How many times can it charge a phone?

At 20000mAh, expect roughly three to four full charges of a typical 4500-5000mAh phone, less after cable and conversion losses.

Does it support fast charging?

Yes, up to 22.5W with Quick Charge 3.0 on compatible Android phones. iPhones charge at standard USB speeds, not fast charging.

No. 22.5W is far below what most laptops need, and there is no USB-C Power Delivery output at laptop wattages.

Use the USB-C port with a wall charger rated 22.5W or higher. A basic 5W charger will take most of a day.

Typically the power bank and a short charging cable. A wall adapter is not included, so you need your own.

Yes. At 20000mAh (about 74Wh) it is under the 100Wh limit most airlines set for carry-on batteries, but it must stay in the cabin, not checked bags.
