You could lug around a UPS, the smaller one made for networks. Around $40 or so.

a) that battery pack is USB and AC only. It doesn't support direct laptop dc charging like the anker/romoss battery packs. You are essentially converting 5 volt DC to 117 vac and back down again to 11-19 vdc. You probably lose 35-50% of the pack run time due to the inefficient double conversion

b) Running a 17" i7 gaming laptop from an external battery pack ? You are better off buying a 100 ft extension cord
