In blog post “My Fridge & My Portable Power Station” I managed to get a maximum of 778 Wh out of my portable power station with a rated capacity of 1260 Wh.

Thinking that quite some power got lost in the AC inverter, I set out to measure the amount of power I can get with its 12V DC output.

I configured my electronic load to draw 5 A:

The portable power station displayed 65 W output:

And I only got 673 Wh out of it:

That’s even worse than for 230V with the inverter: 53% of the rated capacity.
