advertised capacity is what's written on the battery packs - not what you'd get at some nominal voltage - that's how they all do it.

This is why a 10ah 12v battery is so much powerful than a 10000mah 3.7v battery.
Skeptical of the advertised capacity for the price and size but maybe it's for real.

This is not "how they all do it" lmao. Reputable brands such as Anker or even INIU have very accurate mAh AT 3.7V that can be clearly reproduced by 3rd party testers.
There is no way in hell this will ever give "49800 mAh" even at 3.7V like you're claiming. This device would have over 180Wh of capacity, by that logic. Anyone with common sense would see that this is very clearly impossible. Moreover, it would be illegal in >99% of the world the take on a airplane at that level of energy capactiy.
Do NOT buy this!
