Power adapter for Dell laptops

The Dell LA240PM160 delivers 240 W at 19.5 V and 12.3 A through a 7.4 mm by 5.0 mm barrel connector. It accepts a worldwide 100-240 V input at 50-60 Hz and ships with a mains power cord included. This unit is a genuine Dell replacement part built to the original specification.

Who this suits and who should look elsewhere

It suits owners of Dell laptops that require a 240 W adapter with the exact 7.4 mm by 5.0 mm tip. It will not suit devices that need a different voltage, a lower or higher wattage, or a connector size other than 7.4 mm by 5.0 mm. Buyers whose laptops use USB-C charging or a proprietary Dell connector with a different pin layout should look elsewhere.

Deciding specification

The single specification that decides compatibility is the 7.4 mm by 5.0 mm barrel connector paired with 19.5 V output at 240 W. If your laptop demands that exact connector and power rating, this adapter is the correct match.

Questions about this item

How do I connect the 7.4 mm / 5.0 mm connector to my Dell laptop?

Align the barrel tip with the laptop's power port and push straight in until it seats firmly; the 7.4 mm outer diameter and 5.0 mm inner pin match the original Dell jack, so forcing it at an angle is the step most people get wrong.

Which part of this 240 W adapter is likely to need replacement first?

The detachable AC power cord and the DC cable near the barrel connector see the most flexing; inspect both for fraying or kinks after extended use.

What limits continuous output on this 19.5 V 12.3 A unit during long sessions?

Internal overheating protection (IO) will throttle or shut down the adapter if sustained 240 W load pushes temperatures past the safety threshold.
