The best portable laptop charger

Read the full portable laptop charger guide here. We spent 15 hours researching and 41 hours testing five top portable laptop chargers, and we found that the Mophie Powerstation AC is the best option if you want the ability to charge your computer and smaller devices while traveling, in an emergency, or whenever power outlets are out of reach. It can power laptops as robust as the 15-inch MacBook Pro, it's compact and lightweight, and it charges via USB-C—an increasingly ubiquitous standard. Mophie's charger is the one we'd buy ourselves. It's the smallest laptop charger we tested and one of the lightest. But it still performed well in our testing with more than 100 W of power output and enough capacity to bring a dead MacBook Air up to 81 percent charged, even during heavy use. It also has the best look and feel of any we tried—we really like how its slim, portable design and professional-looking fabric exterior is complemented by well-placed ports and a magnetic rubber flap protecting the AC output port. Plus, it's made by a company we trust, and its 24-month warranty is as good as any we found.
