240W Zephyrus Charger ADP-240EB B - High-Power Replacement Adapter

In this review the reviewer examines the 240W Zephyrus Charger ADP-240EB B as a direct replacement power adapter for high-performance ASUS ROG and ZenBook Pro Duo laptops. The bottom line: this adapter is for users who need a reliable, high-current power supply that matches the original 20V 12A specification and supports up to 240W of output. It stands out because it reproduces the original adapter's power profile and connector type while adding multiple safety protections, making it a practical choice for gamers, content creators, and anyone who requires full-power charging without carrying the factory unit.

Key Features

• Output 20V 12A: Delivers the full 240W power needed to run high-end gaming laptops and prevent throttling under load.
• Wide input range: Accepts 100~240V at 50-60Hz so it works worldwide without a voltage converter.
• Connector compatibility: Uses a 6.03.7mm barrel connector that fits the same models as the original adapter for a hassle-free swap.
• Multiple protections: Built-in smart chips provide over-charge, over-voltage, over-temperature, over-current, short-circuit, and lightning protection for safer daily use.
• Broad model support: Compatible with many ASUS ROG Zephyrus and ROG Strix 15/17 series and select ZenBook Pro Duo models, reducing the need to hunt for a model-specific unit.
• Complete kit: Ships with the power adapter, AC power cord, and a product manual so it is ready to use out of the box.

Who It's For

This adapter is aimed at owners of ASUS ROG Zephyrus S15/S17, M16 GU603 models, ROG Strix Scar and Strix G series, and ZenBook Pro Duo 15 who need a full-power replacement that mirrors the original ADP-240EB B specification. It is particularly useful for gamers and creative professionals who push CPU and GPU performance and therefore require uninterrupted 240W supply to avoid performance drops.

Those who should look elsewhere include casual laptop users with lower-powered models or anyone whose machine specifies a different connector size or lower maximum amperage. Also, users who require a manufacturer warranty tied to an original-branded adapter may prefer buying directly from the laptop maker.
