So I have this portable electronic device with a rating of 1.5 Amps over 12V. If I supply it 2 Amps over 12 V, would it be damaged? Should I instead supply it with 1 Amp over 12V?
Thank you.

Kind of.
If you supply your device with less current it probably just won’t work properly.
If you use a higher rated supply then the device should still only take 1.5A, as that’s all it needs. But if it’s poorly designed or has a fault then it may take the full 2A and that could damage it.
So while it will probably still work with a higher rated supply it’s not the best idea and could range from potential damage to your device to a safety/fire risk.
This gets especially important if you’re talking about charging batteries. Most modern batteries have intelligent charging systems.to handle voltage/current, but older ones may not and a daged battery can be very dangerous.
