Toss the right laptop power bank in your bag, and you'll never need to do that panicked run to the nearest outlet again. A hefty portable charger frees you to sit anywhere with your laptop and keep it running. Power banks with USB-C ports can charge phones and headphones as well, and I’ve tested more than 100 of them over the past few years. These powerful, high-capacity portable batteries are the best ones when laptop charging is a priority. For this guide, I considered power banks that are 20,000 mAh and up, enough to charge most laptops twice.
