Energy is not the same as charging power. Check your device and cable too.
Two-device output is shared at 15W, so simultaneous charging is slower.

Based on a 15 Wh phone battery, assuming 75% of the power bank’s stored energy reaches the phone.
The charging standard and the cable determine the real speed.
The combined output rating is not necessarily available from a single port. Check the individual USB-C limit and power-sharing specifications.

Capacity and speed are different decisions.
A higher mAh figure describes charge quantity only after voltage is considered. Watt-hours compare stored energy; single-port watts describe how quickly one compatible device can charge.

Practical answers from the listed specifications.
How many times can the Belkin Power Bank 10K with Integrated Cable charge a phone?
Our planning estimate is about 1.9 full charges of a 15 Wh phone battery. It assumes 37 Wh rated energy and that 75% of that stored energy reaches the phone.
Can the Belkin Power Bank 10K with Integrated Cable charge a USB-C laptop?
This is not a strong general laptop choice, because the fastest USB-C port delivers at most 20 W. Some efficient laptops accept it; check the exact laptop input.
Does one port deliver the full 20 W?
The combined maximum and the fastest individual USB-C port are both 20 W. With several devices the distribution can still change.
