HSXIRQA 90W AC Adapter with Square Yellow Slim Tip

This HSXIRQA adapter delivers 90W at 20V and 4.5A for compatible Lenovo laptops and all-in-one desktops. It suits users who need a replacement charger that matches the original square yellow slim tip connector. The unit is new and rated for worldwide input voltage.

Installation notes and common issues

The corded electric design plugs directly into the device’s square yellow slim tip port without extra tools. A frequent mistake is using it on systems that require more than 90W, which the supplier specifies as unsupported. Verify the connector shape and wattage requirement before connecting.

90W 20V 4.5A output with square yellow slim tip

The single deciding specification is the 90W output at 20V and 4.5A combined with the square yellow slim tip connector. This adapter also works with 65W and 45W devices that share the same tip, but it will not fit laptops needing a different connector or higher power.

Questions about this item

How can I confirm the adapter is delivering the correct 20V 4.5A output after plugging it in?

The adapter includes a built-in chip that automatically adjusts power based on device temperature and battery status, reducing heat and enabling safer charging.

What comes in the box and do I need to buy a separate power cord?

The package contains the 90W AC adapter with an integrated square yellow slim tip connector; no separate cord is required as the cable is permanently attached.

Which wattage version should I choose if my laptop originally shipped with a 65W charger?

This 90W unit is backward-compatible with 65W and 45W devices, so it will safely power laptops that originally used lower-wattage adapters.
