CUKTECH’s 300 W Desktop Charger Wants to Replace Your Entire Drawer of Power Bricks

Summary: The award-winning CUKTECH 30 Charging Station Ultra packs 300 W of total output across five ports into a sleek, desktop-friendly form factor. Powered by 3rd-gen GaN technology and featuring an integrated 1.83-inch IPS real-time display, it offers a single-device solution for powering high-performance laptops, handhelds, and mobile gear.

Key Takeaways

  • Massive 300 W Power Capability: Equipped with three USB-C ports, one USB-A port, and a dedicated DC output capable of outputting up to 300 W on a single line for compatible laptops.
  • Advanced GaN & Thermal Architecture: Features 3rd-generation GaN technology with a PFC + LLC dual architecture to manage thermal loads efficiently while maintaining stable simultaneous power output across five devices.
  • Real-Time Visual Monitoring: Includes an integrated 1.83-inch color-coded IPS display that provides live wattage, voltage, current metrics, and load graphs for every connected device.

Detailed Overview

If you have ever charged a Xiaomi phone with the bundled brick, there is a decent chance CUKTECH’s engineers had a hand in it, even though the name never made it onto the packaging. The company started in 2016 as an OEM building chargers behind the scenes for Xiaomi and other major players before merging with ZMI in 2022 and launching products under its own brand.

That transition from supplier to direct manufacturer has proven successful. The CUKTECH 30 Charging Station Ultra recently secured two wins at the European Product Design Award—one in computer accessories and another in office appliances—for its 300 W GaN-powered design created by Chong Wang and Ziyao Wang.
