Replacement adapter for Asus B400 and B451 series

This 65W AC adapter replaces original Asus 45W and 65W chargers for compatible B400 and B451 models. It delivers 19V at up to 3.42A through a 4.5mm tip with centre pin. The unit accepts 100 to 240V input at 50 to 60Hz for worldwide use.

65W output covers 45W and 65W requirements

Maximum output is 65W at 19V and 3.42A, with a lower range down to 2.37A. It comfortably powers laptops that shipped with 45W or 65W adapters. It does not replace 90W chargers, so machines needing higher wattage are not supported.

Extra-long cords and rugged case for mobile use

A 6ft UL-listed 2-prong AC cord and a 6ft DC cord give extended reach without extension leads. The ruggedised case resists moisture and high humidity. Internal safety features filter voltage spikes and limit output to protect the laptop.

Questions about this item

Will the 4.5 mm centre-pin tip fit the charging port on my older Asus B400 series laptop?

Yes, the 4.5 mm tip with centre pin matches the connector used on Asus B400 and B451 models listed in the compatibility data.

How can I confirm the adapter is delivering the rated 19 V 3.42 A after I plug it in?

The green LED on the adapter brick lights when the unit is powered, and the laptop battery icon should show charging within seconds of connection.

Does the package include both the AC wall cord and the DC laptop cable, or must I buy one separately?

Both cords are included: a 6 ft UL-listed 2-prong AC cord and a 6 ft DC output cable are supplied in the box.
