Well,
The
toy arrived.
charged it fully as instructed.
And connected the
45-liter refrigerator in to simulates night camping while the fridge is disconnected from the main battery.
The starting points of the fridge temperature was 6 degrees Celsius, and I've set it to 4 degrees, which means that the compressor worked in full capacity for 15-20 min' and after reaching 4 deg, it worked in short intervals of few minutes each time (about 2 per hour), to keep the set temp.
The energy draw measured 2.5-3 amp while the compressor worked.
This small little Chinese-toy-Energy-Pack managed to keep the fridge's energy need for 12 hours and twenty minutes..
Room temperature was 24 degrees.
