USB-C Power Delivery 3.1 Architecture

Charging a modern 16-inch laptop in the field requires more than just high capacity; it requires advanced voltage stepping. The Anker Prime Power Bank implements the latest USB-C Power Delivery 3.1 standard, allowing a single port to push a massive 140 Watts.

This high-wattage threshold is absolutely essential when field-deploying a premium multi-core laptop architecture under heavy compilation, rendering, or network routing workloads, where standard 60W travel accessories would cause the internal battery cells to steadily drain despite being physically plugged into a line.
