Is connecting a higher-amp (e.g. 2 A) adapter to a lower-amp (e.g. 1.3 A) electrical device safe?

I wonder if it will cause the adapter to over heat and cause fire or cause damage to the electrical device.

No it won't overheat the adapter. That's designed to deliver up to 2 A, and everything less than that is safe. If you disconnect the device the current will be zero, and that's also safe. The adapter will supply the required current, not the current it can supply.

Never do the inverse: connecting a 2 A device to a 1.3 A adapter, though.
