Genuine 40W 19V Acer Adapter

This new genuine Acer AC adapter delivers 40 watts at 19 volts and 2.1 amps for compatible Aspire, TravelMate, Extensa and Gateway laptops. It includes the power cord and matches part numbers KP.0400H.003, A13-040N3A, KP.04003.001 and PA-1400-26AW.

Fixed 19V Output Limitation

The adapter provides a single fixed 19V output and cannot negotiate other voltages or higher currents. Laptops that require more than 40 watts or a different voltage will not charge correctly with this unit.

Simple Barrel Connector Installation

Installation is a direct plug of the barrel connector into the laptop DC jack and the IEC cord into a wall outlet. The main failure point is a loose or worn DC jack on the laptop side, which prevents reliable contact even with a working adapter.

Questions about this item

Which Acer models does the A13-040N3A 40W 19V 2.1A adapter fit?

It matches the long list of Aspire E, ES, R, V and TravelMate B, P and Extensa models shown in the compatible-models section, plus the Gateway NE, NV series.

What does the 40 W rating mean when the adapter is plugged into my laptop?

It is the maximum power the brick can deliver continuously at 19 V and 2.1 A, so your laptop will draw up to that level while charging and running.

What connector standard does the A13-040N3A use and what does it limit?

It uses the standard Acer barrel tip that fits the listed models; the 19 V / 2.1 A output caps the power at 40 W for those devices.
