19V 3.42A 65W AC Adapter with 4.0 mm Tip

This AC adapter delivers 19V at 3.42A for a total of 65W output. It replaces Asus 33W, 45W and 65W units and fits models such as the M509DA, F505ZA, X556U and UX430UN series. The 4.0 mm barrel tip is the critical fitment detail.

Installation check and common pitfall

Verify the plug tip diameter is 4.0 mm against the laptop socket before connecting. The adapter includes a 6 ft AC cord and a 6 ft DC cord for reach. A frequent issue is ordering the wrong tip size, which prevents a secure connection.

Sustained-load behaviour

Comprehensive internal safety features filter input line voltage spikes or surges and limit output voltage or current to protect the laptop. High power efficiency provides consistent and continuous power during extended use. The ruggedized case withstands harsh mobile environments and seals against moisture.

Questions about this item

How can I confirm the 19V 3.42A adapter is charging the laptop correctly after plugging it in?

The laptop power indicator should light and the battery icon in the OS must show it is charging; the adapter replaces Asus 33W, 45W and 65W units so it delivers the same 65W maximum output

What cables are included and is anything else required to start using the charger?

The box contains a 6 ft UL listed 2-prong AC cord and a 6 ft DC cord with the 4.0 mm tip attached; no extra parts are needed for supported Asus models

How do I know whether the 4.0 mm tip version is the right one for my Asus laptop?

Match the tip diameter to the port on models such as UX430UN, UX431FA, UX431FN, UX433FA, UX461FA, UX461UA, X505ZA, X540YA, X556U, X556UA, X556UQ or W202NA; the supplier title lists every compatible part number
