What is the power of a laptop and how big is it?

The general notebook power should be around 30-50W

Under normal circumstances, you will know if you look at the battery. The laptop battery is 12V and the capacity is 4000mAh. Even if it can only last 2 hours, then 12V * 4A / 2 = 24W, so the power of the laptop is between 20-30W. The power is just the maximum output that can be achieved.It does not mean that the notebook power must be completely consumed, just like the output power of Three Gorges is several million kilowatts, but no matter how much power, your 40W bulb still consumes only 40 joules of energy per second. It is impossible to reach several million kilowatts. Because the power adapter has heat loss, the input power of the adapter is larger, about 50W.
