren't carrying it anymore.

Yep, they sure do. The Meade adapter I got works for it too. It's 5 amps as well.
Note that the Meade adapter may result in power drops because it has a 2.5mm center post tip whereas the Atlas has a 2.1mm center post socket.

Thanks Ed, I'll take your word for it. I'm not too proud to admit if I'm wrong . I have noticed some oddities like temporary blinking at times when a slew has started, but I have never lost power and this blinking only happens once. I appreciate being informed.
If the pin is spread enough, the 2.5mm adapter will work and I have done this plenty of times in the shop. But the one time it won't work is when you are in the field in the middle of a long imaging session and you get a momentary power loss and loose your alignment and image. Nobody likes it when that happens.
