Your charger should work fine, just make sure the connector is the correct polarity.
Square Off Kingdom Power Supply
Hi,
we lost the power supply during move. Can you send me a link to the correct power supply? I have been to an electronics shop, but they were not sure how the polarity is and didn't want to destroy the board.
thank you very much,
Christian

You might try asking Square Off directly via https://squareoffnow.com/contact-us.
I tried multiple times, and they always sent me a link to a page where I can buy it within the US. Not helpful if you life in germany
They also don‘t seem to understand my questions as they only send the link.

Gotta love knuckleheads. You might contact member essmanchay and ask if he knows if his replacement was center-positive or center-negative. If he has the manual for the board it might have the information. If all fails I'd suggest trying to find someone who knows a little about electronics to help determine if you need center-positive or center-negative. Center-positive is far more common (near-universal) but I have been surprised from time to time...there's those knuckleheads again! Good luck!
So, I took a lucky shot and succeed. Center PIN is positive. Found this Adapter on amzn:
Input voltage: AC 100V - 240V ~ 50/60 Hz
Output voltage: 12.6V DC (direct current)
Output current: 2.0A
Plug: ø 5.5mm / 2.5mm
Plug inside is "+
Maybe it can help someone the next time
Thanks for your help Dave and Oliver who helped me to find this thread

Hi All,
Has anyone replaced their power supply to their Square Off Kingdom board? The output is 12.6v 1900mAH.
If so, which one are you using? The closest I could find was a charger output of 12.6v 2A.
Thank you!
Oliver
