90W AC Adapter for Acer Laptops

This genuine Acer 90W AC adapter delivers 19V at 4.74A through a 5.5mm x 1.7mm blue tip connector. It is designed for Acer laptops that require this specific tip style and power rating. The adapter accepts 100-240V input at 50-60Hz for worldwide use. It replaces lost or damaged original chargers for compatible models.

Replaces Acer Part Numbers ADP-90SB BB

This unit supersedes multiple Acer part numbers including AP.09003.021, AP.09001.003, AP.09001.004, AP.09001.005 and AP.09006.005. The upgrade is worth it when your current adapter shows frayed cables, intermittent charging or a loose tip connection. It is not for laptops that use a black tip connector or a different voltage and amperage combination.

Fits Acer Laptops with Blue Tip 5.5mm x 1.7mm Input

The adapter connects directly to the laptop's DC-in jack and requires a standard IEC C7 or C5 mains cord for wall power. US and Canada shipments include the cord; other regions receive the adapter only. It frees you from relying on third-party chargers that may not meet Acer's electrical specifications. Buyers who need a different tip size or higher wattage output cannot use this model.

Questions about this item

What laptop charging port does the 5.5mm x 1.7mm blue tip fit?

The blue tip connects to Acer laptops that use a 5.5mm outer diameter and 1.7mm inner diameter barrel connector. Black-tip adapters are not interchangeable with this one.

How do I install the AC adapter and what step is often missed?

Plug the AC cord into the adapter brick, connect the blue tip to the laptop, then plug the cord into a 100-240V 50-60Hz outlet. The step often missed is ensuring the cord is fully seated in the brick before powering on.

When will the detachable AC power cord need replacement?

Replace the cord if the plug prongs bend, the insulation cracks, or the connector that seats into the adapter brick becomes loose or intermittent.
