definitely support charging via usb-c
fast charge
the power bank itself can also be charged with lightning
probably weight and size, but it has to be taken into account when someone buys 30,000 powerbanks will probably not be small and light

Powerbank mamuz some 3/4 years. Bouzial with my own awkwardness, I managed to break the USB ports and instead of complaining, he decided to fix them himself. Over time, I stopped showing 9V output during fast charging, even though it works.
Now, if I had to choose a power bank with 30,000 mAh capacity, I would rather take the Baseus Bipow Digital Display Power bank 30000 mAh 20 W Black wheel where it would be plus 20 W instead of 18 W for a lower price link to the power bank: https://m.alza.sk/baseus-bipow-digital-display-power-bank-30000-mah-20-w-black-d6994082. htm
high capacity
unfortunately over time it stopped showing 9V fast charging whenever it goes
slower charging - without fast charging, I recommend charging overnight

After a year of use no problems, just a little heavier, but that's the tax on capacity.

After two years of minimal use it stopped charging, replaced just before the end of the warranty with a second piece that stopped working right from the start, so I'm out of luck.
