AC input not matching DC output
For a switching power supply the maximum current will occur when the AC voltage is at its lowest value hence, expect the maximum power (ignoring power factor effects) to be 100 x 2.5 = 250 watts. Then of course the value stated on the label will represent a worst case scenario and not a typical situation.

If the output is rated at 130 watts then typically the input power will be about 15% to 20% higher at maybe 160 watts.

Power factor can make \$V_{RMS}\$ x \$I_{RMS}\$ appear too high in terms of watts and this also possibly contributes to your misunderstanding.
