100W GaN Charger for Laptops and Phones

This Anker charger delivers up to 100W from either USB-C port using GaN technology, sustaining peak output up to twice as long as typical 100W chargers. It suits professionals who need reliable power for laptops, phones, and tablets during long work sessions or travel. The foldable plug and compact 2.72 x 2.17 x 1.34" frame make it easy to carry daily.

Replaces Bulky Multi-Port Bricks

It consolidates three ports — two USB-C and one USB-A — into a unit 330% smaller than conventional chargers, removing the need to pack separate adapters for each device. The upgrade is worthwhile when you regularly charge a laptop alongside a phone and earbuds and want a single, pocketable solution. Low-current mode at 95W + 5W activates automatically for earbuds after one minute at or below 5W.

Sustained Output with Live Thermal Data

The smart display shows real-time power, voltage, and temperature so you can see how the charger behaves under continuous load rather than only in short bursts. Milestone tracking records total usage hours, giving visibility into long-term performance. A 4.9 ft USB-C to USB-C cable is included for immediate use.
