Real life experiment: constantly charging MacBook Pro with 12V adapter in comparison to using AC to DC power inverter and charging with 230V as usual. This experiment compares both solutions, see which one is better and by how much!
If you have not seen my previous experiment using both MacBook Pro and external display via inverter, you can find it by clicking here.
Both “Goal” and “Details” will be the same as in previous experiment, so it would be easy to compare results objectively in this article:
Goal: work the same as every day, just be connected to the 12V…
Goal: work no different than every day, just be connected to the 12V (12.8V to be exact, as this is LiFePo4 battery) DC battery and see how long can it last.
Details: programming work (no video editing or gaming, which could increase power consumption a lot) on a 100ah LiFePo4 battery with a MacBook Pro 16" i9 (2019) with additional external 24" display (Dell U2415).
Firstly I connected 300W inverter to the fully charged lithium battery. Then I connected regular MacBook Pro charger cable together with external monitor cable to the inverter. …
