Models with 20,000mAh to 27,000mAh were favored for their ability to provide multiple laptop or device charges, perfect for travel, remote work, or extended use without outlets.
We chose power banks with multiple ports—especially USB-C PD and USB-A—to support charging multiple devices at once, offering flexibility for various tech setups.
We looked for slim, durable designs that are easy to carry but rugged enough for travel. Compact, lightweight models earned extra points without sacrificing power.
