I really don't know if every unit behaves like this, but mine has so many problems it's almost unusable.
The USB-C supports quite a few protocols.
The capacity is indeed close to 150Wh
The USB-A (and C) QC2.0 port can't negotiate a stable 9V 2A; it constantly switches between 5V and 9V and the current drops to 0 most of the time, so the device charges extremely slowly.
The capacity measurement is completely useless, it drops from 100-1% faster than it should, and then it lasts for an hour on 1%.
the display glitches when different devices are connected (segments disappear, it flickers)
It completely randomly stops charging (input voltage is still, for example, 20V but the current is zero). It can stay like this for hours until I manually unplug it and plug it back into the charger.

Except for the weight and size, which must be taken into account with such a capacity, the powerbank is otherwise great and I am personally very satisfied.

This is an excellent power bank, comes with an excellent cable, charges well, and charges a mobile phone in just 20 minutes to 80%, while remaining with 93% power
