Direct Replacement for Acer Aspire

The myVolts A13-045N2A is a 19V 2.37A 45W AC adapter built to replace original chargers for compatible Acer Aspire and Gateway laptops. It accepts a 100-240VAC 50/60Hz worldwide input so it works across different mains supplies without a voltage switch. The unit includes over-voltage, over-current and short-circuit output protection. Buyers needing a 65W or 90W adapter for higher-draw models cannot use this unit.

Cool and Quiet 45W Operation

As a sealed switching supply with no moving parts the adapter runs silently and produces only modest warmth during typical charging loads. The 45W maximum output keeps thermal output low enough for desk or bedside use without a fan. Continuous operation at full load will raise the case temperature but stays within normal limits for this power class. There is no acoustic signature to disturb quiet environments.

5.5mm × 3.0mm Smart Tip Connector

The output cable terminates in a 5.5mm outer diameter barrel tip with a 3.0mm inner diameter and no centre pin, matching the listed Acer and Liteon part numbers. This specific geometry means the plug will not fit devices requiring a 4.0mm tip or a centre-pin connector such as certain Asus or Samsung units. The fixed mains lead and DC cable keep the setup simple but limit cable routing flexibility compared with detachable-lead designs.

Questions about this item

How do I connect the A13-045N2A adapter and which tip mistake should I avoid?

Plug the IEC C7 mains lead into the adapter, then attach the 5.5 mm outer-diameter, 3.0 mm inner-diameter smart tip to the laptop — do not use a 4.0 mm tip or any tip with a centre pin, as this unit has no centre pin and will not fit those sockets.

What part of the A13-045N2A charger is most likely to need replacement first?

The detachable IEC C7 mains cable and the 5.5 mm × 3.0 mm smart tip are the wear items; the cable can fray at the strain relief and the tip can loosen after repeated insertions, while the sealed adapter body itself has no user-serviceable parts.

What thermal or power limit appears first when the A13-045N2A runs continuously at full load?

The adapter is rated for 45 W (19 V, 2.37 A) maximum continuous output; its built-in over-current protection (OCP) will trip if the connected device tries to draw more than 2.37 A, and over-voltage protection (OVP) activates if output exceeds 19 V.
