Whether you live in a disaster-prone area, are a digital nomad working on the go, have to take notes during a long lecture, or have any other need to extend your laptop's run time, the portable chargers on our list will get the job done. With one of these external batteries, you’ll no longer have to strategically choose work or study locations based on their proximity to an AC power socket.

Editor's Notes

December 30, 2020:

There are a lot of power banks out there, but not all of them have enough capacity to accommodate laptops. The RavPower PB055, Anker Powerhouse 100, and Mophie Powerstation all feature both AC and USB-C PD output, so as long as you have your laptop's original power brick, they should work. If you don't have the original charging brick, consider the MaxOak K2, which comes with a set of interchangeable adapters that plug into its DC barrel receptacles. If you don't need traditional or AC power at all, the iMuto Power Bank is a great choice, although its brick-style design makes it a little too cumbersome for slipping into a laptop case.

January 01, 2019:

We primarily went with models that excelled in efficiency and versatility rather than those with the largest battery capacity. There were one main reasons for this: the first being that the smaller, more efficient models tend to be airplane-friendly, whereas there is no way you'll be able to lug a monster battery past any major airline's security check. Though some of our options do have larger capacities, the smaller ones, such as our #1 and #3 pick, tend to have more useful or novel features, such as solar-charging capabilities.
