Seinänturi Dudao A28 45W GaN USB-C — 45W USB-C-pikalaturi, GaN-teknologia

Dudao A28 is a compact wall charger with a single USB-C output and a 45W power rating. Using GaN (gallium nitride) technology, the charger achieves a smaller size and improved energy efficiency compared with traditional silicon adapters. It is designed to provide USB-C Power Delivery to compatible laptops, tablets and smartphones, delivering faster charge times and stable power delivery for everyday use at home, in the office or while travelling.

Advantages

GaN technology reduces heat generation and allows a more compact housing without sacrificing output power. The single 45W USB-C port supports higher charging currents and voltage negotiation via USB Power Delivery, enabling quicker top-ups for devices that accept up to 45W input. The charger offers stable voltage regulation and built-in protections against overcurrent, overvoltage and short circuit, improving device safety and reliability during charging.

Suitable for

• Charging USB-C laptops and ultrabooks that accept up to 45W input
• Powering tablets and larger smartphones for faster charging sessions
• Everyday home and office charging where a compact, portable adapter is preferred
• Travel use due to reduced size and weight compared with conventional chargers

Key specifications

• Output: single USB-C port with Power Delivery support
• Maximum power output: 45 watts
• Technology: Gallium nitride (GaN) for compact form factor and improved efficiency
• Protection features: overcurrent, overvoltage and short-circuit protection
• Intended use: charging laptops, tablets and smartphones with USB-C PD support

How to use

Connect the Dudao A28 to a compatible mains outlet, then plug a USB-C to USB-C cable (or USB-C to device-specific cable) between the charger's USB-C port and the device. The charger and the device negotiate the appropriate voltage and current using USB Power Delivery; charging begins automatically once communication is established. Ensure the connected device supports USB-C PD to achieve optimal charging speed and monitor device temperature while charging larger batteries.

Recommendations

Use a high-quality, PD-capable USB-C cable rated for the desired current to ensure safe and efficient charging. Avoid obstructing airflow around the charger during use and disconnect the charger from the mains when not in use. Do not use the charger if the housing is damaged or if it emits unusual heat or noise; in such cases, discontinue use and seek a qualified inspection or replacement.
