Power for compatible Acer laptops

This 135W AC adapter delivers 19V at 7.1A through a 5.5x1.7mm plug without a centre pin. It replaces Acer 135W and 90W chargers listed in the compatibility table. It does not replace 180W or 230W units.

Thermals and power draw

High power efficiency provides a steady output while the durable case resists extreme conditions and seals out water and humidity. Built-in overload, short-circuit, over-voltage, over-current and over-temperature protections manage heat and electrical stress during normal operation.

Build quality and daily use

A UL-listed 6 ft AC cord and a 6 ft DC cord give 12 ft total reach without extension leads. The rugged housing withstands humidity and temperature extremes. Buyers needing an 180W or 230W adapter for larger Acer models cannot use this unit.

Questions about this item

How do I connect the 5.5 x 1.7 mm plug without a centre pin and what step do people miss?

Align the plug with the laptop's charging port and push straight in until it seats firmly; the step often missed is confirming the laptop shows the charging indicator before assuming the connection is complete.

What maintenance or replacement will the 6 ft AC cord and 6 ft DC cord need over time?

Inspect both cords periodically for fraying, kinks or damaged insulation; replace the entire adapter if either cord shows exposed conductors or the plug tip becomes loose or bent.

At what power limit does this 135 W adapter stop being suitable under sustained load?

It is rated for 135 W maximum output; sustained demand above that — such as from a system requiring a 180 W or 230 W supply — will cause the adapter to trigger its overload protection and shut down.
