20V 9A 180W ADP-180TB H AC Adapter for Asus ROG Zephyrus - Reliable

In this review the 20V 9A 180W ADP-180TB H AC Adapter is presented as a direct-replacement power option for users of several Asus TUF and ROG Zephyrus laptops. The bottom line: this adapter is for anyone who needs a reliable, full-power replacement or spare that offers the correct 20V 9A output and the uncommon 6.0x3.7mm barrel connector. Our review finds it particularly useful when original chargers are lost or fail, because it delivers the 180W the machine expects and includes a US power cord or alternate plug on request.

Key Features

• Full 180W output: Provides the 20V and 9A power required to run high-performance Asus gaming laptops at expected performance without throttling due to underpowered supply.
• Wide input range: Accepts AC100-240V 50/60Hz so it works internationally with the correct plug and avoids the need for a bulky transformer.
• Correct connector size: Uses the 6.0x3.7mm barrel which matches specified Asus models rather than more common 5.5x2.5mm or 4.5x3.0mm tips.
• Includes cord: Ships with 1x new power supply and 1x free US power cord, and the seller offers other plug types on request to fit regional outlets.
• Replacement compatibility: Matches multiple Asus part numbers and is listed as compatible with many TUF and ROG Zephyrus G14/G15/G series models, simplifying compatibility checks.

Who It's For

This adapter is aimed at owners of supported Asus TUF and ROG Zephyrus laptops who need a direct replacement that restores full charging and power delivery. It is especially relevant for gamers and creators who require the full 180W to maintain peak CPU and GPU performance while charging under load.

It is less suitable for users with laptops that use a different barrel size or for those who need USB-C PD charging; check the connector and part numbers carefully before purchase to avoid a mismatch.
