For owners of compatible Acer laptops needing

Buyers whose devices require a different voltage, a higher wattage, or a barrel connector other than 3.0mm by 1.1mm should look at other options. The adapter is designed specifically for the listed Acer part numbers and will not suit machines with proprietary or USB-C charging ports.

The 3.0mm by 1.1mm DC connector decides fit

Only laptops that specify this exact barrel size and the 19V 2.37A output will work correctly with this adapter. Verify the original charger markings before ordering to avoid an incompatible connection.

Questions about this item

Will the DC connector wear out and need replacement?

The adapter uses a 3.0 mm by 1.1 mm barrel tip rated for the 45 W output; normal laptop insertion cycles rarely damage it.

What limits continuous operation first — heat or voltage regulation?

Built-in over-voltage, over-current and short-circuit protection engage before thermal limits are reached during sustained 19 V 2.37 A load.

How much heat and fan noise does it produce running all day?

The sealed unit has no fan; it dissipates 45 W passively and stays warm but silent on a desk surface.
