Can I charge my notebook with a power bank?

I have a Lenovo Yoga 2 notebook and the following power bank:

The Sunnybag POWERBANK 10,000 has a USB-C input (5V, 2A) for charging the battery and a standard USB output (5V, 2.1A) for charging mobile devices.

Can I charge my notebook with the right adapter with this power bank? If so, which adapter do I need?

No, because it works with 20 volts.

Which power bank and adapter do I need? I have the SunnyBag ICONIC - can I maybe charge the notebook directly from it? https://www.amazon.de/...07J58Y5K7/

I quickly found only 5 volts to 12 volts DC-DC converter in the milliampere range.
