240 W Dell AC adapter with 7.4 mm barrel

This 19.5 V 12.3 A power supply replaces original Dell chargers for G-Series, Alienware and Precision laptops. It delivers up to 240 W and automatically adjusts to 180 W or 130 W systems. The 7.4 mm by 5.0 mm barrel connector fits the large port used on many high-performance models. Condition is new.

Check barrel size and wattage before ordering

Verify that your laptop uses the 7.4 mm barrel plug and requires 19.5 V input. Confirm the original adapter is rated 240 W, 180 W or 130 W; this unit covers all three. Models such as the Alienware x16 R2 with RTX 4080 or 4090 need a different connector and are not supported. Input voltage range is 100 to 240 V at 50 to 60 Hz.

Suits owners of listed Dell gaming

Buyers with compatible G15, G16, G7, G5, Precision 7000 or Alienware m15, m17, x15, x17 systems can use this charger. It is not for laptops that charge over USB-C or use a smaller barrel tip. Users needing a higher-wattage unit for RTX 4080 or 4090 configurations should look elsewhere.

Questions about this item

What cables and connectors come with the NATNO BRJ90200500 adapter, and does it include a mains lead?

The adapter has a fixed 7.4 mm × 5.0 mm barrel connector and a detachable IEC C7 figure-8 mains lead is included in the box.

My laptop needs a 180 W charger; will this 240 W unit work safely?

Yes — the adapter is backward compatible with Dell 180 W (19.5 V 9.23 A) and 130 W (19.5 V 6.7 A) systems and will negotiate the correct power level automatically.

What does the 240 W rating mean when the adapter is plugged into my Precision 7550?

It delivers up to 19.5 V at 12.3 A, giving the full 240 W the workstation requests under heavy load while running cooler than a lower-wattage brick.
