Hello I was looking at charging a a 13” MacBook Air laptop aswell as powering a Fridge Freezer 43.5L unite and had a some of questions.

The setup:

Device:


  • 2014 13” MacBook Air (7160 mAh battery / 54‑watt‑hour lithium‑polymer battery / 45W Power Adapter for charging the laptop)
  • 43.5L Fridge Freezer at 0.88 Ah/h @12V

Power:

  • Battery 12V - 120Ah
  • 200w Folding Solar Blanket Grade A

With the 12V - 120Ah Battery while running the fridge how much power would there be left to charge the laptop and on a single charge of the battery how many times might it be able to charge the laptop 0-100 before the battery it self needed to be re-charged via solar?

Thank you for your time and I hope yo have a great day!
Andrew.
