Verify voltage current and tip size

Confirm your laptop requires exactly 19 V and draws no more than 4.74 A. Measure the existing barrel plug to ensure a 4.5 mm outer diameter and 3.0 mm inner diameter with a centre pin. Check that the original charger is rated at 90 W or lower. The adapter carries CE certification for safety compliance.

Suits owners of compatible 90 W notebooks

Buyers needing a direct replacement for the listed Chicony models will find the correct voltage current and connector. Users whose devices demand higher wattage a different voltage or another tip geometry should look at alternative chargers. Travellers requiring only the adapter without a cord must source the cord separately.

Questions about this item

Does the 19V 4.74A adapter arrive with a mains lead or must I buy one separately?

The package includes one AC adapter and one power cord so nothing extra is required for immediate use.

Which part number should I match — A10-090P3A or A090A076L — when ordering this 90W unit?

Both numbers refer to the same 19V 4.74A model; match either to your laptop's label and the 4.5x3.0mm tip will fit.

Will the 90W rating actually deliver 19V at 4.74A inside my laptop or does it drop under load?

The adapter is specified for 19V 4.74A continuous output, so the 90W figure represents sustained power at the 4.5x3.0mm connector.
