240W Power Adapter for Dell Alienware & Precision

This 240-watt AC adapter delivers 19.5 volts at 12.3 amps and replaces Dell part numbers such as PA-9E, J211H and Y044M.

The unit accepts 100 to 240 volts input at 50 to 60 Hz for worldwide use.

For owners of listed Dell laptops needing a 240W

Buyers whose Dell model appears in the compatibility list and whose original charger matches the 19.5V 12.3A output and 7.4 mm tip will find a direct fit. Units requiring a different voltage, a higher wattage or a connector size other than 7.4 mm by 5.0 mm cannot use this adapter.

7.4 mm x 5.0 mm barrel connector

The tip dimensions and 19.5V 12.3A rating are the single specifications that decide compatibility. Verify the original power supply label and the laptop jack size before ordering to ensure an exact match.

Questions about this item

Will the 7.4mm by 5.0mm connector tip wear out and need replacement?

The 7.4mm by 5.0mm barrel connector is a solid metal tip rated for thousands of insertion cycles; under normal daily use it typically lasts the life of the adapter without requiring replacement.

What limits continuous output when the adapter runs at 240W for hours?

The 19.5V 12.3A rating is the sustained maximum; internal overcurrent and over-temperature protection will reduce output or shut the unit down if that limit is exceeded for prolonged periods.

How hot and loud does the 240W brick get during all-day operation?

The adapter uses passive cooling with high-temperature-resistant components; it runs warm but silent, and UL-listed overheat protection prevents unsafe surface temperatures during continuous load.
