The Anker 313 30W Fast Charger (Model A2639) is a single-port USB-C wall charger designed for fast, efficient charging of modern devices. It uses Gallium Nitride (GaN) technology, which allows it to deliver high power in a much smaller and cooler-running package than traditional silicon chargers. It also includes Anker PowerIQ 3.0, USB Power Delivery (PD), and PPS support for broad compatibility and improved charging speeds.
