King Ma 65W GaN Laptop Charger with PD 3.0

The King Ma 65W GaN laptop charger is a compact, two-port PD 3.0 power adapter that delivers up to 65 watts for USB-C devices and includes a 5.5×2.5mm fast-charge cable for compatible laptops.

This slim GaN (gallium nitride) charger combines high-density power with a small footprint so you can charge a laptop, tablet and phone from a single wall outlet. It uses modern power-delivery protocols for faster, more efficient charging and includes safety protections against overheating and short circuits. The bundled cable and adapter options make it suitable for a wide range of ASUS and other laptop models, while the second USB-C port lets you charge a phone or accessory simultaneously.

Which devices will this charger power reliably?

The charger supports USB Power Delivery (PD) outputs up to 65W for laptops, and lower wattage negotiation for tablets and phones. It ships with a 5.5×2.5mm-style cable for many ASUS and similar models, and its USB-C PD port works with any device that accepts PD charging.

• Up to 65W output over USB-C PD for compatible laptops and ultrabooks.
• Secondary USB-C port for phones, earbuds, tablets, or accessories.
• Bundled 5.5×2.5mm cable fits many ASUS/Dell barrel-jack laptops — verify your model’s plug size.
• Automatic wattage negotiation protects smaller devices from overcurrent.

How does GaN technology benefit daily charging?

GaN semiconductors allow the adapter to deliver the same power as older brick chargers while being significantly smaller and lighter. Less heat is produced during operation, which helps efficiency and makes the adapter more travel-friendly.

• Smaller physical size compared to silicon-based chargers.
• Improved thermal performance reduces heat buildup during long charges.
• Greater energy efficiency lowers wasted power and keeps the unit cooler.

Is this charger safe and durable for everyday use?

King Ma’s charger includes multiple built-in protections and a durable cable design to handle daily wear. The PD circuitry and safety features work together to limit voltage spikes, overcurrent, and overheating while the cable’s PVC jacket resists bending and tangling.

• Over-voltage, over-current and short-circuit protection included.
• Durable PVC charging cable rated for frequent bending and travel.
• Compact foldable plug and robust housing for safe transportation.

What do I need to check before I buy?

Confirm your laptop’s charging port type and required barrel size before purchasing the bundled cable. If your computer accepts USB-C PD, you can use the adapter’s USB-C port directly; otherwise verify the 5.5×2.5mm connector fits your model or use an appropriate interchangeable tip.

• Check whether your laptop uses USB-C PD or a barrel plug (measure barrel size).
• Confirm required wattage — many mid-size laptops work well at 65W.
• Bring your laptop model number to compare port compatibility with the seller’s listing.

Who is this for: The King Ma 65W GaN charger is aimed at mobile professionals and students who want a lighter, multi-device wall charger that still delivers laptop-class power. Choose this adapter if you need a compact travel charger with PD 3.0 support and a bundled 5.5×2.5mm fast-charge cable for compatible ASUS/Dell-style laptops; if your machine requires a different barrel size or proprietary tip, check compatibility or consider a suitable tip adaptor.
