Blueskysea 240W AC Adapter 20V 12A

This 240 watt AC adapter delivers 20 volts at 12 amps through a 6.0 by 3.7 millimetre barrel plug. It replaces the Chicony ADP-240EB B and accepts a 100 to 240 volt input at 50 to 60 hertz. The unit ships with a matching AC cable.

Suits Zephyrus and Strix Scar laptops

It fits ROG Zephyrus G14 G15 M16 G16 S15 S17 and ROG Strix Scar 15 17 models including G533 and G733 series. Buyers whose laptop draws more than 240 watts or uses a different plug size should look at another adapter. The adapter also covers 180 watt and 200 watt compatible units.

Output fixed at 20V 12A 240W

The single specification that decides fit is the 20 volt 12 amp 240 watt output combined with the 6.0 by 3.7 millimetre DC connector. If your device requires a different voltage, amperage or plug geometry this adapter will not work.

Questions about this item

What wall-outlet voltage and frequency range does this adapter accept?

It accepts 100-240V at 50-60Hz, so it works on mains supplies worldwide without a voltage converter.

Can I use this 240W adapter on a laptop that originally shipped with a 180W or 200W charger?

Yes, it is compatible with 180W and 200W ROG Zephyrus models because the laptop only draws the power it needs.

How can I confirm the adapter is delivering the correct 20V 12A output after I plug it in?

The laptop’s battery indicator should show charging at full speed and the adapter’s LED (if present) will stay solid, confirming 20V 12A delivery.
