The output voltage, amps and Rc Connector are the same but the plug different. The inspire 1 rapid charger plugs straight onto the battery and you need to cut this off and change to plug that will fit inspire 2 charging hub.
Why mutilate a $100 Inspire 1 180W charger when you can just make an adapter using some crimp on spade terminals wired to a power plug compatible with the Inspire 2's charging hub?
you would need to make sure the polarity is correct though.
