I am impressed with the power it packs with a full charge and how quickly it recharges on solar power alone, indicating good battery life for the portable-power-bank.
I was able to recharge two iPhone 11 Pro phones to full capacity when they were down to about 1/2, and the battery still had life remaining. This shows that the battery life of my portable-power-bank is good.

Experiential insights by users
I bought the product based on compatibility information from others, but it turned out to only be compatible with iPhones, not Samsung S22.
