- 20,000 mAh is the rated capacity. Anyone who has tested 18650 batteries (which are the cells typically used in these battery packs) knows the rated capacity != tested capacity.
- Watthours is more important than amp hours
- Tested watt hours as typical loads is more important than amp hours
- It's very normal to see tested capacity to be roughly 70~80% of rated capacity.
- This commenter said they got "At 18W average, I pulled out 55.4Wh" on the Haribo [0]
- The generally considered "gold standard" for ultra light batteries in this range is the Nitecore NB20000 Gen 3, which regularly tests around 56 Wh.
So yes the conclusion is correct - you get roughly the same amount of capacity for a typical load (18W phone) for a cheaper price and slightly less weight. Very curious what battery cells the Haribo uses.
