So, can I charge the new mbp with a 10000mah powebank through a usb-c port?

Jesus, NO! You can't charge your MacBook with a 10,000mAh power bank (at least not to full). mAh is a useless indicator for comparing the "size" of a battery because mAh are dependent on the voltage.
A unit suitable for comparing different batteries are Wh because the value is not dependent on the voltage and actually tells you how much energy the battery stores.
The difference in voltage is why there are phones with 6,000mAh batteries (which the 14" MBP also has), yet the phone would not be able to charge your 14" MBP to even 50%. Why? Because both use different voltages. The 14" MBP has a whopping 69.6Wh of capacity (ca. 11.6V of nominal voltage) while typical phones with 6,000mAh batteries will have around 23Wh of capacity due to their lower voltage of just 3.8 to 4.0 Volts.
The same thing also applies to any power bank. If you want to know how many times you can charge a device with a power bank, you NEED to look at the Wh unit, not the mAh / Ah unit. The average 10,000mAh power bank can store around 32Wh of energy. So that's not even close to being enough for a full charge of a 14" MBP let alone the 16" MBP which comes with a 100Wh battery (8700mAh).

OMG, thank you! finally someone can give me an idea of generally how many WH 10,000 mAH is. ive been looking for the answer to this for so long and its so hard to find a straight answer.

Watt-hours is also a much more intuitive measurement. 32 watt-hours means you could light up a 32 watt light bulb for one hour, or a 16 watt bulb for two hours."The average 10,000mAh power bank can store around 32Wh of energy"

You simply multiply the voltage of the cell by the mAh."The average 10,000mAh power bank can store around 32Wh of energy"

My Xiaomi 30,000mAh bank for instance is 3.7V, which is 111Wh. The problem is, most other companies are not so forthcoming with the specs because they use low quality cells with lower voltage.
