I got the Anker 737 from the previously posted deal hoping to run my camping fridge for a day at the beach on New Years, but unfortunately it did not work as the USB-C to car socket adapter was delivering 20V which means the fridge thinks it is a 24V battery low on juice and shuts off. So in a pinch I saw this one on sale and grabbed it.
The capacity of this is 153.6Wh, which is 80% more than the Anker 737 (as this is 12AH at 12V), and this is cheaper as well. It has a car socket plug which allows the higher current lower voltage draws in addition to the USB-C, which maxes out at 60W (That is the biggest drawback I can see, but then you can get a car socket to USB-C thats rated for higher).
The other drawback I can see is that it can't be taken on a flight (without approval), but I wouldn't want to be lugging a 1.5Kg powerpack on it anway.
How does it compare to 20000mA portable power banks?
It is like 60 times more capacity when compared to this?
