ASUS 0A001-00860300 power adapter/inverter Indoor 120 W Black

The Asus Laptop AC Adapter 120W 20V 3P 4.5PHI is an external power supply designed to deliver stable power to compatible Asus notebooks. It provides a 20V nominal output and up to 120 watts of power through a DC connector with a 4.5 mm pin-and-hole (4.5PHI) interface, while the mains input uses a three-pin plug. This adapter is intended as a replacement or spare unit that matches the original electrical parameters to maintain charging performance and reliable operation during use at home, in the office, or on the go.

Advantages

The adapter delivers consistent voltage and sufficient wattage for charging and powering mid- to high-performance Asus laptops, reducing risk of underpowering or slow charging. Its standardized 3-pin mains connector ensures safe connection to grounded outlets, and the 4.5PHI DC plug provides a secure fit to compatible laptop power inlets. The unit is compact relative to its power class and designed for straightforward replacement of original adapters with matching electrical characteristics.

Suitable for

• Charging compatible Asus notebooks that use a 4.5PHI DC connector and 20V input
• Replacing a lost or damaged original Asus power adapter
• Providing a spare adapter for travel between home and workplace
• Powering laptops during high-load tasks that require up to 120W

Key specifications

• Output voltage: 20 V
• Maximum output power: 120 W
• DC connector type: 4.5 mm pin-and-hole (4.5PHI)
• Mains connector: 3-pin grounded plug
• Compatibility: Asus laptops requiring 20V and 4.5PHI connector

How to use

Ensure the laptop requires a 20V input and a 4.5PHI DC connector before connecting the adapter. Plug the mains lead into a compatible grounded outlet, connect the DC plug securely into the laptop’s power inlet, and verify the device shows charging or external power status. Avoid forcing the connector; it should insert smoothly. Disconnect from the mains and the laptop when not in use or during extended storage.

Recommendations

Use only with devices that match the stated voltage and connector type. Avoid exposing the adapter to liquids, excessive heat, or prolonged direct sunlight. For best results, allow adequate ventilation around the adapter during high-load operation and inspect the cable and connectors periodically for wear or damage. If the laptop does not charge or behaves unusually, stop use and consult a qualified technician.
