LJO-EEIH 12V Power Cord for Dell 22-27 Inch Monitors

LJO-EEIH 12V power cord is a direct replacement cable for a range of Dell 22"–27" monitors, delivering up to 12V 5A (60W) of stable power for reliable screen operation.

If your Dell monitor stopped powering on or the original cord was misplaced, this replacement by LJO-EEIH restores reliable power without replacing the entire adapter. Built to match specific Dell P/Ns (ADP-40DD B, ADP-40DD BA, PA-1041 series), the cord supports many models that require a 12V DC input. It is not compatible with Dell monitors that need 19.5V — please verify your monitor’s voltage before ordering.

Which Dell monitors will this power cord work with?

This cable is designed for a wide set of Dell monitors in the 22" to 27" range that accept a 12V DC input. It lists compatibility with many S-series models, including S2216, S2240, S2316, S2340, S2440 and S2740 family monitors. Always confirm the voltage on your monitor’s label or manual to ensure it requires 12V rather than 19.5V.

• Compatible with S2216H/M, S2240L/T/M, S2316H/M, S2340L/M, S2440L, S2740L models.
• Matches power module part numbers: ADP-40DD B / BA, PA-1041-0 / -71 / -81.
• Supports monitor sizes from 22" up to 27" that use 12V DC input.

How does the 12V 5A (60W) rating affect performance and safety?

The 12V 5A rating gives up to 60 watts of power, sufficient for the specified monitor models while maintaining stable voltage. Built-in safeguards protect against over-voltage, over-current, and short circuits, preserving both the cord and the connected monitor. Proper wattage prevents flicker, unexpected shutdowns, or damage that can arise from using an underpowered supply.

• Delivers stable 12V output with up to 5A current capacity for peak performance.
• Integrated protection circuits guard against common power faults.
• Designed to reduce electrical noise and maintain consistent screen operation.

Will this cord fit my current power adapter and how easy is it to replace?

The cord is made to plug into compatible Dell power bricks that accept the same DC connector and P/N family. Installation is straightforward: unplug the old cord from the adapter and connect this replacement one; no tools or technical setup are required. For monitors that use an external power brick, this cord replaces the cable portion rather than the entire adapter unit.

• Direct swap for cords using the listed PA-1041 and ADP-40DD part numbers.
• Quick plug-and-play replacement—no configuration needed.
• Works with external adapter bricks, replacing only the AC-to-DC cable portion.

What should I check before buying this replacement power cord?

Before purchasing, inspect the monitor’s power label or the original adapter for output voltage and connector type. This LJO-EEIH cord supports 12V DC output—do not use it with Dell monitors that require 19.5V. Confirm the part number listed in your monitor’s manual if possible to ensure an exact match.

• Verify your monitor’s required voltage is 12V (not 19.5V).
• Compare the adapter P/N (ADP-40DD, PA-1041 variants) with your original unit.
• Check the connector shape and size visually to ensure compatibility.

Who is this for: this LJO-EEIH 12V 5A replacement power cord is ideal for home users, office IT teams, refurbishers, and anyone with compatible Dell 22"–27" monitors who needs a dependable, safety-minded replacement cable. It’s especially useful when the original cord is lost, damaged, or when you need a spare for a multi-monitor setup. If your monitor explicitly requires 12V DC and matches the listed P/Ns, this cord offers a practical and cost-effective way to restore power and extend the life of your display.
