External battery power for off grid location

  Paintfly 10:24 26 Jun 2018

I have a Mac Air 11" 2015, which I want to use on battery only in a remote location. I am trying work out a system of extending the measly battery life. I have quit apps & turned off wifi, reduced screen, keyboard brightness to absolute minimum, but still only get about 2-3 hrs working in Word. I need enough juice for at least an entire day. Power packs don't appear to be a feasible option (Quikertek is prohibitively expensive)because of the Magsafe power connector. Would I be better of buying an ipad, which can be recharged with power packs or is there a way round this problem with my MA?
