They gave you a secondary line that says Rated Capacity because they are calculating a real use capacity by taking into account loss of efficiency due to heat and various other factors. This is normal for all batteries. You will not be able to utilize all of the cell capacity of the batteries as no battery is 100% efficient.
Unlike many other power banks, at least they gave you both figures. Rest assured, the power bank indeed contains 4x 5000mAh 21700 cells, so it is 20,000mAh at 3.7v or around 15000mAh at 5v or 73Wh. Your rated capacity at 55.75Wh is more realistic which gives you around 76% efficiency, quite a conservative estimate and fairly normal. All battery and power bank manufacturers label their products this way. You will not find any power banks labeled 20,000mAh where you can get all 100% of that capacity. Other brands just don't give you the calculated "Rated Capacity" figure at all.

edit: got it to work after deleting it from my cart and re-adding it to apply the coupon.
anyone know if this supports Samsung super fast charging?

Also, do you have a similar 20k power bank at similar price level ($34) with this level of output (~ 190w) and CCC certification? I'm in the market for one so i'd love to get a recommendation.

BUT - People report on that mode severe heat throttling. My presumption is this is no different here.
So don't expect 140W or even 100W through the whole charge cycle. Mostly Anker, Baseus and INIU consistently have pulled that off - and mostly (almost only) on their premium units (737, B63, Blade - respectively).

I just assumed it uses lifepo cells for the CCC label, since they're less energy dense in return for being much safer. I'm not planning on flying to China any time soon, so that label really isn't a big concern of mine. I'm more concerned about efficiency, and this battery is not as good as my Iniu 10Ahs, my Anker Zolo 10Ah, or my Insignia 26.8Ah. If I do end up flying in China, I will strongly consider this again.
