Genuine 45 W Acer AC adapter for Aspire laptops

This genuine Acer power supply delivers 45 watts at 19 volts and 2.37 amps through a 1.1 x 3.0 x 7.7 mm barrel tip. It replaces a wide range of Acer part numbers including KP.0450H.001 and PA-1450-26AC. The unit ships new with a detachable power cord.

Barrel connector limits compatibility to matching

The fixed 1.1 x 3.0 x 7.7 mm tip fits only laptops that accept this exact barrel size and 19 V polarity. It will not work with USB-C charging ports, larger barrel tips or any non-Acer proprietary connectors. Buyers who need a different tip diameter or a USB-C power source must select another adapter.

45 W output decides if this charger can replace

The 45 watt rating must match or exceed the laptop's original adapter wattage for reliable operation. If the original unit is rated higher than 45 W, this adapter may charge slowly or fail under load. Check the laptop's label or manual to confirm the required wattage before ordering.
