Replacement AC Adapter for Acer and Gateway Laptops

This 90W power supply replaces the Acer HIPRO HP-A0904A3 and LiteON PA-1900-34 units. It delivers 19V at 4.74A through a 5.5mm by 1.7mm barrel tip. The adapter suits owners of compatible Acer and Gateway notebooks who need a new mains charger.

Steady Output with Built-In Protections

The unit accepts 100-240VAC at 50/60Hz for worldwide use. It maintains a constant 19VDC 4.74A output under continuous load. Over-voltage, over-current and short-circuit protections guard the laptop and the adapter itself during prolonged charging sessions.

Check Tip Polarity and Model Match Before Ordering

Verify that the original charger shows 19V and 4.74A on its label. Confirm the barrel connector measures 5.5mm outer diameter and 1.7mm inner diameter with centre-positive polarity. Buyers whose laptops require a different voltage, current or tip size cannot use this adapter.

Questions about this item

Does the 90 W adapter run hot or make fan noise when powering a laptop all day?

The brick has no fan; it relies on passive cooling and built-in OVP, OCP and SCP protection to stay safe during continuous use.

What cable or connector must I already have to plug this 5.5 mm × 1.7 mm barrel tip into the wall?

You need a standard IEC C7 or C5 mains lead that matches your local socket; the adapter itself only provides the DC barrel output.

Will this 19 V 4.74 A unit safely replace the original LiteON PA-1900-34 or HIPRO HP-A0904A3 on an older Acer or Gateway notebook?

Yes — it matches the 19 V 4.74 A 90 W rating and 5.5 mm × 1.7 mm tip specified for those models.
