19V 2.1A 40W AC Adapter for ONE A150 D150

This OIAGLH power supply delivers 19 volts at 2.1 amps for a total of 40 watts. It matches the APD DA-40A19 and DA-40C19 part numbers used by compatible laptops. The unit is new and built to the original equipment specification. Buyers needing a different voltage or higher wattage should look elsewhere.

Sustained Load Behavior

The adapter maintains the rated 19V 2.1A output continuously within its design limits. Thermal protection engages if internal temperatures exceed safe thresholds during extended operation. No fan is present, so cooling relies on passive convection through the enclosure. Ensure adequate airflow around the brick to prevent throttling over long sessions.

Questions about this item

Does the 40 W adapter stay quiet and cool when it powers a laptop all day?

The 19 V 2.1 A unit has no fan, so it runs silently; its plastic housing dissipates the 40 W load without becoming hot to the touch under normal indoor temperatures.

My ONE A150 only has the original barrel jack — will this charger plug straight in?

The tip matches the DA-40A19 and DA-40C19 specifications used by the ONE A150, D150 and ES1-111M-C40S, so no extra cable or converter is needed.
