the same thing applies to many things
say you have a laptop and it came with a 180w charger
and you plug in a 90w charger it will work (or should) but it will take longer to charge and that charger is going to get really hot because it is being worked 100+ % of what it was designed for.
and if you plugged in a 240w charger it is going to still charge the same time or very close to what it did with the 180w only now the charger is under less strain and won't get very warm.
electrical devices are normally designed to only "draw" a specific amperage, to a certain degree, if you plugged in a 600w charger to that same laptop it's going to overload and melt the inverter and likely start burning.
