I got a magnetic cable charging set which is very handy. It comes with several USB plug ends. You plug the plug ends into your devices and leave them there. It comes with several usb charging cables that mate with the plug end, for easy connection.

I was thinking something* like* this to adapt it: https://www.amazon.com/Fucung-5-5x2-1mm-Connector-Adapter-Converter/dp/B07G5DS6J4 But I need to make sure I match our barrel connector and center negative. Anyone know what the exact spec is for the Model 100 connector? -- John.
