Replacement 230W AC Adapter for Acer Laptops

This 230W AC adapter replaces Acer PA-1231-16A and compatible chargers for PHN16S-71 series notebooks. It supplies 19.5V at 11.8A to power the laptop and charge the battery whether the system is on or off. The unit is sold new and built for Acer devices only.

Thermals Noise and Power Draw

The adapter accepts worldwide input of 100 to 240V at 50 to 60Hz and delivers up to 230W maximum output. Internal safety circuitry filters voltage spikes and limits output to protect the notebook from electrical hazards. A ruggedised case resists moisture and high humidity during mobile use.

5.5mm Plug Tip Without Center Pin

The connector uses a 5.5mm diameter tip with no centre pin, so it fits only Acer models that require this exact geometry. It does not replace 280W, 300W or 330W adapters. Buyers needing higher wattage or a different tip style must select another charger.

Questions about this item

How do I install the iTekiro 230W AC adapter and which step do people often get wrong?

Plug the 5.5 mm tip without a centre pin firmly into the laptop's DC jack; the common mistake is forcing a pin-type connector into the port, which will not fit this model.

What maintenance or replacement will the iTekiro 230W AC adapter need later?

The adapter itself has no user-serviceable parts; if the 6 ft AC cord or 6 ft DC cord shows fraying or the brick stops delivering 19.5 V at 11.8 A, replace the whole unit.

What limit appears first when the iTekiro 230W AC adapter runs under sustained load?

The 230 W output ceiling is reached before thermal throttling engages, so continuous draws above 19.5 V and 11.8 A will trip the internal protection.
