When you switch on your computer the peak current is about 30A till the 470 uF in the power supply is charged. It must be a requirement by some standard and the Chinese way is to correct the label. They put CE mark on their products without even knowing what it means.Perhaps the pulse width of the peak is a factor. But generally pulse width is at least 1 cycle such as motor surge currents at 8x on start at peak voltage.
But then for $8, and no detailed spec, what do you expect?
The first number appears to be the "Test Amp Rating", effectively the current at which it is calibrated.
The second number is the maximum load current, which is generally 666.66% of the Test Amp Rating.
