AC adapter for Acer laptops

This 90W power supply delivers 19V at 4.74A through a 5.5x1.7mm barrel connector. It matches the HP-A0904A3 and PA-1900-34 part numbers used across numerous Acer Aspire and V series models. The unit accepts 100-240V input at 50-60Hz for worldwide use. A CE mark confirms basic safety compliance.

Straightforward plug-in replacement

Installation requires only connecting the barrel tip to the laptop and the IEC cord to a wall socket. The critical step is verifying that the device needs exactly 19V and 4.74A with a 5.5x1.7mm plug; mismatched voltage or tip size will prevent charging or cause damage. Polarity is centre-positive, which is standard for the listed Acer models. No drivers or configuration are involved.

Suits owners of listed Acer notebooks

Buyers with an Aspire V3-571G, V5-561G, E5-771G or any model in the compatibility list can use this as a direct spare. It is not for laptops that require a different voltage, current rating or connector diameter. Users needing USB-C Power Delivery or a higher wattage unit for gaming hardware should look elsewhere.
