19V 3.42A 65W AC adapter with 5.5x1.7mm connector for Acer Aspire E, ES, F, V, R, S and Aspire 3 and 5 series laptops

  • Worldwide voltage input 100-240V powers the adapter anywhere
  • 65W output at 19V 3.42A charges compatible laptops efficiently
  • 5mm x 1.7mm barrel connector fits listed Acer Aspire models
  • CE FCC RoHS certified with over-voltage over-load over-current short-circuit protection
  • New condition ensures full performance from first use

What this adapter replaces

This 19V 3.42A 65W AC adapter supplies power to compatible Acer Aspire laptops that require a 5.5x1.7mm barrel connector. It suits owners of models such as the E15, E5-573, V5-571 and R3-471T who need a direct replacement for a lost or damaged original charger. Buyers whose laptops demand a different voltage, amperage or tip size cannot use this unit.

Thermals noise and power draw

The adapter accepts 100-240V 50-60Hz mains input and delivers a regulated 19V 3.42A output up to 65W. It carries CE, FCC and RoHS certification and includes over-voltage, over-load, over-current and short-circuit protection. In normal operation it runs silently with no moving parts and draws only the power the connected laptop requests.

Behaviour under sustained load

When a laptop continuously draws the full 65W, the adapter maintains the specified 19V 3.42A output within its protection limits. The built-in safeguards prevent overheating or voltage drift during extended charging sessions. It is not intended for devices that require higher wattage or a different connector polarity.

Questions about this item

How do I connect the 5.5mm x 1.7mm barrel plug to my Acer Aspire E15 E5-573 and what is the common mistake?

Align the centre pin with the laptop socket and push straight in until it seats firmly; the frequent error is forcing the plug at an angle which bends the 1.7 mm pin.

Which part of this 65 W adapter will likely need replacement first during long-term ownership?

The detachable AC mains lead wears out before the brick; swap it with any standard IEC C7 figure-8 cable rated for 100-240 V.

What thermal limit appears first when this 19 V 3.42 A unit runs continuously at full load?

Internal over-temperature protection triggers and shuts the output off until the brick cools, preventing component damage.
