Working is hard, and when your laptop is close to dying, it’s even harder. Fortunately, a high-capacity power bank can save the day when you’re low on battery and outlets are out of reach — or if you need to charge your phone and other small devices during a power outage.The Anker 747 PowerCore 26K is the best power bank for laptops that charge via USB-C because it fully recharges most laptops at least once and does so as quickly as possible, yet it’s compact enough to carry in a backpack, a laptop bag, or even some purses.
