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 or another small device during a power outage. After 12 hours of research and 19 hours of testing, we’ve determined that the ZMI PowerPack 20000 is the best power bank for laptops that charge via USB-C. It fully recharges most laptops at least once at top speed, yet it’s compact enough to carry in a backpack, a laptop bag, or even most purses. Plus, it doubles as a hub, adding ports to your laptop.
