I don't know what are u comparing on. MI power banks are typically 5v 2.1A but adaptive fast chargers from Samsung is using adaptive fast charging 9v 1.67A. MI power bank don't use that, neither they have the 5V 3A dash charging on USB C..
I think Xiaomi 10000mA Slim version has fast charge 5/9/12v for both input and output port. The 20000mA one has fast charge to input but not output.

Samsung one is fast charge 5/9v for both input and output.
Capacity is depend on each habit and usage. I think 5100mA is good enough for at lease 1 charge to most handphone. Good thing for lower capacity is it also charge up faster. I have a Xiaomi 16000mA one, typically required 7 to 9 hours to get it fully charge. Is far too long to be useful unless you have 2 so that you can use the other one while one is charging.
