AYKLCZUU 90W Blue Tip HP Adapter

This AYKLCZUU SK90B195462 AC adapter delivers 19.5V at up to 4.62A for 90W maximum output. It accepts 100-240V input and uses a 4.5mm x 3.0mm blue tip connector with a central smart pin. The unit weighs 10 ounces and measures 2.4 x 3.96 x 1.3 inches. It is a new replacement charger for compatible HP laptops.

Suits HP owners needing a 90W smart-pin charger

Buyers with HP models listed such as Pavilion 11, 14, 15, 17, Envy Touchsmart, Spectre x360 13, EliteBook 840 G3-G4 and ZBook 14 can use this adapter. It also covers part numbers including 741727-001, H6Y89AA and PPP009D. Users whose laptops require a different connector shape, a higher wattage rating or a non-smart-pin interface should look at something else.

4.5mm x 3.0mm blue tip with central smart pin

The connector geometry and the smart-pin signalling are the single specification that decides compatibility. The adapter auto-negotiates 90W, 65W or 45W output at 19.5V to match the host device. If your HP laptop uses a different tip size or lacks the centre pin, this unit will not fit or communicate correctly.

Questions about this item

Does this charger include the AC mains cable, or must I supply my own C5 lead?

The 3-prong power cord is included in the box, so no separate mains lead is required.

Will the 4.5 mm × 3.0 mm Blue Tip connector fit the charging port on my HP EliteBook 840 G3?

Yes, the connector matches the 4.5 mm outer and 3.0 mm inner diameter used on the EliteBook 840 G3 and other listed models.

How can I confirm the adapter is delivering the correct 19.5 V output after I plug it in?

The smart-pin centre contact lets the laptop identify the charger; the battery icon will show charging at 90 W, 65 W or 45 W depending on the model.
