How to choose the right fast-charge power bank
For phone-only use 20 W USB-PD is enough — iPhone and Samsung hit their peak speed. If you also want to charge a tablet or laptop, pick 65 W (MacBook Air, Lenovo ThinkPad). 100 W models also power a MacBook Pro 14″ under full load. Capacity — 10 000 mAh = 2× iPhone charges, 20 000 mAh = MacBook Air once or 4× iPhone, more is not allowed on flights.
