Maestro Model A Coaxial Charging Port

What is the size of the charging port on a Maestro model A? Thanks

The Maestro did ship with a DC power cable. You might want to look in the box.

However you want a 2.1mm cannon connector.

The shaft length is about 6MM

The connector pin is 2.1mm.

I highly recommend Switchcraft parts if DiY.

First, to set the stage: There is an internal battery and then there is the external (user supplied) battery slot that the Maestro rear removable panel covers.

The internal (very short term) battery is charged with the power jack and when turned on. That may take an hour for a discharged battery with just powering up the Maestro (using the AC adapter or via 13V PS.

The USER external battery is NOT charged from the Maestro. The A model was designed to charge that battery but, in the era of exploding user batteries, was disabled. In the very first A version shipped there was a USB wire and users were requested to push it back into the main case. Models delivered after the warning did not have that USB wire included.

That leaves it for the USER to charge their own USER EXTERNAL battery. Mine takes a few hours to charge, depending entirely on the charge current of whatever charger I use.

I was actually asking about the size of the DC power port on the Back of the Maestro. My power supply died and I wanted to rig up a cable to run it directly off my base power supply. Thanks again and 73

Did you look in the box for the cable that comes with it?

Lawrence Kellar KB5ZZB

Yes I did Mike. I put it up in a very safe place......so safe I can't find it! Tnx

You won't be the only person who has done that.

When I do it, I imagine I have one and I want to put it in a safe place. Then, I go there and find the original.
