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.
Charging from sunlight is slow and depends on the weather.

What can this power bank realistically cover?
Every row checks both energy and power. It stays a planning aid: the exact device and cable must also match.

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 Promate SolarTank-10PDQi charge a phone?
Our planning estimate is about 1.9 full charges of a 15 Wh phone battery. It assumes an estimated comparable value of 37 Wh and that 75% of that stored energy reaches the phone.
Can the Promate SolarTank-10PDQi 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.
Can the solar panel fully charge the Promate SolarTank-10PDQi in one day?
Do not assume so. The manufacturer states: 50 hours in the manufacturer's specification. Weather, angle, shade and heat can make it even slower.
