Best power bank for pro users

With 140W of power, the Anker 737 PowerCore 24K power bank is beefy enough to juice up a laptop. It's hefty — 1.3 pounds and the size of a soda can — but that's the tradeoff for this much power. The color display shows you how long it will take to charge your device. If you need serious portable charging, this is worth the investment. It comes with a USB-C to USB-C cable designed to handle the high wattage. — MF
