Cuktech AD1003EU 100W GaN mains charger with 2× USB-C, 1× USB-A and cable, white

The Cuktech AD1003EU 100W GaN mains charger is a compact multi‑port power adapter designed to charge laptops, tablets, smartphones and other USB devices. It uses gallium nitride (GaN) technology to provide efficient mains power conversion in a smaller enclosure and includes two USB‑C ports, one USB‑A port and an integrated cable to support simultaneous charging of several devices. The white finish and travel‑friendly size make it suitable for home, office and on‑the‑go use.

Advantages

The charger delivers up to 100W total output while GaN semiconductor design reduces heat and physical size compared with traditional silicon chargers. Dual USB‑C ports allow flexible distribution of power between modern laptops and mobile devices, while the additional USB‑A port supports legacy devices and accessories. The integrated cable increases convenience by providing an always‑available connection without adding a separate lead.

Suitable for

• Charging USB‑C laptops that accept up to 100W power delivery
• Powering tablets and large-screen devices
• Rapid charging of smartphones and USB accessories
• Users who need multiple ports for travel or desk use

When it may not be suitable

This charger provides a combined maximum of 100W; when multiple ports are used simultaneously, the per‑port power available may be lower than the device's maximum charging capability. It is not a specialized charger for devices that require proprietary power protocols beyond standard USB‑C PD or USB‑A charging profiles. Users with devices that draw more than 100W continuously should choose a higher‑power solution.

Key specifications

• Maximum combined output power: up to 100 watts
• Port configuration: 2 × USB‑C, 1 × USB‑A, plus integrated cable
• Technology: GaN (gallium nitride) power conversion
• Colour: white
• Intended use: mains/AC powered USB charger for portable devices

How to use

Plug the charger into an appropriate mains outlet and connect devices to the USB‑C or USB‑A ports or use the integrated cable. If charging multiple devices, check device power requirements and allow the charger to allocate output according to connected loads. Ensure the charger and devices are placed on a stable, well‑ventilated surface while in use to avoid overheating. Disconnect when charging is complete or when the charger is not in use.

What to consider before purchase

• Confirm your device's maximum charging wattage and whether it supports standard USB‑C Power Delivery profiles.
• Consider the total power needs when planning to charge multiple devices at once.
• Check plug compatibility with local mains outlets or the need for an adapter when travelling.

Usage recommendations

Use USB‑C ports for devices that support Power Delivery to make best use of the 100W capability, reserve the USB‑A port for accessories or devices that require legacy USB‑A connections, and avoid covering the charger during heavy use to maintain proper cooling.
