Okay, I've got one for you, and I rarely see any DJ ever do this. You might consider getting a spare power supply (power cord / AC adapter) for your controller. AC to DJ power supplies do fail, and since it is not an easy to find item, if it goes out the day of your gig, you are screwed.

For my Denon MC7000, I can order the adapter online through Denon for $30. That way I am 100% positive that it will have the right voltage, amperage, tip size, etc. and is guaranteed to work.

Or you could just get off Amazon a universal one with switchable voltages and tips. The one I linked should have enough amperage to run a controller (the Denon takes 4000MA, and that one is up to 1 amp. Just be sure when you get it that the tip fits, and that you are using the correct voltage, tip polarity, etc. I can help you with this if you need - PM me.

Do you have a picture of the sticker on the bottom of the machine? Oftentimes they will say the power requirements.

If a normal headphone plug is too big for the charging jack, then it’s probably a 2.5 mm jack.

But the jack size isn’t the only thing you need to know. You also need the power requirements. If they are on the sticker on the bottom, we can find an appropriate charger. If not, here’s someone selling a somewhat expensive one.

Edit: I did a bit more research and found that the requirements are probably 7.5v and 900 mA. Here is a universal charger that has a 2.5mm jack and the option for 7.5v.

You may want to look a bit more yourself. Your requirements are:
-2.5mm phone/mono jack
-7.5v and at least 900mA (mA can be higher, 1000mA = 1 A)
-If you can’t find one with mA listed, make sure it is 7.5v and at least 8 watts.

I wasn’t able to find the polarity. So I don’t know if the tip or the sleeve should be positive or negative. That’s usually printed on the sticker requested as a little diagram. The tip is usually positive, and the sleeve is usually negative, but it would be impossible to know for sure without more info.

Did you ever find one? They are seemingly impossible to find with the right size tip. I was thinking about ordering this one, but would rather have the correct OEM one. https://www.amazon.com/Universal-Transformer-Reversible-Positive-Negative/dp/B01LBX8D58
