Yes. It has a built-in solar panel designed to provide solar charging.

3. Can I charge it from electricity?

Yes. It can also be recharged through its USB charging input.

4. How many times can it charge my phone?

The actual number depends on your phone's battery capacity, the power bank's usable energy, conversion losses, and charging efficiency. A 20,000mAh rating should not be interpreted as 20,000mAh of usable output at the phone's battery voltage.
