How we ranked these picks

We rank mini power banks by how much everyday charging you get from the smallest, lightest body for the money—not by the biggest mAh number. A pack that fits in a pocket and actually gets carried beats a brick left at home. Magnetic Qi2 charging, fast USB-C output, built-in connectors, and real buyer volume move a pick up; 20,000mAh laptop bricks belong on our laptop power bank lists instead.
