What should you look for in power banks? Capacity: 10,000 mAh fills most phones about twice; 20,000 mAh or more suits laptops and long trips. Output: phones need 20W to 30W, while laptops usually need 45W to 100W over USB-C. Airline rules: the FAA allows power banks up to 100 Wh in carry-on bags, never in checked luggage. Size and weight: a bank you leave at home because it is heavy does not help.
Knowing when to say no matters as much as knowing what to buy. Skip the Anker 737 Power Bank if you want something pocket-sized for a phone only. Skip the Anker Nano Power Bank if you need to charge a laptop or several devices at once. Skip the Anker MagGo Power Bank if you want the fastest charging; a cable is quicker and more efficient.
