As long a the laptop power supply isn't rated higher than the inverter you should be OK.

Typically a laptops power supply is approx 75 watts total power consumption.

13 Amps x 12 VDC = 156 Watts available.

Given operating losses for the inverter itself you should still be way under the capacity for the inverter listed using your laptop.

The 20 amps noted is for max output from the inverter.

Just don't try to make coffee...
