65W 19V AC Adapter for Acer Monitors

This 65 watt power supply delivers 19 volts at 3.42 amps through a 5.5 mm by 1.7 mm barrel connector. It replaces the original adapter for a long list of Acer LCD models including the R240HY, SB220Q, H236HL and G246HL series. The unit accepts 100 to 240 volt AC input for worldwide use.

Continuous 65W Output with Protection Circuits

The adapter sustains its full 65 watt rating under constant load rather than only in short bursts. Built-in overload, short-circuit, zero-voltage and under-voltage protection circuits shut down the output before components overheat or the monitor receives unstable power. This steady delivery keeps the display running during extended work sessions.

Direct Barrel Plug Replacement

Installation is a simple swap: unplug the old brick, connect the 5.5 mm by 1.7 mm tip to the monitor's DC jack, and plug the IEC cord into the wall. The only common issue is selecting a tip with the wrong inner diameter, so verify the 1.7 mm size matches the original adapter before ordering.

Questions about this item

How much heat or noise does this 65 W adapter produce when powering a monitor all day?

The unit has no fan and runs silently; its 19 V 3.42 A output stays within normal temperature limits for a sealed 65 W supply under continuous load.

What must I already own for this 5.5 mm × 1.7 mm plug to work with my Acer display?

You need an Acer monitor from the listed series — such as R240HY, S240HL, G246HL or H236HL — that uses a 19 V DC barrel jack of this exact size.

Will this charger safely replace the original ADP-40KD or PA-1051-91 brick on my older Acer screen?

Yes; it matches the 19 V 3.42 A 65 W rating and 5.5 mm × 1.7 mm connector used by those part numbers, and includes overload, short-circuit and under-voltage protection.
