They are all power supplies with the same nominal voltage and different output currents. Can they be used on the same laptop?

The power supply voltage is the same, the output current is different, it can be used on the same laptop. The basic principle is that a power supply with a large nominal current can replace a power supply with a small nominal current. It is estimated that some people will think this way, thinking that a power supply with a large nominal current will burn the notebook because the current is too large.

In fact, the current depends on the load when the voltage is the same. When the notebook is running under high load, the current is larger, and when the notebook enters the standby mode, the current is smaller, and the power supply with a large nominal current has sufficient current margin. On the contrary, some people use a 56w power supply instead of 72w to use it without any problems. The reason is that usually the design of the power adapter leaves a certain margin, and the load power is less than the power supply power, so this kind of replacement is feasible in general using. But the remaining power margin is very small. Once your notebook is connected to many peripherals, such as two USB hard drives, then the cpu runs at full speed, and there is a base on which an optical drive reads the disk at full speed, plus simultaneous. It is probably dangerous to charge the battery.
