Charger NUBIA DAO 80W GaN Charger — 80W USB power adapter, GaN technology

The NUBIA DAO 80W GaN Charger is an 80-watt USB power adapter that uses gallium nitride (GaN) semiconductor technology to deliver high-power charging in a compact housing. Designed for modern USB-powered devices, this charger supports fast charging of laptops, tablets, smartphones and other peripherals while reducing size and heat compared with traditional silicon-based chargers. Its folding plug and lightweight construction make it suitable for everyday use at home, in the office and while travelling.

Advantages

GaN semiconductor design improves energy efficiency and thermal performance, allowing high output in a smaller package. The 80W maximum output provides sufficient power to charge larger devices such as laptops and fast-charge compatible tablets and phones. The compact form factor and reduced heat generation contribute to safer, more reliable operation during extended use. Universal USB connectivity makes it compatible with a wide range of USB-powered devices when combined with appropriate cables.

Suitable for

• Charging laptops and ultrabooks that accept USB power delivery up to 80W
• Fast charging tablets and large-screen smartphones
• Powering USB-C hubs, portable monitors and mobile batteries
• Everyday charging at home, in the office or on business and leisure travel

Key specifications

• Maximum output power: 80 watts
• Semiconductor technology: GaN (gallium nitride)
• Output interfaces: USB (specify cable type as required by device)
• Form factor: compact, foldable plug for portability
• Typical uses: high-power USB charging for laptops, tablets, smartphones and peripherals

How to use

Connect a compatible USB cable to the charger and to the device you want to charge. Ensure the cable supports the required power delivery for your device; for laptops and other high-power devices use a cable and device that support USB Power Delivery or the appropriate fast-charging standard. Insert the charger into a suitable mains outlet and monitor device charging status. Unplug the charger when charging is complete or when not in use. Avoid using the charger in wet or excessively dusty environments and keep ventilation clear to maintain thermal performance.

Usage recommendations

Use high-quality, certified USB-C or USB cables rated for high current when charging laptops or devices that require near-maximum wattage. Check device compatibility with USB Power Delivery profiles to ensure optimal charging speeds and follow device manufacturer guidelines for battery care.
