Laptop Power Bank Chargers

Laptop power banks split into two categories: ones that actually sustain enough wattage to charge your laptop under load, and ones that technically 'work' while your battery percentage still drops. This list focuses on the first category. Specs are cross-referenced against USB-PD compliance data and aggregated user reports — because a 26,800mAh figure on the box means nothing if the unit throttles to 45W when your machine needs 90.
