Personally think that the power adapter is a constant voltage output, your output voltage is 9V, and the maximum output current is 1A. As long as the voltage of the connected device is 9V, the maximum current can be connected to no more than 1A. The first fan is connected without problems, the second one may not turn or the slow, and the third one is likely to burn.

For a constant voltage power adapter, the following metrics are required to replace the power adapter:

The replacement new power adapter output voltage is the same or similar to the output voltage of the original power adapter.

The replacement new adapter has a maximum output current that is not less than the maximum output current of the original power adapter.

The replacement new power adapter has the same definition and shape as the original power adapter interface (if a plug is available).

Other non-primary electrical performance indicators of the replacement new power adapter are not lower than the corresponding indicators of the original power adapter.

In fact, for ordinary users, the concept of power supply is generally "can be used", it is called a good power supply, do not understand the real good and bad points of the power supply, it is even less aware of the importance of the power nameplate for power quality. Actually for a power supply, the most important information power supply "rated power". Rated power identification is very important for a power supply. Only when we clearly understand the "rated power" can we really understand whether this power supply can support the needs of our platform. If your platform consumes 300W, then choose a power supply that doesn't know the power at all. The absolute event is very unreliable. There is one more thing to say here: the "maximum power" of the power supply is not "rated power."

We often see that some power supplies only indicate the "maximum power" of the power supply, and there is no "rated power", which makes consumers mistakenly think that "maximum power" is "rated power." In fact, the two can't draw the equal sign. The "maximum power" is the "peak power". The maintenance time is extremely short, and it can't meet the needs of the stable operation of the computer. Therefore, it is very important to see the rated power of the power supply.
