Use lithium ion car jumpstarter to charge netbook?
Your idea of the cable to cigarette lighter to AC/DC converter to wall wart to laptop would work, but you are right - that is a lot of connections. This cable would also be suitable for that application, using the 12V output on the side of the GOOLOO. That 12V/10A port should not hurt your laptop, but I would be very hesitant to use the port that is for jumping your car - that has some serious power capable of coming out of it. 

The best cable would be something going from the 12V/10A output on the GOOLOO straight to your netbook. From the looks of this charger, your netbook has a 5.5mm connector. You would have to figure out the dimensions of the GOOLOO adapter (first link). From the questions/comments on the GOOLOO charger page itself, someone states it is a 5.5mm adapter (same as your laptop), but it's up to you if you want to trust that. 

You could give this cable a try, and see if it works! If that cable doesn't work, you'll either need to look for a cable with both of the correct connections, or if you are electrically savvy, make your own connector by hacking the GOOLOO adapter and a netbook charging cable.
