  • Worldwide 100-240 V input works anywhere

19V AC Adapter for Asus ASUSPRO B400V

This 19V AC adapter is built as a direct replacement charger for the Asus ASUSPRO B400V notebook. It accepts worldwide mains input from 100 to 240VAC at 50/60Hz, so it works across different regions without a separate voltage converter. The unit ships new with a total power cord length of 10 ft, giving flexibility for desk or floor outlets.

Replaces a lost or failing original charger

When the factory-supplied adapter is missing, damaged or no longer holds a stable output, this unit restores full charging capability. The jump is worth it if the original cable is frayed, the barrel connector is loose or the brick overheats under load. Built-in over-current, over-voltage, short-circuit and total-power protection help prevent repeat failures. A smart chip adds overheating protection while anti-interference isolation improves signal stability.

Limited to devices that match the 19V barrel

This adapter only fits laptops that require exactly 19VDC via the same barrel connector used on the ASUSPRO B400V. It cannot charge USB-C devices, higher-voltage workstations or any system with a different pinout or polarity. The fixed 10 ft cable length also means very distant outlets may still need an extension lead. Buyers who need multi-voltage output, USB-C Power Delivery or a detachable cable should look at a different product class.

Questions about this item

What plug does the WAWEIS 19V adapter need on the Asus ASUSPRO B400V?

It uses the original barrel connector that fits the B400V charging port.

What is the step people miss when installing this charger?

Connect the mains lead to the brick first, then plug the barrel tip firmly into the laptop before switching on the wall socket.

Which part of this power supply will need replacing first?

The 10 ft mains cable or the DC cord can wear at the strain reliefs; the brick itself has over-current, over-voltage and short-circuit protection.
