AC adapter Dell N9RDH 165W USB-C GaN, laptop power supply 165 W, USB-C PD output

Dell N9RDH 165W USB-C GaN AC adapter is a compact laptop power supply that delivers up to 165 watts through a single USB-C Power Delivery output. Using gallium nitride (GaN) technology, the adapter is designed to provide efficient energy conversion in a smaller housing compared with traditional silicon-based chargers. It supports fast charging for compatible laptops and can supply stable power to USB-C peripherals while operating in home, office, or travel environments.

Advantages

The GaN design reduces size and heat generation while maintaining high efficiency and a 165W output capacity. A single USB-C PD port simplifies connections and enables universal compatibility with many modern laptops and devices that accept USB-C power. The adapter’s regulated output helps protect connected equipment from voltage spikes and ensures steady charging performance under normal operating conditions.

Suitable for

• Charging USB-C laptops that support Power Delivery up to 165W
• Powering USB-C peripherals such as monitors, docking stations, or portable drives (where supported)
• Use at home, in the office, or while travelling due to its compact GaN form factor

Key specifications

• Output power: up to 165 W via USB-C Power Delivery
• Technology: Gallium nitride (GaN) for reduced size and improved efficiency
• Output interface: single USB-C PD port
• Form factor: compact, travel-friendly power adapter
• Protection features: regulated output for stable voltage and overcurrent protection (typical for PD chargers)

How to use

Connect the USB-C cable to the adapter’s USB-C port and the other end to a compatible laptop or device that supports USB Power Delivery. Ensure the device accepts the required power level; the adapter will negotiate the proper PD profile automatically. Use the adapter with cables rated for the required wattage to maintain safe and efficient charging. Unplug the adapter from the mains when not in use or before connecting or disconnecting devices.

Recommendations

For reliable operation, use the adapter with certified USB-C PD cables and connect it to devices that support USB Power Delivery. Avoid exposing the adapter to excessive moisture, extreme temperatures, or obstructed ventilation. If the connected device does not accept the full 165W, the adapter will supply the maximum power supported by that device’s PD profile.
